When you’re expecting, navigating the do’s and don’ts of pregnancy can feel overwhelming, especially when it comes to diet. While nourishing your body with nutrient-rich foods is crucial for both you and your baby, certain foods you previously enjoyed might now be off-limits. Lunch meat, a convenient staple for many, often lands on this list of foods to avoid during pregnancy. But why is this the case?
This article dives deep into why health professionals advise pregnant individuals to steer clear of most deli meats. We’ll explore the risks associated with lunch meat consumption during pregnancy, specifically focusing on Listeria infection. Understanding these risks is the first step in making informed dietary choices to ensure a healthy pregnancy. We’ll also discuss which deli meats might be safer options and what precautions you can take if you crave a deli sandwich.
The Listeria Risk: Understanding the Concern
The primary reason behind the recommendation to avoid lunch meat during pregnancy is the potential risk of Listeria monocytogenes (Listeria) contamination. Listeria is a type of bacteria that can cause a foodborne illness called listeriosis. While Listeria infection is relatively rare, pregnant individuals are significantly more susceptible to it compared to the general population. In fact, pregnant people are about 10 times more likely to get a Listeria infection. For Hispanic pregnant individuals, this risk can be even higher, around 24 times greater.

Listeria bacteria are found widely in the environment, including soil, water, and animal feces. This means that various foods can become contaminated during production, processing, or preparation. Foods particularly prone to Listeria contamination include:
- Raw produce: Fruits and vegetables that grow close to the ground can come into contact with Listeria-contaminated soil.
- Unpasteurized dairy products: Raw milk and cheeses made from unpasteurized milk can harbor Listeria.
- Processed meats and deli meats: These meats can become contaminated after processing, even if they are cooked, and Listeria can grow at refrigeration temperatures. This is a significant concern for lunch meats, hot dogs, pâtés, and certain cheeses.
Lunch meats, due to their processing and refrigeration, provide an environment where Listeria can survive and even multiply. This is why they pose a higher risk compared to freshly cooked meats.
Dangers of Listeria Infection During Pregnancy: Risks to You and Your Baby
For healthy adults, Listeria infection often results in mild, flu-like symptoms, or sometimes no symptoms at all. However, the consequences of Listeria infection during pregnancy can be severe and devastating for both the pregnant person and the developing baby.
While pregnant individuals may experience relatively mild symptoms of listeriosis, such as:
- Fever
- Headache
- Muscle aches
- Fatigue
- Stiff neck
- Confusion
- Loss of balance
- Seizures
The infection can cross the placenta and pose serious risks to the fetus and newborn. These risks include:
- Miscarriage: Listeria infection can lead to pregnancy loss.
- Stillbirth: Infection can result in the death of the baby in the late stages of pregnancy.
- Premature birth: Listeria can trigger early labor and delivery.
- Severe illness in newborns: Babies born with congenital listeriosis can suffer from life-threatening conditions like sepsis (blood infection) and meningitis (infection of the brain and spinal cord membranes).
Due to these significant risks, healthcare providers strongly advise pregnant individuals to avoid foods that are more likely to harbor Listeria, including most lunch meats.
Which Deli Meats to Avoid and Safer Alternatives
To minimize the risk of Listeria infection, it’s generally recommended to avoid the following deli meats during pregnancy:
- All types of sliced deli meats: This includes turkey, ham, roast beef, bologna, salami, and corned beef, whether purchased pre-packaged or sliced at the deli counter.
- Hot dogs and sausages: Unless thoroughly heated.
- Pâtés and meat spreads: These are also high-risk for Listeria.
- Soft cheeses: Unless clearly labeled as pasteurized, avoid soft cheeses like Brie, Camembert, feta, blue cheese, and Mexican-style cheeses such as queso fresco, queso blanco, and panela.
So, what are safe alternatives if you’re craving a sandwich or need a quick protein source?
- Cooked meats from home: Roasting or grilling meats at home and slicing them yourself ensures they are freshly cooked and safe to eat.
- Canned meats and fish: Canned tuna, salmon, and chicken are safe and convenient options.
- Hard cheeses: Hard cheeses like cheddar and Parmesan are generally safe during pregnancy.
- Vegetarian protein sources: Hummus, avocado, beans, and lentils can be used as sandwich fillings or protein-rich snacks.
Making Deli Meat Safer: Heating it Properly
If you have a strong craving for deli meat, or if you are in a situation where it’s your only option, the CDC recommends heating deli meats and hot dogs until they are steaming hot (reaching an internal temperature of 165°F or 74°C) just before eating. Heating effectively kills Listeria bacteria.
You can heat deli meat in several ways:
- Microwave: Place slices of deli meat on a microwave-safe plate with a damp paper towel and microwave until steaming.
- Pan-frying or sautéing: Heat slices in a pan until they are heated through and steaming.
However, keep in mind that even with heating, there’s still a slight risk of cross-contamination if the meat comes into contact with other contaminated surfaces after heating. Therefore, avoiding deli meat altogether is the safest approach during pregnancy.
Additional Food Safety Tips During Pregnancy
Beyond avoiding lunch meat, practicing good food safety habits is crucial throughout your pregnancy to minimize the risk of Listeria and other foodborne illnesses. Key precautions include:
- Wash your hands thoroughly: Wash your hands with soap and water for at least 20 seconds before and after handling food, especially raw meat, poultry, and produce.
- Clean and sanitize surfaces: Use hot, soapy water to wash cutting boards, countertops, and utensils after they come into contact with raw foods.
- Refrigerate promptly: Refrigerate perishable foods within two hours (or within one hour if the temperature is above 90°F).
- Use pasteurized products: Choose pasteurized milk, cheese, and juice.
- Wash raw produce thoroughly: Wash fruits and vegetables under running water, even if you plan to peel them.
- Avoid pre-made salads: Be cautious with pre-made salads like tuna salad, chicken salad, or egg salad from grocery stores, as Listeria can grow in these refrigerated salads. Eat cut melons immediately or refrigerate and consume within 7 days.

While the thought of foodborne illness can be concerning, remember that Listeria infection is still relatively rare. Taking these precautions, particularly avoiding high-risk foods like lunch meat, significantly reduces your risk and helps ensure a healthy pregnancy for you and your baby. If you have any concerns about food safety or think you may have consumed contaminated food, consult your healthcare provider immediately. They can provide personalized advice and address any worries you may have.
