Which microbe is linked with deli meats, soft cheeses, produce and can grow at refrigeration temperatures?

• A. Staphylococcus aureus
• B. Vibrio
• C. Salmonella
• D. Listeria monocytogenes

Answer: (D)

Listeria monocytogenes is a psychrotrophic pathogen that can grow in refrigerated conditions, which is why it’s closely linked to foods stored cold. Deli meats, soft cheeses, and even certain produce can become contaminated and still multiply in the fridge, sometimes reaching infectious levels before you even notice a problem. This ability to grow at refrigeration temperatures sets it apart from many other foodborne microbes and explains why these particular foods are singled out as risks. Staphylococcus aureus, Vibrio, and Salmonella don’t share that same strong chill-loving growth habit. Staph can produce toxins if foods sit out at room temperature long enough, but it doesn’t thrive in the fridge. Vibrio is primarily a concern with seafood and warmer conditions. Salmonella is more associated with undercooked animal products and contaminated foods, and while it can survive refrigeration, it doesn’t grow well at typical fridge temperatures.
