Hand washing after you have been touching raw meat

Explanation:

When handling meat care must be taken not to contribute to the risk of contamination and bacterial proliferation in the food.

To ensure meat quality and food safety for your consumers it is important to be aware of some basic hygiene advice that should become routine in your kitchen.

Before preparing food, hands should be washed, and washed again after interruptions (such as going to the bathroom, handling dirty utensils, stirring hair or touching waste baskets).
