- Use separate plates, chopping boards and utensils such as knives and tongs for raw and cooked meats.
- Meat that has been frozen must be thoroughly thawed before cooking.
- Do not wash raw poultry as bacteria from the raw meat can be dispersed causing cross contamination.

- There should be no pink meat visible.
- Use a meat thermometer to check the temperature is above 77 degrees centigrade.
