California, Nevada, Oregon, and Washington health officials are warning that alfalfa sprouts sold by Salad Cosmo USA Corp., a California company, may be contaminated with Salmonella.  Routine testing revealed Salmonella contamination in alfalfa sprout seeds at Salad Cosmo, and the company instituted a voluntary recall of the products.  An article in the San Jose Mercury News identified the recalled products as, "two-and-a-half-ounce plastic containers and one-pound plastic bags of sprouts labeled Salad Cosmo Alfalfa Sprouts with the production codes of 0519 to 0526."

Dozens of foodborne illness outbreaks have been traced to sprouts.  In 2000, Bill Marler called on the FDA to require a warning label on sprouts after a California Salmonella outbreak was traced to contaminated sprouts.
