Chicken
Having the same characteristics as eggs, chicken has a tendency to come standard with salmonella, and, time plus low temps is a recipe for disaster as those bacteria multiply. The best and safest way to avoid this is to make sure that the internal temperature of your chicken reaches 165 degrees.
Microwaves don’t always heat evenly or to as high a degree as other cooking methods, so turning the meat and making sure the entire thing is hot helps. Also, don’t reheat it more than once—if you have chicken leftovers, use them in your salad.
Speaking of chicken… This is really the ultimate gift for those who love to cook/eat chicken!
