After peeling potatoes and before slicing carrots This emphasizes the importance of preventing cross-contamination in food safety, which is vital when preparing meals.
When dealing with food safety in the kitchen, it is important to understand when to clean and sanitize utensils, including knives.
Cleaning refers to removing dirt and food particles, while sanitizing means killing harmful bacteria and viruses. Here are important guidelines about when knives should be cleaned and sanitized:
After peeling potatoes and before slicing carrots: This is essential because different foods can carry different bacteria. Peeling potatoes might transfer some dirt or bacteria to the knife, and it is crucial to clean and sanitize the knife before using it on other vegetables like carrots to prevent cross-contamination.
After 4 hours of constant use: If a knife has been in constant use for an extended time, bacteria can build up on its surface. It is a good practice to clean and sanitize the knife periodically to ensure food safety throughout its use.
After cutting bread and before cutting rolls: Similar to the first point, bread can carry crumbs and moisture that might harbor bacteria. It's important to clean and sanitize the knife before using it on other types of food to avoid any potential contamination.
After being stored in a knife block for a day: Even though a knife may look clean after being stored, it can still accumulate bacteria or dust. It is wise to clean and sanitize it before using it again.
