Which foodborne pathogen is commonly associated with deli meats and soft cheeses and poses risk to pregnant women?

• A. Listeria monocytogenes.
• B. Escherichia coli.
• C. Salmonella enterica.
• D. Staphylococcus aureus.

Answer: (A)

Listeria monocytogenes is known for causing listeriosis, a infection that poses special danger to pregnant women and their unborn babies. What makes it stand out is its ability to grow in the refrigerator and contaminate ready-to-eat foods like deli meats and soft cheeses, which people often eat without cooking. In pregnancy, even a small amount can cross the placenta and lead to miscarriage, stillbirth, preterm birth, or severe illness in the newborn.

Other common foodborne pathogens cause illness in the general population, but they aren’t as specifically linked to pregnancy risk through refrigerated ready-to-eat foods. Escherichia coli, Salmonella, and Staphylococcus aureus are typically linked to other foods and scenarios, such as undercooked meats, eggs, poultry, or improper handling, rather than being a particular concern of deli meats and soft cheeses for pregnant individuals.

Prevention is about avoiding high-risk foods and ensuring proper handling: heat deli meats to steaming hot before eating, choose pasteurized soft cheeses, keep refrigerators at proper temperatures, and prevent cross-contamination by washing hands and utensils and separating ready-to-eat foods from raw products.
