food recall

Tainted, chopped romaine lettuce grown in Yuma, Ariz., is the source of an E. coli outbreak that has sickened at least 53 people in 16 states, according to the Centers for Disease Control and Prevention.

Any dumpster diver can tell you: Grocery stores throw away a lot of food.

But food discarded off the shelf is just one way that grub gets trashed. There's other waste along a grocery store's supply chain —rejected crops at farms, for example — that's often overlooked. So The Center for Biological Diversity and The "Ugly" Fruit and Veg Campaign recently asked the 10 largest U.S. supermarkets how they handle food waste, and gave each store's efforts a letter grade.

Procter & Gamble is voluntarily recalling some of its dry dog and cat foods. The company says they may be contaminated with Salmonella. The affected brands include various types of Iams and Eukanuba.

In a release, P&G says:

These lots were distributed in the United States and represent roughly one-tenth of one percent (0.1%) of annual production. No Salmonella-related illnesses have been reported to date in association with these product lots.
