Reports of beef contaminated with pathogenic
E. coli 0157 seem to be almost commonplace in recent years. That’s not something I remember from my childhood. So what has changed? A recent
study at Kansas State University may hold part of the answer, and, surprisingly, one environmentally useful compound may be implicated.
Veterinary researchers looked at the connection between types of feed and bacterial loads. Cattle fed with distilled grain from
ethanol plants had more
E. coli 0157 in their digestive systems. In fact, they had about twice the level found in other cattle. The mechanism is not yet understood - researchers suggest that it may be due to digestive changes or increased bacterial nutrition, for example. The details will form the basis for future investigations.
Despite being naturally occurring, these particular bacteria are associated with
health problems in humans. Consumption of undercooked meat, unpasteurized dairy products, and produce contaminated with manure are all pathways for human infection. From apple juice to lettuce, carrots to raspberries, hamburgers to raw cheese, there are many ways for people to run afoul of this pathogen.You can find the entire article here
