Question

what is the second - leading cause of food - borne illness?
cross - contamination of ready - to - eat foods
failure to clean uniform
not wearing gloves

Explanation:

Food - borne illness can be caused by various factors. Cross - contamination of ready - to - eat foods is a significant cause. When raw foods (such as raw meat, poultry, or seafood) come into contact with ready - to - eat foods (like salads, fruits, or bread), harmful bacteria can transfer. This is a common and major issue in food safety.
Failure to clean uniforms can also be a problem as dirty uniforms can harbor bacteria, but it is not typically the second - leading cause.
Not wearing gloves, while a hygiene concern, is also not the second - leading cause compared to cross - contamination.

Answer:

Cross - contamination of ready - to - eat foods
