The correct answer is D. The hands can contaminate the toasted bread
Step-by-step explanation:
Bacteria and other pathogens can be easily transferred if you touch different food or use the same elements to touch food. This applies to touch raw meat, which has multiple pathogens and then touching fresh vegetables, bread or any other food that is not going to be cooked because only when you cook raw meat or any other food pathogens can be eliminated. This type of phenomenon is known as cross-contamination. This implies, in the case presented the hands of the chef can contaminate the bread (Option D) due to the transference of contaminants from the raw sausage to the bread.
