Today’s animal-health products that are used in food animals undergo rigorous safety testing. However, there are occasions when veterinarians or producers may suspect an adverse reaction is due to a vaccine or drug. For this reason, both producers and veterinarians should record serial numbers and/or the lot number of each product used, says M.G. Scroggs, a swine veterinarian with Merial. Scroggs also suggests that producers use an animal map describing the location of each injection and/or product used.

“Should a negative reaction occur, by using an animal map the specific product causing the problem can be identified,” he says. “Thus, once the product causing the problem has been identified, with the knowledge of the serial number and/or lot number, the manufacturer can check its records for any other possible reactions with that specific product.”

Scroggs says if a product is drop-shipped to the producer, it is his or her responsibility to record appropriate information such as serial numbers, lot numbers and so forth. “In all reality, the producer should keep these records since it involves their animals,” says Scroggs. “This is practicing good management, and it’s a way to assure the public that our food is safe.”
