[QUOTE="TexasBred, post: 423066, member: 6897"] Since these are dairy cattle and apparently were tested at a slaughter house you'd have to assume the were sold as "packers". Antibiotics are most common drug used in dairy animals and are probably what USDA found. Infusion of antibiotics into the teat end for treatment of mastitis as well as possible injection (yes IM injection) would be most likely cause of the drug residue. Although these drugs show a "milk withdrawl time" many do not give you a withdrawal time on meat. You just have to be very very careful and hope you've held them out of the food chain long enough for all meds. to be out of the system. There are "on farm" tests for antibiotics in milk, but unfortunately I know of none for meat, but you'd assume that as long as the milk test positive for drugs the meat would also.
