New testing combats drug residues

The USDA Food Safety and Inspection Service (FSIS) recently implemented new sampling and analytic procedures for meat, poultry and eggs.1 These new procedures and tests put an even greater focus on combating drug residues. Here’s what you need to know:

  • FSIS increased the number of samples taken and the number of tests run on each sample. The new sampling and testing procedures will allow FSIS to screen for 52 compounds per sample, testing for both antibiotic and nonantibiotic residues.
  • FSIS emphasized there is no tolerance for meat residues from drugs either not approved for cattle or not approved for lactating dairy cattle. This means that any residue found from a non-lactating medicine in a lactating cow (20 months or older) will be a violation.
  • FSIS also stressed that no quantities of that are not labeled for use in any cattle.

The dairy industry has been making progress reducing the number of drug residues in recent years. The additional tests will help us find more ways to improve food production. As food providers, we have a responsibility to protect the food supply — meaning we need to ensure the food we provide is safe and of the highest quality for consumers. Drug residues in meat or milk damage the public’s confidence in our ability to provide safe food.

Talk with your veterinarian to learn more about which drugs are now under FSIS’s no-tolerance policy. If you’ve been using them, your veterinarian can help you write protocols that include approved drugs and labeled directions. Also, work with your veterinarian to develop an effective, easy record-keeping system that also will help combat drug residues.
