There's a long article in Sunday's New York Times on palliative sedation. I've also listed some older stories on the subject and an educational site.

Aging, end-of-life, and death

Hard Choice for a Comfortable Death: Sedation, (The New York Times)
"Among those [end-of-life] choices is terminal sedation, a treatment that is already widely used, even as it vexes families and a profession whose paramount rule is to do no harm. Doctors who perform it say it is based on carefully thought-out ethical principles in which the goal is never to end someone's life, but only to make the patient more comfortable."

Last year it was tomatoes contaminated with Salmonella. Except not really. After the tomato industry lost $200 million, it turned out it wasn't tomatoes after all, but jalapeno and serrano peppers from Mexico. Tomatoes aren't off the hook though. There have been 12 Salmonella-contaminated tomato outbreaks since 1990 serious enough to involve multiple states.

In 2007 it was the bagged spinach food scare, also a Salmonella problem. In 2006, spinach contaminated with pathogenic E. coli was recalled. That was traced by the FDA to a California town where spinach fields were bathed in the runoff from nearby cattle ranches.
