'Superbugs' not related to farming, AVMA official says

Christine Hoang, DVM, assistant director of Scientific Activities at the American Veterinary Medical Association (AVMA) and an expert on antimicrobial resistance, shed light on the use of antibiotics in livestock during a recent U.S. Farmers & Ranchers Alliance (USFRA) panel discussion.

One of the most common criticisms about the use of antibiotics on farms is that it might lead to the creation of resistant human pathogens, such as MRSA and C. difficile. Hoang said these fears are unfounded because studies have shown that these “superbugs” are not related to farming.

“They’re human-related resistant infections that are in no way related to antibiotic use in livestock production,” she said.

The prevention of antibiotic resistance in humans is one of the reasons veterinarians support the continued use of preventive applications of antibiotics in the practice of medicine on farms. Hoang explained that waiting until an animal is sick to use antibiotics could, in fact, make it more likely these “superbugs” will develop, because veterinarians will be forced to treat sick animals with more powerful antibiotics that are more commonly used in human medicine and use them at higher doses.

Hoang explained that there are other benefits of preventive applications of antibiotics on farms. Preventive antibiotic use reduces the transmission of food borne illnesses into our food supply, and there are substantial animal welfare benefits.

“Because you are preventing the disease before it occurs, there is benefit to the animals because they are not getting sick and suffering,” she said.

Hoang also explained the benefits of including antibiotics in animal feed, which is something that has drawn criticism in the media. Including preventive medications in livestock feed is simply safer and more humane, reducing the need for injections or other individualized treatments of animals.

Good information that reinforces previous findings. BUT, this message isn't getting through to the consumers and general public. THE Science is being drowned-out and shouted-down by US congress, via Rep Slaughter and her merry band of mythos makers. Again, we see this in the Farm Press but nowhere else. So, what good does it do us? Our customers are being sold a bill of goods that claims we, their food providers, are Killing Them with super-bugs and they react as you would expect panic driven people to react - badly. While anti-farm, anti-livestock advocates pull us toward Banning all Antibiotics in livestock, the grossly misinformed consumer pushes and cheers. Real Science is great, but it doesn't do us any good if we are the only ones who know and understand it. Slapping ourselves on the back, plus $3.50, will buy you a starbucks and that's all.
