"Brian Sandle" wrote in message snip It also advocates removal of antibiotic resistance genes from GM constructs used in the production of food, but falls short of calling for their removal in animal feed, even though there is growing evidence that bacteria can pass from farm animals to human beings - E. coli 0157 is a well known example. There a large number of diseases that are transmittable from farm animals to man. Anthrax, bruculosis, tuberculosis, leptospiris, a half dozen parasites and flu often passes from birds to pigs to man just to name a few. E. coli O157 is not normally transmitted to people unless they are raised in isolation from livestock a practice that has only been common in the last 50 years. Any one that is around livestock on a regular basis does not catch it. If they are able to build resistance. Maybe it used to be part of infant mortality. We feed the livestock a lot more antibiotics as growth promoters that would cause resistance more than any possible unproved transfer from feed. We have been doing for 50 years with out a problem and they still are antsy about it. You can find antibiotic resistant bacteria in the most remote places of the world. If we were going to create an antibiotic resistant e. coli O157 the antibioses we feed cattle are lot more worrisome. The antibiotics provide the selective force and the bacteria can pick up resistance genes from the food, since they are constantly present. |
