Please see the attached memo from Dr. Amar Patil, DVM, MVSc, Ph.D., Diplomate ACVM, Director of the Division of Animal Health/State Veterinarian: Federal Order Influenza A in Cattle Memo April 27, 2024
This order includes specific requirements regarding the testing of lactating cows for Bovine Influenza A Virus (H5N1) before interstate movement. New Jersey dairy producers needing pre-movement testing should contact their attending veterinarian to arrange for sample collection, which must occur no more than seven (7) days before interstate movement. The test sample required from lactating dairy cattle is milk/udder secretions from each quarter per individual cow (ensure each quarter is sampled, as there have been reports of only one quarter having the virus), which is then combined into one sample tube (a total volume of 3-10 ml of milk per animal should be submitted). The samples can be submitted to the NJDA Animal Health Diagnostic Laboratory (AHDL), a USDA-approved National Animal Health Laboratory Network (NAHLN) laboratory. Samples submitted to the NJDA AHDL will be tested by real-time polymerase chain reaction (PCR) assay for influenza A, which will be completed at no cost to the producers/veterinarians. Influenza A testing for interstate dairy cattle movement is an additional requirement to the preexisting livestock importation regulations in New Jersey, N.J.A.C. 2:3 Livestock and Poultry Importation. Persons moving dairy cattle are reminded that these requirements are in addition to the official identification, certificate of veterinary inspection (CVI), and testing requirements conventionally required for cattle movement. Please consult the receiving state to confirm all other interstate movement requirements prior to affecting an animal’s movement.
Listed below are particularly important aspects of the Federal Order and USDA guidance.
Mandatory Testing for Interstate Movement of Dairy Cattle:
- Prior to interstate movement, non-clinical lactating dairy cows are required to receive a negative test for Influenza A virus at an approved National Animal Health Laboratory Network (NAHLN) laboratory in addition to meeting the importing state’s testing requirements and a certificate of veterinary inspection (CVI).
- Non-clinical lactating dairy cows moving interstate direct to slaughter do not require influenza A testing but require a certificate of veterinary inspection (CVI).
- Non-clinical lactating dairy cows moving interstate through auction markets in New Jersey to out-of-state slaughter do not require influenza A testing but require a certificate of veterinary inspection (CVI).
- Non-clinical lactating dairy cows moving interstate to auction market in another state require influenza A testing and a certificate of veterinary inspection.
- Nonlactating dairy cattle, including bull calves, dry cows, and heifers; and beef cattle are exempt from Influenza A testing for interstate movement.
- Movement tests are valid for seven (7) days from the date of sample collection.
- For imported cattle attending a New Jersey Fair/Show, Influenza A testing is required for lactating dairy cattle in addition to meeting requirements in the 2024 fair and show letter.
- Owners of herds in which dairy cattle test positive for interstate movement will be required to provide epidemiological information, including animal movement tracing.
- Sick cattle are not eligible for movement. Dairy cattle herds that have tested positive for influenza A must wait 30 days and retest negative to be eligible for movement.
Mandatory Reporting: Laboratories and state veterinarians must report positive Influenza A detection diagnostic results in livestock to USDA APHIS.
