Cross Contamination ::

Cross Contamination is nothing but a contamination in a cross way i.e, when a bacteria on a kitchen tool transfers to food via direct contact.

2. Clean and sanitize all work surfaces

3. Remind employees to wash their hands

4. Purchase prepared food

5. Implement a personal hygiene program.
