Simply stated, massive and dangerous microbial contamination events will become a growing threat to a food supply system already fraught with potential Achille's heels. I hadn't said that. This one, Salmonella typhimurium DT104, is resistant to at least five antibiotics including the former powerhouses ampicillin, chloramphenicol, streptomycin, sulfonamides and tetracycline. It kills cattle AND people. The only antibiotics the bug has not shown resistance to here in the U.S. yet is a new class of drugs called fluoroquinolones.
Bacteria mutate quickly.
All you need to do is expose them to the agent you want to create resistance to and, bingo, Nature cooperates. When that happens with DT104, we'll have nothing left to fight it. Animals and people will die. DT104 is now epidemic in England. It has also swept through Denmark, Germany, and Wales.
