| Why is it that physicians who care for humans worry about antibiotic resistance from overuse of antibiotics, but veterinarians are not at all concerned? The vast majority of antibiotics used in this country are given to animals who aren't even sick. The antibiotics are intended to promote growth and to prevent infections from occurring in factory farmed animals whose immune systems are compromised by the harsh conditions they live in. The practice of giving non-therapeutic antibiotics to livestock threatens the effectiveness of antibiotics in human medicine, yet the American Veterianary Medical Association has come out against a bill to ban 7 classes of antibiotics used in human medicine from non-therapeutic use in livestock. What gives?
Antibiotic resistant bacteria is not a future problem - it's a current problem. In addition to reports of MRSA on factory hog farms, I've also seen reports like this one from Bill Marler about antibiotic-resistant Salmonella:
Just in the last week, the reality (again) of antibiotic-resistant Salmonella Newport has surfaced (again), this time sickening dozens so far in several states, and leading to the recall of nearly a million pounds of tainted hamburger. This follows a recall of nearly a half a million pounds of Salmonella-tainted burger in Colorado after sickening several a month ago.
Of course, this is not the first time that antibiotic-resistant Salmonella has hitched a ride in hamburger - there were illnesses in 1999, and it was reported by the CDC in 2002 and a WARNING issued by FSIS in 2007. The New Hampshire Department of Health and Human Services has urged a strategy to combat multidrug-resistant (MDR) Salmonella in ground beef. The CDC, through NARMS has continued to raise concerns about the over-use of antibiotics in our food supply. And, there is clearly no question that these bugs are in the cows we get our milk and the meat that we eat.
The CDC has reported that Salmonella Newport is the third most common Salmonella serotype in the United States. During 1997 - 2001, the number of laboratory-confirmed Salmonella Newport infections reported to CDC increased from 1,584 (5%) of 34,608 reported Salmonella infections to 3,152 (10%) of 31,607 (CDC, unpublished data, 2002). The increasing number of Salmonella Newport infections in the United States appears to be associated with the emergence and rapid dissemination of multidrug-resistant strains of Salmonella Newport. Since 1996, NARMS has identified an increasing number of Salmonella Newport isolates that are resistant to at least nine of 17 antimicrobial agents tested: amoxicillin/clavulanate, ampicillin, cefoxitin, ceftiofur, cephalothin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline.
If you find this as concerning as I do, please contact your Representative and your Senators and ask them to support the Preservation of Antibiotics for Medical Treatment Act. |
