Antimicrobial Residues and Resistance: Understanding and Managing Drug Usage on Dairy Farms

Dr. Pamela Ruegg, Dairy Science Department, University of Wisconsin-Madison
The objective of this paper is to review data about the relationship between antimicrobial resistance and the use of antimicrobials in dairy cattle with emphasis on antimicrobials used for treatment of mastitis.

Drug Residue Déjà Vu: Avoiding Residues in Milk and Cull Dairy Cows

Dr. Pamela Ruegg, Dairy Science Department, University of Wisconsin-Madison
While mastitis is the most common disease of adult dairy cows and accounts for most usage of antibiotics cows are also treated for other infectious diseases, including respiratory and uterine infections and infectious foot disease. The risk of antimicrobial residues in meat and milk is well known and if the focus of intensive regulatory processes. The purpose of this paper is to review important data about how antimicrobials can be safely and judiciously used on dairy farms.

Phenotypic antimicrobial susceptibility and occurrence of selected resistance genes in gram-positive mastitis pathogens isolated from Wisconsin dairy cows

P.L. Ruegg, L. Oliveira, W. Jin, and O. Okwumabua
Determined phenotypic susceptibility and presence of selected antimicrobial resistance genes from staphylococci, streptococci, and streptococcal-like organisms recovered from cases of clinical mastitis occurring in cows on large Wisconsin farms.

UW Milk Quality is back with a new video series: Making Responsible Choices about Antibiotic Drug Use. As consumer consciousness about the food system increases, so do the concerns over antibiotic drug use and the potential of drug residue in the dairy industry.

1First episode: Understanding the Role of the VeterinarianSlide1
In this episode, Dr. Pamela Ruegg speaks of the importance for producers and dairy professionals to understand these concerns and make sure that drugs are used responsibly. Ruegg explains what the Veterinarian-Client-Patient Relationship is and how to establish one with your veterinarian.
 
 
 
 
 
 
 
 
4Next episode: Allowable Drug Usage in Dairy CowsSlide1
Treatment and control of disease in your dairy herd can be confusing, especially when trying to keep up-to-date on federal drug regulation. Knowing the right definitions and allowable types of drug usage on dairy farms are important to ensure your animals receive appropriate care and that food produced from those animals with be safe for human consumption. In this episode, Dr. Pamela Ruegg explains the different classes of allowable (and prohibited) drug usage on U.S. dairy farms.
 
 
 
 
 
 
1Final episode: Reducing the Risk of Residues in Milk and MeatSlide1
The occurrence of antibiotic residues found in milk and meat in the dairy industry is rare. Though rarely detected, mistakes still occasionally occur. UW Milk Quality’s Dr. Pamela Ruegg reviews the practical aspects that will help reduce that risk in this final episode of the series.
