  2. Do the select agent regulations require any physical measures (i.e., cages, safes) to secure shipments containing select agents or toxins prior to being picked up by a commercial carrier for delivery to the intended recipient?

    If the package containing select agents and toxins is labeled generically as "Category A infectious substance" and does not identify the package as containing a select agent or toxin, the package can be placed with other packages in the area the entity uses for shipment of materials.

    Return to top

  3. Is "chain of custody" paperwork required to track a package containing select agents or toxins until the package is provided to the commercial carrier?

    If the package containing select agents and toxins is packaged by the laboratory and labeled generically as "Category A infectious substances" as required by the DOT regulations, the package can be placed with other packages in the area that the entity uses for shipment of materials and does not need to be accompanied by "chain of custody" paperwork.

    However, if the select agents and toxins are sent to another area for packaging and shipping, "chain of custody" paperwork is required to document transfer from the laboratory to the area where packaging occurs. The area where packaging occurs must be listed on the entity's certificate of registration and must meet all the requirements outlined in the select agent regulations as for other registered areas listed on the entity’s certificate of registration. If Tier 1 select agents and toxins will be packaged in the shipping and receiving area, it must meet all provisions associated with Tier 1 requirements. All individuals who will have access to Tier 1 select agents or toxins must also meet Tier 1 requirements and be enrolled in the entity’s suitability assessment program. The area will also be inspected to ensure the entity’s compliance with the select agent regulations.

    Return to top

  4. Is the receiving entity required to use "chain of custody" paperwork to track a package containing select agents or toxins from the time it is received by the entity from a commercial shipper until the package is received by the intended recipient?

    No, the package will not be identified as containing select agents or toxins and will be considered "lost in the crowd" until received by the intended recipient or his/her designee. It should be noted that the package containing select agents and toxins is not considered "received" by the entity until the intended recipient takes possession of the package.

General questions about transferring a select agent or toxin

  1. What is the purpose of an APHIS/CDC Form 2?

    You use an APHIS/CDC Form 2 to request authorization to transfer a select agent or toxin. It also provides documentation of the transfer. By regulation, an APHIS/CDC Form 2 must be completed for each transfer of select agent(s) or toxin(s) and maintained for three years.

    Return to top

  2. Is a transfer authorization from APHIS or CDC needed for intra-entity transfers?

    No, but an intra-entity transfer is limited to those instances where a select agent or toxin is moved from one location within an entity to another (e.g., A Principal Investigator transferring part of his select agent inventory to another Principal Investigator from the same entity). The entity doing an intra-entity transfer must create a record of the intra-entity transfer that must include the following information: the select agent or toxin, quantity, date, sender, and recipient. By regulation, the record has to be maintained for a minimum of three years. If an entity does intra-entity transfers, its security plan must include a protocol for intra-entity transfers including chain-of-custody documents and provisions for safeguarding against theft, loss, or release. For more information regarding intra-entity transfers, refer to the "Select Agent and Toxins Security Document" at http://www.selectagents.gov/resources/Security%20Information%20Document.pdf.

  3. Our diagnostic laboratory, which is not listed on my entity’s approved registration, would like to transfer the select agent that was identified in a clinical sample to a laboratory room listed on my entity's approved certificate of registration. Does this require an approved APHIS/CDC Form 2?

    Yes, the transfer of a select agent from an area not listed on your entity’s approved registration to a laboratory room listed on your entity’s approved registration is NOT considered an intra-entity transfer. Intra-entity transfers involve the transfer of select agents from one registered location to another registered location covered by the same certificate of registration.

    Return to top

  4. Is a transfer authorization from APHIS or CDC needed to transfer toxins in a quantity below the regulated amounts?

    No, a transfer authorization would not be needed for toxins under the control of a principal investigator, treating physician or veterinarian, or commercial manufacturer or distributor if the aggregate amount does not exceed the following amounts: Abrin 100 mg, Botulinum neurotoxin 0.5 mg, Conotoxins (Short, paralytic alpha conotoxins) 100 mg, Diacetoxyscirpenol 1000 mg, Ricin 100 mg, Saxitoxin 100 mg, Staphylcoccal enterotoxin (A, B, C, D, E subtypes) 5 mg, T-2 toxin 1000 mg, and Tetrodotoxin 100 mg. However, as of December 4, 2012, a registered entity transferring an amount of a HHS toxin otherwise excluded from the regulatory requirements must (1) transfer the amount only after the transferor used due diligence and documents that the recipient has a legitimate need to handle or use such toxins, and (2) reports to CDC if they detect a known or suspected violation of Federal law or become aware of suspicious activity related to a select toxin.

    Return to top

  5. Is a transfer authorization from APHIS or CDC needed to transfer attenuated strains of select agents that have been excluded by APHIS or CDC from the Select Agent Regulations?

    No, the regulations establish a procedure by which the Federal Select Agent Program may exclude from the requirements of the select agent regulations an attenuated strain of a select biological agent or toxin determined by the Federal Select Agent Program not to pose a severe threat to public health and safety, animal and plant health, or animal and plant products. The list of approved attenuated strains can be found on the Federal Select Agent Program website at www.selectagents.gov/Select%20Agents%20and%20Toxins%20Exclusions.html. If an attenuated strain of a select biological agent or toxin is not listed at www.selectagents.gov/Select%20Agents%20and%20Toxins%20Exclusions.html, the agent or toxin is still considered a select agent or toxin and would need a transfer authorization from the Federal Select Agent Program.

  6. How do I submit a transfer request (APHIS/CDC Form 2)?

    You may submit your transfer request to APHIS or CDC by mail, fax or email:

    Animal and Plant Health Inspection Service
    Agricultural Select Agent Program
    4700 River Road Unit 2, Mailstop 22, Cubicle 1A07
    Riverdale, MD 20737
    FAX: 301-734-3652
    E-mail: ASAP@aphis.usda.gov
    Centers for Disease Control and Prevention
    Division of Select Agents and Toxins
    1600 Clifton Road NE, Mailstop A-46
    Atlanta, GA 30333
    FAX: 404-718-2096
    Email: form2@cdc.gov

    Return to top

  7. Once submitted, when can I expect a decision regarding my transfer request?

    A written decision from APHIS or CDC is usually provided within 72 hours of receipt of the request. However, please note that an APHIS/CDC Form 2 with incomplete or inaccurate information may delay a decision concerning your request.

    Return to top

  8. How long is a transfer authorization from the Federal Select Agent Program valid?

    Approval of the transfer of a select agent and toxin is valid for 30 days from the date of authorization. This means that the transfer of the select agent or toxin must be completed before expiration of the 30 day period. Additionally, approval of a transfer becomes void should there be a change in any of the conditions upon which the approval was based (e.g., change in the certificate of registration for the sender or recipient or change in the application for transfer). Each transfer authorization number is valid for only one transfer of select agents or toxins during the 30 day period.

    Return to top

  9. We received authorization to transfer select agents to a registered entity. Can we ship multiple packages using the same transfer authorization number over the next 30 days?

    It depends. Each transfer authorization number is valid for only one transfer of select agents or toxins during the 30-day period. Therefore, multiple shipments occurring on different days would require separate authorizations from the Federal Select Agent Program. Large shipments that include multiple packages of select agents shipped on the same day can be shipped under the same transfer authorization number. Tracking information for each package of the large shipment needs to be provided on the APHIS/CDC Form 2.

    Return to top

  10. Is a non-registered entity allowed to receive select agents?

    No, within the United States (U.S.), only entities that are registered with the Federal Select Agent Program are allowed to receive agents that have been identified as select agents. This includes the importation of select agents from outside the U.S.

    Return to top

  11. What are the requirements for importation of a select agent or toxin into the United States?

    A CDC import permit is not required for an item if it is a select agent or toxin listed in 42 CFR Part 73.3 and 73.4 and its importation has been authorized in accordance with 42 CFR 73.16 or 9 CFR 121.16 for transfers.

    Return to top

  12. Is a transfer authorization from the Federal Select Agent Program required to export a select agent or toxin to a foreign country outside of the United States?

    No, however; the Department of Commerce regulates the exportation of a wide variety of etiologic agents of human, plant and animal disease and may require an export license. Information may be obtained by calling the DOC Bureau of Export Administration at (202) 482-4811, or at: http://www.access.gpo.gov/bis/index.html or http://www.bis.doc.gov/.

    Return to top

  13. Is a transfer authorization from Federal Select Agent Program needed to transfer a presumptive select agent or toxin identified in a clinical/diagnostic laboratory specimen?

    Anyone may send a presumptive select agent to a reference laboratory for confirmation without a transfer authorization from Federal Select Agent Program. However, after identity of the select agent or toxin is confirmed, a non-registered entity would be required to either destroy the specimen (diagnostic sample containing the isolate) or any isolates, or transfer it to an entity registered for that select agent or toxin. That transfer must first be authorized by either Federal Select Agent Program. To initiate the transfer process, contact a registered entity to arrange for transfer of your sample. If you need assistance locating a registered entity, contact APHIS ( phone: 301-851-3300 (option 1); fax: 301-734-3652) or CDC (phone: 404-718-2000; fax: 404-718-2096). For further guidance regarding reporting requirements for the identification of a select agent or toxin contained in a clinical/diagnostic laboratory specimen, please refer to: http://www.selectagents.gov/CDForm.html.

    Return to top

  14. Is a transfer authorization from Federal Select Agent Program needed to transfer a select agent or toxin that is contained in a specimen for proficiency testing?

    No, a sponsor/sender may send a select agent or toxin that is contained in a specimen for proficiency testing to a recipient without obtaining prior authorization from the Federal Select Agent Program provided that, at least seven calendar days prior to the transfer, the sponsor/sender send the Federal Select Agent Program a written report that includes the select agent or toxin to be transferred and the name and address of the recipient. For further guidance on reporting the identification of a select agent or toxin contained in a proficiency test, please refer to: http://www.selectagents.gov/CDForm.html.

    Return to top

  15. What should I do if a delivery exception occurs?

    A delivery exception occurs when a shipment is held at FedEx or returned to the shipper due to inadequate paperwork. If this occurs, please notify the Federal Select Agent Program and the recipient entity immediately. The notification should include the following:

    • New tracking number(s)
    • The reason and needed action associated with the delivery exception
    • Expected new date of arrival

    Note: A copy of an updated Section 2 of APHIS/CDC Form 2 must be submitted to the Federal Select Agent Program and the recipient prior to delivery. Please ensure blocks #34 and #37 are updated accordingly.

    Once the delivery exception package is delivered, the recipient must:

    • Ensure that the expected shipment was properly packaged, labeled, and shipped in accordance with all federal regulations.
    • Ensure that the shipment information (example: updated tracking number(s)) matches the information documented in the updated Section 2 of the APHIS/CDC Form 2.

    Return to top

  16. Is a transfer authorization from the Federal Select Agent Program required to transfer select agents or toxins identified from clinical/diagnostic specimens being sent for susceptibility testing?

    Yes, prior authorization from the Federal Select Agent Program is required for the transfer of the identified select agent(s) or toxin(s) being sent for susceptibility testing.

  4. After a transfer authorization is received from Federal Select Agent Program, what is required of the sender that wants to ship a select agent or toxin?

    The sender must:

    • Notify the Recipient of the expected shipment and document this notification in Section 2 of the form.
    • Ensure the material is properly packaged, labeled, and shipped in accordance with all federal regulations.
    • Ensure that the individual's information and description of the package are documented in Section 2 of the form.
    • Send APHIS or CDC a copy of the completed APHIS/CDC Form 2 (Sections 1 and 2) prior to shipment and include a copy with the select agent package.
    • In the case of an import shipment, the sending entity should notify the recipient entity with all relevant shipping information including the expected shipment date arrival, which the recipient entity should then forward to APHIS/CDC.

    Return to top

  5. What does the Recipient need to do upon receipt of the select agent shipment?

    • First, confirm that all the select agents and toxins listed on Section 2 of the form were received. Document any discrepancies and notify the sender and APHIS or CDC. If it is determined that there was a theft or loss during packaging or in transit, immediately contact APHIS (phone: 301-851-3300 (option 1); fax: 301-734-3652) or CDC (phone: 404-718-2000; fax: 404-718-2096) and submit APHIS/CDC Form 3 "Report of Theft, Loss or Release of Select Agents and Toxins." More information about reporting a theft or loss of a select agent or toxin is available at: www.selectagents.gov/TLRForm.html. If it is determined that the discrepancy is due to an administrative error, send an explanation of the error and a corrected APHIS/CDC Form 2 to APHIS or CDC. Please note that all records associated with a transfer should be kept for three years.
    • Inspect the package to verify that it is not damaged or leaking and that the material was packaged, labeled and shipped in accordance with federal regulations. If the package is received damaged or leaking to the extent that a release of the select agent or toxin may have occurred, immediately contact APHIS (phone: 301-851-3300 (option 1); fax: 301-734-3652) or CDC (phone: 404-718-2000; fax: 404-718-2096) and submit APHIS/CDC Form 3 "Report of Theft, Loss or Release of Select Agents and Toxins." More information about reporting a release of a select agent or toxin is available at: www.selectagents.gov/TLRForm.html.

General questions about transport of select agents and toxins

  1. What are some of the specific measures required to ensure that infectious substances are shipped safely?

    Department of Transportation Hazardous Materials Regulations (49 CFR Parts 171-180)

    The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has specific requirements for transporting infectious substances safely by motor vehicle, railcar, vessel, and aircraft. These requirements must be followed by domestic and international shippers and carriers. They also contain provisions on how to apply international regulations for hazardous materials. PHMSA's requirements for infectious substances are outlined below and explained in detail in the Department of Transportation (DOT) publication, "Transporting Infectious Substances Safely." This document is available at: phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/Transporting_Infectious_Substances_brochure.pdf.

    Category A Infectious Substances

    Category A infectious substances are capable of causing permanent disability, life threatening or fatal disease to humans or animals when exposure to them occurs. Category A infectious substances have two shipping names: "Infectious substances, affecting humans (UN 2814)" or "Infectious substances, affecting animals (UN 2900)." Examples of Category A substances can be found in the DOT publication "Transporting Infectious Substances Safely." This document is available at: phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/Transporting_Infectious_Substances_brochure.pdf.

    Packaging of Category A Infectious Substances

    Category A infectious substances must be shipped in a triple package that consists of a watertight primary receptacle or receptacles; a watertight secondary packaging (for liquid materials, the secondary packaging must contain absorbent material in sufficient quantities to absorb the entire contents of the primary receptacles); and a rigid outer packaging which must be of adequate strength for its capacity, mass, and intended use. Page 29 of the DOT " Transporting Infectious Substances Safely " ( https://hazmatonline.phmsa.dot.gov/services/publication_documents/Transporting Infectious Substances Safely.pdf) document provides a diagram of how to properly package a Category A infectious substance. The maximum quantity of Category A infectious substance that can be shipped by air in one package is 4 L or 4 kg. The maximum allowable quantity on passenger aircraft is 50 ml or 50 g.

    Labeling of Category A Infectious Substances

    The outer container of all Category A infectious substance packages must display the following on one side of the package:

    • Sender's name and address
    • Recipient's name and address
    • Infectious substance label
    • Proper shipping name, UN number, and net quantity of infectious substance
    • Name and telephone number of person responsible for shipment
    • Cargo Aircraft Only label when shipping over 50 ml or 50 g
    • Class 9 label, including UN 1845, and net weight if packaged with dry ice and identified as Carbon Dioxide, solid

    Category B Infectious Substances

    Category B infectious substances are infectious substances not in a form generally capable of causing permanent disability or life-threatening or fatal disease in otherwise healthy humans or animals when exposure to it occurs. This includes Category B infectious substances transported for diagnostic or investigational purposes. Category B infectious substances have the proper shipping name "Biological Substance, Category B" and the identification number UN 3373.

    Packaging of Category B Infectious Substances

    Category B infectious substances must be shipped in a triple package consisting of a leak proof primary receptacle or receptacles; leak proof secondary packaging (for liquid materials, the secondary packaging must contain absorbent material in sufficient quantities to absorb the entire contents of the primary receptacles); and rigid outer packaging. Page 31 of the DOT " Transporting Infectious Substances Safely " ( https://hazmatonline.phmsa.dot.gov/services/publication_documents/Transporting Infectious Substances Safely.pdf ) document provides a diagram of how to properly package a Category B infectious substance. The maximum quantity for a primary receptacle is 500 ml or 500g and outer packaging must not contain more than 4 L or 4 kg.

    Labeling of Category B Infectious Substances

    The outer container of all Category B infectious substance packages must display the following on one side of the package:

    • Sender's name and address
    • Recipient's name and address
    • The words "Biological Substance, Category B"
    • UN 3373 label
    • Class 9 label, including UN 1845, and net weight if packaged with dry ice and identified as Carbon Dioxide, solid

    Diagnostic/Clinical Specimens

    Any human or animal material including, but not limited to, excreta, secreta, blood and its components, tissue and tissue fluids, being transported for diagnostic or investigational purposes, but excluding live infected animals. Diagnostic specimens are usually assigned to UN3373, unless the source patient or animal has or may have a serious human or animal disease which can be readily transmitted form one individual to another, directly or indirectly and for which effective treatment and preventable measures are not usually available in which case they must be assigned to UN2814 or UN 2900 and shipped as a Category A infectious substance.

    Packaging of Diagnostic/Clinical Specimens

    Diagnostic and clinical specimens must be shipped in a triple package consisting of a leak proof primary receptacle or receptacles; leak proof secondary packaging (for liquid materials, the secondary packaging must contain absorbent material in sufficient quantities to absorb the entire contents of the primary receptacles); and rigid outer packaging. Page 31 of the DOT publication " Transporting Infectious Substances Safely " ( https://hazmatonline.phmsa.dot.gov/services/publication_documents/Transporting Infectious Substances Safely.pdf ) document provides a diagram of how to properly package a Diagnostic Specimen. The maximum quantity for a primary receptacle is 500 ml or 500g and outer packaging must not contain more than 4 L or 4 kg.

    Labeling of Diagnostic/Clinical Specimens

    The outer container of all diagnostic/clinical specimen packages must display the following on one side of the package:

    • Sender's name and address
    • Recipient's name and address
    • The words "Biological Substance, Category B"
    • UN 3373 label
    • Class 9 label, including UN 1845, and net weight if packaged with dry ice and identified as Carbon Dioxide, solid

    Biological Products

    The DOT regulations (49 CFR 173.134(a)(2), http://edocket.access.gpo.gov/cfr_2007/octqtr/pdf/49cfr173.134.pdf ) describe a biological product as a virus, therapeutic serum, toxin, antitoxin, vaccine, blood, blood component or derivative, allergenic product, or analogous product, or arsphenamine or derivative of arsphenamine (or any other trivalent arsenic compound) applicable to the prevention, treatment, or cure of a disease or condition of human beings or animals. These are products derived from living organisms that are manufactured and distributed in accordance with special licensing requirements, and are used either for prevention, treatment or diagnosis of disease in human or animals, or for development, experimental or investigational purpose. They include, but are not limited to, finished or unfinished products such as vaccines and diagnostic products.

    Packaging, Labeling and Shipping of Biological Materials

    A biological product that is suspected to contain a pathogen that meets the definition of a Category A or B infectious substance must be assigned to UN 2814, UN 2900, or UN 3373 as appropriate and shipped and packaging in accordance with those criteria.

    Biological products transported for final packaging, distribution, or uses by medical professionals are not subject to shipping regulations.

    Genetically Modified Organisms and Micro-organisms

    These are microorganisms and organisms in which genetic material has been purposely altered through genetic engineering in a way that does not occur naturally. They are divided into the following categories:

    1. Genetically modified microorganisms, which meet the definition of an infectious agent, must be classified as Category A or Category B and assigned UN 2814 or UN 2900.
    2. Animals, which contain or are contaminated with genetically modified microorganisms or organisms that meet the definition of an infectious substance must not be transported by air unless exempted by the States concerned.
    3. Genetically modified organisms, which are known or suspected to be dangerous to humans, animals or the environment, must not be transported by air unless exempted by the States concerned.
    4. Except when authorized for unconditional use by the states of origin, transit, and destination, genetically modified microorganisms which do not meet the definition of infectious substances but which are capable of altering animals, plants or microbiological substances in a way which is not normally the result of natural reproduction must be classified as Class 9.

    Genetically modified organisms, which do not meet the definition of an infectious substance and which are not otherwise included under (a) to (d) above, are not subject to these regulations.

    Packaging of Genetically Modified Organisms and Micro-organisms

    These materials must be packaged in the same manner as Category B infectious substances except there are no testing requirements for the packaging. The maximum allowable quantity per primary receptacle is 100 ml or 100 g. There is no maximum net quantity per package.

    Labeling of Genetically Modified Organisms and Micro-organisms

    The outer container of genetically modified organisms and micro-organisms assigned to UN 3245 must have the following labels:

    • Sender's name and address
    • Recipient's name and address
    • Class 9 label

    Definitions of Watertight/Leakproof

    Although the PHMSA's Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180), do not specifically define the terms "watertight" and "leakproof," these terms under the HMR essentially mean the receptacles and packaging are designed and constructed in a manner that does not permit a liquid material to enter or escape. These regulations are available electronically at the U.S. Government Printing Office's website at: http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?sid=585c275ee19254ba07625d8c92fe925f&c=ecfr&tpl=/ecfrbrowse/Title49/49cfrv2_02.tpl .

  2. What happens if a package containing a select agent or toxin is lost or damaged during shipment?

    Requirements for All Infectious Substances

    Infectious substanceThe DOT regulations (49 CFR 171.15 and 171.16) require each person in physical possession of a hazardous material, including an infectious substance, to report specific types of transportation incidents that involve these materials. Immediate reporting by telephone to the National Response Center at 1-800-424-8802 is required for incidents where fire, breakage, spillage, or suspected contamination occurs that involves the shipment of infectious substances other than a patient specimen or regulated medical waste ( See 49 CFR 171.15(b)(3)). In addition, a written report to DOT is required within 30 days of the discovery of the incident for any unintentional release of hazardous material from a packaging during transportation, including those covered under 49 CFR 171.15 ( See 49 CFR 171.16(a)). DOT regulations also require packages that contain infectious substances to be accompanied by several forms of hazard communication, as applicable, as well as labeled to indicate the infectious hazard ( See 49 CFR 172.432 for a depiction of the required label). This label currently includes a statement for reporting a damaged package.

    The WHO "Guidance on Regulations for the Transport of Infectious Substances," January 2009, available at http://www.who.int/csr/resources/publications/biosafety/WHO_HSE_EPR_2008_10/en/, also provides specific recommended procedures for spill cleanup. This guidance is available to the agencies that govern land, vessel, and air shipments. The recommended procedures reflect those contained in the WHO Laboratory Biosafety Manual, Third Edition, 2004. The manual can be found at: http://www.who.int/csr/resources/publications/biosafety/WHO_CDS_CSR_LYO_2004_11/en/.

    Special Requirements for Select Agents

    If a package containing select agents has not been received within 48 hours after the expected delivery time or has been damaged to the extent that a release of a select agent may have occurred, the recipient must immediately report this incident to CDC or APHIS. In addition to the initial reporting, the entity must follow up with a written report (APHIS/CDC Form 3 - Report of Theft, Loss, or Release of Select Agents and Toxins) within 7 calendar days of the incident. Specific guidance on this form is available at: http://www.selectagents.gov/TLRForm.html. Additional guidance on specific scenarios which would require an entity to report a theft, loss, or release of a select agent to CDC or APHIS is available at: http://www.selectagent.gov/resources/CompleteTHEFT%20LOSS%20%20RELEASE%20guidance%20document%20June82010_FINAL.pdf. Upon receipt of the report of the incident, APHIS or CDC will review the report to determine the appropriate action, which could include requesting additional information, administrative action, inspection, and/or referral to the Federal Bureau of Investigation for further investigation. If there is a threat to the public, APHIS or CDC will notify the appropriate local, state, and federal agencies.
