Probably the most prevalent bacteria, salmonella has been turning up all over the place in the past few years. Remember the egg scare of 2010, in which several million eggs were recalled from farms and grocery stores? And just a few weeks ago, 36,000 pounds of ground turkey packed by Cargill were recalled because of salmonella contamination. Then there was 2009, when Keebler cookies, Jenny Craig nutritional bars, and many other products made with peanuts from a Georgia peanut plant contaminated with salmonella were recalled. Spinach had a salmonella scare too, the year after it was found to be contaminated with E. coli. In July, imported papaya from Mexico contaminated with salmonella led to 10 hospitalizations and reports of salmonella poisoning in 23 states . And parents of young children know that salmonella warnings are posted in pet shops to warn of the dangers of touching turtles, lizards, and other reptiles, which can carry the bacteria on their skin and shells.
