FDA will soon begin a milk sampling program aimed at approximately 900 dairies across the US that have had a meat residue violation in the past three years. These dairies will be randomly selected from a national pool of 1600-1800 dairies. The FDA is concerned that operations that have marketed an animal with a confirmed meat residue may be at higher risk of selling milk with violative residues, particularly with non beta-lactam (beta-lactams = penicillin, ceftiofur) drugs. Of particular interest are the anti-inflammatory drug flunixin meglumine (Banamine®) and the sulfa family of drugs.

Since the announcement of FDA’s intent, dairy organizations and co-ops have provided information to producers, and many veterinarians and dairy producers have been looking at their treatment protocols and withholding times more closely. However, there are still some questions producers have about the process and the consequences of the testing program.  And, probably more important is: What are the reasons for the residues seen and what should we look for to tighten up our drug use procedures?

The Washington State Department of Agriculture and Washington State University Extension are sponsoring 3 meetings throughout the state for dairy producers and veterinarians to help address this issue. The meetings will start at 11:00am and lunch, sponsored by Pfizer Animal Health and Northwest Dairy Association, will be provided on the following dates:

§  Wednesday -- March 30, 2011 - Bon Vino’s Bistro, 122 N. 16th St, Sunnyside, WA

§  Thursday -- March 31, 2011 - Kit Carson Restaurant, 107 Interstate Ave, Chehalis, WA

§  Friday -- April 1, 2011 - Fairway Café, 1726 Front St, Lynden, WA

*Meetings will begin promptly at 11:00 AM at each location. Please come!


At each of these three meetings, we invite dairy producers and veterinarians to discuss the following:

1.     What are the facts about the FDA’s concern and what is the proposed process for milk testing? 

Claudia Coles, Food Safety Program Manager, and Dr. Paul Kohrs, Assistant State Veterinarian, WSDA

2.     What are the primary reasons for a residue from specific drugs and how does that inform prevention strategies?

Dr. Dale Moore, Director, Veterinary Medicine Extension, WSU

3.     How can I reduce disease and treatments, determine if treatments are working, and better track drug withdrawal times?  Your cows have the answers; learn how to better understand what they are saying.  Dr. John Wenz, Assistant Professor, Field Disease Investigation Unit, WSU


4.     What are the current requirements for handling non-ambulatory cows, what role do they play in food safety, and what are some of the reasons for down cows?

Dr. Paul Kohrs, Assistant State Veterinarian, WSDA

Materials distributed:

* New “Milk and Dairy Beef Residue Prevention” booklet and
  “Animal Care Manual/Quick Reference Guide”

* CD from Colorado State on Downer cows, in English and Spanish
