Antibiotic Drug Warning to Dairies in Three States

Warning letters on March 25, March 28, and April 6 put dairy farms in California, Idaho and Wisconsin on notice about misuse of animal antibiotics.   

In each case, the U.S. Food and Drug Administration (FDA) said it turned to the testing USDA’s Food Safety and Inspection Service does on animal tissues after slaughter to determine what, if any, animal drug residues are still found in the meat.

The three antibiotics that FDA said turned up in tests of animals from these dairy farms were all common, and included:

— Flunixin, also known as flunixin meglumine, is a nonsteroidal anti-fammatory agent.

— Ampicillin is a beta-lactam antibiotic used for 50 years to treat bacterial infections.

— Sulfadimethoxine is a sulfonamide antibiotic.

In finding that residues of the drugs were at levels much higher than tolerance levels, FDA said each dairy was holding animals under conditions that were “so inadequate that medicated animals bearing potentially harmful drug residues are likely to enter the good supply.”

Each dairy farm was given 15 working days to inform FDA of the steps it is taking to bring its operations into compliance.

Here are the specific details:

Who: Van Es Dairy

What:  Flunixin in liver tissue

When: June 16, 2010

Where: Marsing, ID

How: A dairy cow sold for slaughter as food was found with 0.662 parts per million (ppm) of flunixin in the liver tissue.  The tolerance level is 0.125 ppm.

What: Ampicillin in uncooked edible tissues.

When: September 17, 2010

Where: Elkhart Lake, WS

How: A dairy cow was consigned for hauling to slaughter as food.  The presence of ampicillin at 0.33 ppm in the kidney was found.  The tolerance level is 0.01 ppm.

Who: Cache Creek Dairy

What: Sulfadimethoxine in the edible tissues

When: May 27, 2010

Where: Woodland, CA

    Antibiotics in our food is one of the hidden costs of feeding grain to ruminates… They’re built to digest cellulose, not starch. To feed them grains (assuming you want to keep them alive) requires you feed them antibiotics!

  • Hi, my name is Brian Drake from Drake Dairy, Inc. I with my dad and another partner, Omar, run the dairy. Each of us are personally on our farm 360 or more days per year. We (Jim, Omar, myself, and all our employes) treat our amimals with better care then most people would treat their own family. We love our cows and our job. When treating animals we follow according to lable in safety of the cow during her life and after for the safety in her meat. We apologize for any problem with this cow.
    P.S people have been growing and feeding corn for hundereds of years with no problems. Amimals are like people they get sick too, it’s just part of life.
