Can You Eat Subway While Pregnant? Yes — If You Follow These Rules

Subway cravings during pregnancy are incredibly common — and incredibly stressful when you’re not sure whether your go-to sandwich is actually safe. The short answer is reassuring: yes, you can eat Subway while pregnant. The part that matters is knowing how to order.

The concern isn’t the bread, the cheese, or the sauces. It comes down to one specific ingredient category — cold deli meat — and a bacterial risk that behaves very differently in a pregnant body than it does in anyone else’s. Once you understand that risk and how easily it can be managed, ordering at Subway stops feeling like a minefield and starts feeling like a reasonable lunch option again.

This guide covers exactly what the research says, which Subway items are safe, which to skip, and how to order with confidence at every trimester.

The Short Answer: Yes — With One Key Condition

You can eat Subway while pregnant. The menu has plenty of safe options, and even the items that carry some risk can be made safe with one straightforward step: heat. If a sandwich contains deli meat, it needs to be toasted until the meat is steaming hot — not just warm, but visibly steaming.

Beyond that single condition, most of what Subway offers is perfectly fine during pregnancy. Cooked proteins like meatballs, oven-roasted chicken, and steak are safe without modification. All of Subway’s cheeses are made from pasteurized milk. Their sauces and dressings — including mayo — are commercially prepared with pasteurized ingredients. The veggie options are generally fine with a little common sense applied to raw toppings.

So the “yes” here is a genuine one. It just comes with a toasting rule attached — and that rule is easy to follow once you know it.

Key Insight: The entire Subway pregnancy debate really comes down to one rule: any sandwich containing deli meat must be toasted until the meat is steaming hot — not just warm. Everything else in your order flows from there.

Why It’s a Concern

The concern with Subway during pregnancy isn’t arbitrary caution. It’s rooted in how your immune system changes when you’re expecting, and in one specific bacterium: Listeria monocytogenes.

Pregnancy naturally suppresses certain immune functions to prevent your body from rejecting the baby. That same suppression makes you significantly more vulnerable to foodborne pathogens — particularly Listeria, which can thrive in refrigerated environments and is commonly found in pre-sliced, packaged deli meats. Listeria can grow at cold temperatures in refrigerators, which is precisely why cold cuts served straight from the fridge present a risk that hot, freshly cooked proteins don’t.

What makes Listeria especially serious during pregnancy is that it doesn’t stay in the digestive system. The bacteria can cross the placental barrier, infecting the uterus and directly threatening the baby. Possible outcomes of listeriosis during pregnancy include miscarriage, stillbirth, preterm labor, and neonatal infection — outcomes that are serious enough to justify real dietary caution, even when the absolute risk is low.

Deli meats at any restaurant — including Subway — are sliced in advance, stored cold, and handled across shared surfaces and equipment. That’s the environment where Listeria spreads most easily. It’s not a Subway-specific problem; it’s a cold deli meat problem. And it’s exactly why understanding which foods to avoid during pregnancy matters so much in the first place.

Important Note: Pregnant women are about 20 times more likely to get listeriosis than the general population. When infection does occur during pregnancy, the consequences for the baby can be severe — which is why health authorities are consistent about the guidance, even though the absolute risk remains low.

What the Research Actually Says

The science on Listeria and pregnancy is sobering in terms of relative risk — but the absolute numbers offer important perspective. Listeriosis is rare. One research estimate places the risk at approximately 1 case per 83,000 servings of deli meat consumed by pregnant women. That’s a very small absolute risk, which is why a peer-reviewed analysis published via the National Institutes of Health concluded that avoiding deli meats entirely “does appear to be rather punitive” given that low baseline.

At the same time, the consequences when infection does occur are serious enough that the CDC, the American Pregnancy Association, and most OB-GYNs maintain clear, consistent guidance. The CDC advises pregnant women to avoid deli meat entirely or reheat it to an internal temperature of 165°F — until steaming hot — before eating. That recommendation hasn’t changed, and it applies regardless of whether there’s an active outbreak.

The research also confirms what makes heat so effective: Listeria is easily killed by proper cooking temperatures. The bacterium’s ability to grow in the cold is what makes refrigerated deli meat risky — but that same bacterium cannot survive the temperatures Subway’s toasting ovens reach, which range from 200°F to 500°F. This is why the toasting rule isn’t a workaround or a compromise. It’s a genuinely effective safety measure backed by the underlying microbiology.

The bottom line from the research: the risk is real but manageable, the absolute numbers are low, and heat is the most reliable tool you have for managing it at a place like Subway.

How to Do It Safely

Ordering safely at Subway during pregnancy is less complicated than it might seem. A few deliberate choices — protein selection, toasting confirmation, and topping awareness — cover the vast majority of the risk. Here’s how to work through it from start to finish.

Choose the Right Protein

Your safest Subway protein choices are the ones that aren’t deli meats at all. Meatballs, oven-roasted chicken, steak, and chicken teriyaki are all cooked proteins served hot — no Listeria risk, no toasting required for safety purposes. Board-certified OB-GYN Dr. Kameelah Phillips specifically names Subway’s steak and cheese, oven-roasted chicken, meatball, and tuna sandwiches as options that are “just fine for pregnant women to consume.”

Tuna deserves a brief note of its own. Subway uses skipjack and yellowfin tuna — both lower-mercury varieties — mixed with commercially prepared, pasteurized mayo. There’s no Listeria concern with canned tuna, and the mayo is safe. The only consideration is mercury intake over time: enjoy a tuna sub occasionally rather than daily, and you’re well within safe limits.

If you want a deli meat option — turkey, ham, salami, pepperoni — you can still have it. It just requires the next step.

Toast It Until It’s Steaming — Not Just Warm

This is the single most important step in the entire ordering process. If your sandwich contains deli meat, it must reach an internal temperature of 165°F to eliminate Listeria risk. Subway’s toasting ovens are more than capable of reaching that threshold — but the key word is “steaming,” not “warm” or “toasted.”

When you order, ask the staff directly: “Could you please toast it until the meat is steaming hot?” This is not an unusual request — Subway toasts sandwiches all day, and staff are accustomed to accommodating preferences. When your sandwich comes out, open it and check: the cheese should be melted, and you should see visible steam rising from the meat. If it looks warm but not steaming, ask for it to go back in.

Pro Tip: If you’re in a hurry or unsure about toasting time, pivot to the Meatball Marinara or Sweet Onion Chicken Teriyaki — both are already served hot and require no special modification to be pregnancy-safe.

Navigate the Toppings Confidently

Cheese is not a concern at Subway. All of Subway’s cheese varieties — American, Provolone, Pepper Jack, Shredded Mozzarella, and Swiss — are made with pasteurized milk, which means they’re safe throughout pregnancy. You don’t need to skip the cheese or ask for substitutions.

Sauces and dressings are similarly safe. Subway’s mayo is made from pasteurized eggs, and all of their commercial sauces — ranch, Caesar, buffalo, honey mustard, and others — are prepared with pasteurized ingredients. There’s no need to avoid condiments.

Raw vegetables are where a small degree of caution applies. Fresh produce can occasionally carry bacteria like E. coli or Salmonella, and pregnancy makes foodborne illness harder to fight off. Vegetables that get toasted with your sandwich — onions, bell peppers, jalapeños — are the lowest-risk option. Raw toppings like lettuce and cucumber are generally fine in moderation; just be aware they add a small variable. Raw sprouts are the one topping worth skipping entirely — they carry a higher contamination risk than other raw vegetables and aren’t worth the exposure.

Know the Trimester Picture

The heating rule applies consistently across all three trimesters. Your immune vulnerability is present throughout pregnancy — it doesn’t diminish in the second or third trimester, and there’s no point at which cold deli meat becomes safe without heating. The guidance is the same at 8 weeks as it is at 38 weeks.

Breakfast options at Subway are generally straightforward. Egg-based breakfast sandwiches with bacon or sausage are safe — the eggs are cooked and the meats are heated. Avoid any cold deli meat options at breakfast for the same reasons that apply at lunch or dinner. The logic is consistent regardless of the time of day or the trimester you’re in.

When to Avoid It Completely

There are specific circumstances where the safest move is to skip Subway entirely — or at minimum, avoid any protein-containing options until the situation changes.

• During an active Listeria outbreak linked to deli meats: Even with proper toasting, widespread contamination during an active outbreak raises the risk profile significantly. Check the CDC’s outbreak tracking page periodically, especially if you’re eating deli meat regularly.
• If the meat isn’t visibly steaming when you open the wrapper: Warm is not the same as steaming. If your toasted sandwich doesn’t meet the visual test, don’t eat the deli meat — ask for it to be reheated or swap to a hot cooked protein instead.
• If you’re immunocompromised beyond normal pregnancy changes: Some conditions or medications further suppress immune function. If that applies to you, your provider may recommend avoiding deli environments altogether, regardless of toasting.
• If cross-contamination concerns are high: If you observe staff handling multiple ingredients without changing gloves, it’s reasonable to ask for fresh gloves before your sandwich is assembled — or to choose a different meal. Cross-contamination is a small but real risk that toasting alone doesn’t fully address.
• If nausea or food aversions make Subway unappealing: Especially in the first trimester, if the smell or environment is triggering nausea, trust your body. There’s no nutritional reason to push through it when other options are available.

Common Mistake: Assuming “toasted” automatically means “safe.” Toasting eliminates the bacterial risk in the meat itself — but if gloves aren’t changed between handling different ingredients, bacteria can transfer from other items to your sandwich after toasting. A polite request for fresh gloves is always reasonable.

Frequently Asked Questions

What Happens If I Already Ate a Cold Subway Sandwich While Pregnant?

Most cold deli meat is not contaminated, and the absolute risk of listeriosis per serving is very low. If you’ve already eaten a cold sub, try not to panic. Monitor for symptoms over the next one to four weeks — fever, flu-like aches, muscle pain, or gastrointestinal symptoms — and contact your OB-GYN or midwife if anything develops. A single exposure is unlikely to cause harm, but it’s worth flagging to your provider so they can advise based on your specific situation.

Is Toasting at Subway Really Enough to Make Deli Meat Safe?

Yes — when done properly. Subway’s toasting ovens reach temperatures between 200°F and 500°F, which is well above the 165°F threshold needed to kill Listeria. The key is confirming that your sandwich reaches steaming temperature, not just warmth. Melted cheese and visible steam from the meat are your visual confirmation. If you see both, the heating has been effective.

Can I Eat Subway Tuna While Pregnant?

Yes, with reasonable frequency limits. Subway uses skipjack and yellowfin tuna — both lower-mercury varieties — mixed with pasteurized mayo. There’s no Listeria risk with canned tuna, and the mayo is safe. Enjoy a tuna sub occasionally rather than as a daily habit, and you’re well within the mercury intake guidelines recommended during pregnancy.

Are Subway Sauces and Dressings Safe During Pregnancy?

Yes. All of Subway’s commercial sauces — mayo, ranch, Caesar, buffalo, honey mustard, and others — are made with pasteurized ingredients. There’s no need to avoid condiments or ask for dry sandwiches. The pasteurized mayo in particular is a common concern people raise, and it’s unfounded for Subway’s commercially prepared version.

Is It Safe to Eat Subway Every Day While Pregnant?

From a food safety standpoint, yes — as long as you’re following the toasting rule for any deli meat. From a nutritional standpoint, variety in your diet will better support your prenatal needs than relying on any single restaurant daily. If Subway is your go-to for convenience, focus on protein-rich options, load up on vegetables, and consider rotating with other whole food sources to ensure you’re covering your nutritional bases throughout pregnancy. For more on foods and beverages to avoid during pregnancy, it helps to have a broader reference point beyond just one restaurant.

What’s the Safest Thing to Order at Subway While Pregnant?

The Meatball Marinara and Sweet Onion Chicken Teriyaki are consistently cited as the most straightforward pregnancy-safe choices — both are hot, fully cooked proteins with no deli meat concerns and no special modifications required. If you want more variety, oven-roasted chicken and steak options are equally safe. Load them up with toasted vegetables, pasteurized cheese, and your sauce of choice for a satisfying, worry-free meal.

Eating at Subway while pregnant is absolutely doable — it just takes a little more intentionality than your pre-pregnancy order. Stick to hot cooked proteins when you can, toast any deli meat until it’s visibly steaming, skip the raw sprouts, and load up on your favorite pasteurized cheese and sauces. You don’t have to give up your go-to lunch spot for nine months. You just have to order a little smarter — and now you know exactly how to do that.
