Drug Residues In Meat And Dairy Products -Should We Be Concerned?

Drug Residues In Meat And Dairy Products

Although much of the alarm over the use of antibiotics on livestock focuses on its contribution to bacterial resistance, the presence of drug residues and other chemicals in meat and dairy products is causing concern.

A survey on veterinary drug use and residues in milk in Hyderabad.

A survey on veterinary drug use and residues in milk was carried out in Hyderabad (India) and surrounding suburban villages. Mastitis was the most common disease reported; oxytocin and oxytetracycline were frequently used in veterinary formulations. Of 205 milk samples analysed, 9% of market samples and 73% of individual animal milk samples contained oxytetracycline residues. None of the government dairy samples contained oxytetracycline residues. Maximum oxytetracycline consumption through milk was calculated to be 0.045 mg/kg bw/day. The levels ranged from 0.2 to 1.4 micrograms/ml in market milk samples and from 0.2 to 6.7 micrograms/ml in samples obtained from individual buffaloes. It was found that the oxytetracycline residues affect curd setting, the extent depending on the amount of residue.


Last year, the U.S. Food and Drug Administration issued 78 warning letters (up from nine in 2002) to livestock producers or brokers whose meat samples bore traces of illegal drugs or of residues that were illegally high.

Those numbers likely underestimate the problem, as the U.S. Department of Agriculture samples only a fraction of the animals slaughtered each year. The FDA enforces regulations on residues but said it doesn’t have the resources to inspect every facility connected with an animal found to be in violation.

Drug residues pose various risks to consumers. Penicillin, for example, can cause acute allergic reactions, and the drug flunixin can lead to gastrointestinal and kidney problems.

Drug residues have been found in pigs, veal calves and meat cattle, but the vast majority of residue violations were found in dairy cows sent to slaughter: 700 in 2010 and 475 in 2011. These animals make up less than 8 percent of all beef animals slaughtered but account for nearly 70 percent of all drug violations found in beef, mostly related to antibiotics and painkillers.
