Can I eat deli meat during pregnancy?

The listeria risk is real

Pregnant people are about 10 times more likely to contract listeriosis than the general population, and the maternal-fetal consequences can be severe: stillbirth, preterm birth, neonatal sepsis, miscarriage1. The CDC explicitly warns pregnant patients about ready-to-eat deli meats as one of the highest-risk listeria sources.

Listeria monocytogenes can grow at refrigerator temperatures, unlike most foodborne bacteria. So even properly refrigerated deli meat can develop contamination over time.

The heat-to-steaming rule

The CDC and ACOG recommend heating deli meats and luncheon meats to steaming hot (internal temperature 165°F / 74°C) before eating during pregnancy. This kills any listeria present2. Practical applications:

• Microwave deli meat for 15–30 seconds until visibly steaming
• Choose hot sandwiches (Italian sub heated; panini; melt) over cold sandwiches
• Fresh-sliced deli meat eaten the same day is lower-risk than packaged but still benefits from heating

What about hot dogs?

Hot dogs are also on the listeria-risk list and should be cooked to 165°F. Most hot dogs come pre-cooked but can be re-contaminated after packaging.

Sodium nitrate / nitrite — the secondary concern

Cured deli meats (salami, prosciutto, pepperoni, bologna) contain sodium nitrate or sodium nitrite as preservatives. These compounds:

• Form nitrosamines during cooking, which are animal carcinogens
• Have been associated with elevated cancer risk in long-term high-consumption studies (non-pregnancy)
• Have not been specifically linked to pregnancy harm at typical consumption levels

The pregnancy advice on cured meats focuses on listeria (the acute risk) more than nitrates (the chronic risk)3. Moderate cured-meat intake during pregnancy is generally considered acceptable as long as the listeria concern is addressed via heating.

Other high-risk listeria foods

• Pre-made deli salads (chicken salad, tuna salad, ham salad)
• Soft cheeses unless made from pasteurized milk (feta, brie, queso fresco, Camembert, blue cheese)
• Refrigerated smoked seafood (avoid unless cooked into a dish)
• Unpasteurized milk and juice
• Raw sprouts (alfalfa, mung bean, clover)

Safer protein swaps

For sandwich protein: heated fresh-roasted turkey or chicken breast, hard-boiled egg, hummus, properly-cooked fish (avoid mercury list), tuna salad made at home from canned tuna.
