Final answer:
Proper handwashing is essential in food safety and avoiding foodborne diseases, and the only activity listed that does not require immediate handwashing is reading a recipe. Frequent handwashing is needed after answering the phone, opening the refrigerator, and after eating, drinking, or smoking.
Step-by-step explanation:
When considering when to wash hands during food preparation, handwashing should occur frequently to avoid the spread of pathogens. Based on the CDC recommendations, you need to wash your hands in many scenarios except for reading a recipe. Frequent handwashing is required after activities such as answering the phone, opening the refrigerator, and especially after eating, drinking, or smoking because these activities can contaminate your hands.
Proper handwashing is one of the most crucial steps for maintaining food safety and avoiding foodborne diseases. It's vital to wash hands thoroughly with soap and water for at least 20 seconds, following the recommended steps, which includes scrubbing the back of your hands, between your fingers, and under your nails.
Although the scenarios provided may seem less obvious when it comes to handwashing, it's clear that one does not need to wash hands immediately after reading a recipe, as this activity is unlikely to contaminate the hands with pathogens. However, handwashing is essential after touching items that are frequently handled by others, such as phones or refrigerator handles, or engaging in personal activities that could lead to contamination.
