As the deadliest recalled food on this roundup, outbreaks connected to romaine lettuce and bagged salads were likely caused by contaminated water used to irrigate fields in California and Arizona, where most of the lettuce in the U.S. is grown.

1. Leafy Greens

Listeria poses a huge threat according to Consumer Reports, since 90% of people infected with it end up hospitalized, and sandwich-making ingredients pose one of the biggest risks here.

2. Deli Meats and Cheeses

Since E. coli often pops up where animal droppings are, it's no surprise that the bacteria exists in pastures and on feedlots. E. coli can make its way inside the animal itself, too, contaminating beef products.

3. Ground Beef

Contaminated irrigation water is the most likely culprit behind some substantial salmonella-related onion illnesses. Avoid onions that are bruised or damaged and cooking them is always a safe bet to kill off bacteria.

4. Onions

The defeathering process can spread salmonella bacteria in poultry preparation. As with any raw meat, wash your hands directly after handling and make sure you cook the meat thoroughly.

5. Turkey

Chicken is subject to the same defeathering debacle as turkey, plus chickens are often raised in crowded, filthy environments that are essentially bacteria breeding grounds.

6. Chicken

Papayas imported from Mexico pose the biggest threat for salmonella contamination since the FDA encounters more difficulty inspecting products from outside the U.S.

7. Papayas

Peach orchards located near animal feedlots can lead to salmonella contamination. Cooking the fruits helps kill off bacteria, but if you're enjoying a fresh peach, just make sure you choose one that's bruise-free and wash it before you eat it.

8. Peaches

Melon madness via salmonella contamination most commonly ensues when the fruits are cut into cubes or balls and packaged before distributing.
