A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. The use of antibiotics in the husbandry of livestock includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment (prophylaxis).
Antibiotics are routinely given to livestock, which account for 70% of the antibiotic use in the United States. [18] This practice contributes to the rise of antibiotic-resistant bacteria. [19] Antibiotic resistance is a naturally occurring phenomenon throughout the world due to the overuse and/or inappropriate use of antibiotics. [20]
In 1998, the EU banned feeding animals antibiotics that were found to be valuable for human health. Furthermore, in 2006 the EU banned all drugs for livestock that were used for growth promotion purposes. As a result of these bans, the levels of antibiotic resistance in animal products and within the human population showed a decrease. [93] [94]
In the worst-case scenario, antimicrobial resistance in livestock could jeopardize the food supply of more than 2 billion people. Opinion - ‘Superbugs’ could devastate livestock globally Skip ...
This is especially important, as antibiotics cannot be successful in antibiotic resistant bacteria. And an increased use of antibiotics further promotes the evolution of antibiotic resistant bacteria. And specifically in MRSA ST398, the link between antibiotic use in livestock and the emergence of MRSA ST398 is not yet fully understood.

[3] [4] [5] While the benefits of subtherapeutic antibiotic administration are well-documented, there is much concern and debate regarding the development of bacterial antibiotic resistance associated with their use. This is a specific case of the more general practice of antibiotic use in livestock.
A 2011 study reported 47% of the meat and poultry sold in surveyed U.S. grocery stores was contaminated with S. aureus, and of those 5–24.4% of the total were resistant to at least three classes of antibiotics. "Now we need to determine what this means in terms of risk to the consumer," said Dr. Keim, a co-author of the paper. [5]
