Came across this article from the Consumerist (which in turn summarizes a New York Times article) about the ever present risk of E. Coli in US meats.  It talks about some of the cost-cutting measures taken by companies in the food industry, which includes using a variety of different sources for their meat and under-the-table dealings.

Unwritten agreements between some companies appear to stand in the way of ingredient testing. Many big slaughterhouses will sell only to grinders who agree not to test their shipments for E. coli, according to officials at two large grinding companies. Slaughterhouses fear that one grinder’s discovery of E. coli will set off a recall of ingredients they sold to others.

Really disturbing stuff.  Costco is applauded, however for their high standard and dilgent meat testing.  Definitely something to chew on (pun intended).  Makes me appreciate my flexitarian ways!
