Which foodborne illness is associated with deli meats?

• A. Clostridium perfringens
• B. Listeria monocytogenes
• C. Shigella
• D. Staphylococcus aureus

Answer: (B)

Listeria monocytogenes is the illness most closely linked to deli meats. This bacterium can grow at refrigerator temperatures, so ready-to-eat deli meats that are stored cold but eaten without cooking can transmit infection. It’s especially risky for pregnant people, newborns, older adults, and those with weakened immune systems because it can cause severe illness or fetal complications. Cooking deli meats to a safe temperature kills Listeria, which is why heating them before eating is often advised for at‑risk individuals. Other pathogens are associated with different scenarios—some link to improper reheating, others to poor hygiene or contamination—but the unique concern with deli meats is Listeria monocytogenes.
