Heated Deli Meats (Steaming)

Safety Status: Safe to Consume

Deli meats—such as turkey, ham, roast beef, bologna, and chicken slices—are safe to consume during pregnancy only if they are heated until steaming hot immediately before eating.

The U.S. Department of Agriculture (USDA), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) advise pregnant individuals to avoid cold cuts and deli meats unless they have been cooked to a safe internal temperature of 165°F (74°C). This thermal treatment is necessary to destroy any potential pathogens, particularly the bacteria Listeria monocytogenes.

The Threat of Listeria in Cold Meats

Cold cuts are highly susceptible to contamination by Listeria monocytogenes. Listeria is a resilient bacterium that is uniquely capable of surviving and multiplying in cold, moist environments, including commercial refrigerators.

• Cross-Contamination: Even if deli meats leave the manufacturing facility free of bacteria, they can easily become contaminated at the deli counter. Slicing machines, knives, countertops, and hands can transfer Listeria from one product to another.
• Listeriosis Risks: Pregnant individuals are about 10 times more likely to get listeriosis than the general population due to normal alterations in immune function. While the mother may only experience mild, flu-like symptoms (fever, muscle aches, fatigue), the bacteria can cross the placenta. This can lead to miscarriage, premature birth, stillbirth, or severe neonatal infections such as meningitis or sepsis.
• Resistance to Cold: Standard refrigeration does not kill Listeria; it only slows its growth. Heat is the only reliable way to destroy the bacteria.

Safe Reheating & Handling Guidelines

To enjoy deli meats safely, you must follow these preparation protocols:

• Heat to Steaming Hot: Use a microwave, stove, or oven to heat the meat. The meat must reach 165°F (74°C) and emit visible steam. Lukewarm meat is not safe, as a warm environment can actually accelerate bacterial growth.
• Eat Immediately: Consume the heated meat immediately. Do not allow it to sit and cool down to room temperature, as bacteria can re-contaminate the food.
• Prevent Cross-Contamination: Clean all cutting boards, plates, and utensils that have touched cold deli meats with hot, soapy water before using them for other foods.
• Avoid Excess Sodium and Nitrates: Even when heated, deli meats are high in sodium and chemical preservatives like nitrates. Consuming high levels of sodium can contribute to gestational hypertension and fluid retention, so keep portion sizes moderate.
