You should cook all poultry items until they reach what minimum internal temperature?

165 degrees Fahreneheit will kill most of the bacteria that can harm humans.

The bacteria lives in warm seawater (like the Gulf of Mexico) and can contaminate seafood, especially raw oysters.

True or False: There are more bacteria on your kitchen cutting board than the toilet seat.

Too many people simply rinse their cutting boards instead of properly washing them, leading to large populations of bacteria that can spread throughout the kitchen.

If it is 90 degrees, you should probably not consume perishable food items that have been left out for more than an hour; the bacteria will quickly flourish.

Cold weather helps rotaviruses to spread; noroviruses, on the other hand, are common year-round.

Knife gouges in plastic boards can be deeper (and collect more germs) than many wooden cutting boards; no matter what type of board you using, thorough cleaning is vital.
