The following firms/individuals received warning letters for offering animals for slaughter that contained illegal drug residues:

  • George Kasbergen, Co-Owner, Spring Grove Dairy, Mira Loma, CA
  • Cornell Kasbergen, Co-Owner, Spring Grove Dairy, Tulare, CA
  • Wayne L. Jones, President, Jones Brothers Dairy, LLC, Mount Horeb, WI

These violations involved illegal residues of neomycin in a dairy cow, multiple residues of tilmicosin, penicillin, sulfadimethoxine, and gentamicin in steers, gentamicin in a calf, sulfamethazine in a bob veal calf, penicillin in a culled dairy cow, penicillin in a cow, and sulfadimethoxine in a dairy cow.

A warning letter was issued to John Tyson, Chairman of the Board and CEO, Tyson Foods, Springdale, AR, for violations related to 21 CFR Part 589.2000 - Animal Proteins Prohibited in Ruminant Feed. This regulation is intended to prevent the establishment and amplification of Bovine Spongiform Encephalopathy (BSE).

Violations included failure to label the organ slurry product with the required cautionary statement "Do Not Feed to Cattle or Other Ruminants". The FDA suggests the statement distinguished by different type size or color or other means of highlighting the statement so that it is easily noticed by a purchaser.

Doug Robertson, Owner, Equine Serum Products, Inc., Lamar, MO, received a warning letter for marketing and distributing the product "Cycle Pro Pregnant Mare Serum" without an approved New Animal Drug Application.
