Prevention

• Do not touch your eyes, nose, or mouth while preparing food or while in the food preparation area.

• Always store cooked foods and raw vegetables at the top of the fridge, and meat at the bottom.

Food Preparation

• We must be careful when preparing foods to slow and stop the growth of pathogens…

• Now we will talk about how to do that.

Wash Fruits and Vegetables

• Did you know that—even if you plan to peel fruits and veggies—it’s important to wash them first because bacteria can spread from the outside to the inside as you cut or peel them?

• Here’s how to wash all your produce effectively…1. Cut away any damaged or bruised areas.2. Rub away dirt gently in a bowl of cool water.3. Rinse under running water.

Wash Fruits and Veggies, Not Meat!!!

• Washing raw meat and poultry can actually help bacteria spread, because their juices may splash onto (and contaminate!) your sink and countertops.

• Meat will be cooked to kill the bacteria, so it does not need to be washed first.
