Question

what is a potential problem with storing raw ground beef above head lettuce?
cross - contact
temperature abuse
clostridium perfringens
cross - contamination

Explanation:

Raw ground beef can have harmful bacteria. If stored above lettuce, juices from the beef can drip onto the lettuce, spreading bacteria and causing cross - contamination. Cross - contact is more about allergen transfer, temperature abuse is about improper temperature storage, and Clostridium perfringens is a specific bacterium but not the overarching problem here.

Answer:

D. cross - contamination
