What must be done if a person changes tasks while using a knife?

When a person changes tasks while using a knife, it is essential to sanitize the knife immediately. This is crucial for maintaining food safety and preventing cross-contamination. Different tasks may involve different ingredients, some of which can pose health risks if mixed. For example, using a knife that has been in contact with raw meat and then using it on vegetables without proper cleaning could lead to the transfer of harmful bacteria.

Sanitizing the knife right away ensures that any pathogens present are eliminated before the knife is used for another food item, helping prevent foodborne illnesses. This practice aligns with standard food safety protocols, which emphasize the importance of cleanliness and sanitation in the kitchen environment to protect both the customers and the staff.
