- Eat hot food hot and cold food cold. It's as easy as it sounds: Eat right when the food comes off the stove. Any food that's been on the counter longer than two hours is not safe to eat.
- Check the labels for expiration dates, and use your nose to test if foods are spoiled. If in doubt, chuck it.
- Thaw in the refrigerator. Don't take out frozen foods to thaw on the counter all afternoon. Instead, put them in the fridge in the morning or defrost in the microwave right before cooking.
- Keep your cooking surfaces clean. Use smooth surfaces to cut meat.
