"Our leading anti-infective brands are effective treatments, and when they are used according to label indications, producers and veterinarians will not have to worry about a violative, ceftiofur residue in milk or meat. That"s our guarantee. No other animal health company makes that kind of commitment to help the industry avoid violative residues."

With the Residue Free Guarantee, in the unlikely event a producer experiences a violative, ceftiofur meat or milk drug residue after using one of these products, he or she will be compensated for the beef market value of the animal or the tanker of milk at fair market value. To qualify for the guarantee, the product must have been purchased from a Pfizer Animal Health-approved supplier and used according to label indications. Documentation of purchase and adequate treatment records also must be maintained.

The educational website,, supports the Residue Free Guarantee by providing producers and veterinarians with information on how to help prevent milk and meat residues. Visitors will find thought-provoking, action-oriented videos about the causes of violative drug residues and tips for getting started on a drug residue prevention plan. In addition, a Residue Risk Assessment tool helps producers evaluate the potential risks of a violative milk or meat residue on their dairy.

"Pfizer Animal Health is committed to the health and profitability of dairy operations and the quality and safety of the food our industry produces," says Dr. Lormore.
