Can I Eat Subway While Pregnant? (Complete Safety Guide)

The Short Answer

Yes, you can eat at Subway while pregnant. I've spent a significant amount of time reviewing the FDA's guidance on Listeria, and the science is clear: deli meat carries a small but real risk of Listeria monocytogenes contamination, and the fix is simple. Heat it until it's steaming hot. At Subway, that means toasting your sub until the meat reaches an internal temperature of at least 165°F (74°C). If the cheese is melted and the meat feels hot when you bite in, you're good.

But there's more nuance to a Subway order than just hitting the toast button. I wanted to go deeper into exactly which menu items need the heat treatment, which ones are already safe without it, and what the actual bacterial risk looks like in practice.

Why Deli Meat Gets Flagged (and Why You Shouldn't Panic)

When I first started researching this topic, I expected the data to be terrifying. The reality is more measured. Listeria monocytogenes is a bacterium that can survive and even multiply at refrigerator temperatures, which makes it unusual among foodborne pathogens. The CDC estimates that pregnant women are roughly 10 times more likely to contract listeriosis than the general population, because the immune system naturally dials down during pregnancy to protect the fetus.

Here's the part that matters: listeriosis can cross the placental barrier. In severe cases, it can lead to miscarriage, premature delivery, or serious newborn infection. That sounds alarming, and it should be taken seriously. But context matters too. According to CDC surveillance data, there are approximately 1,600 cases of listeriosis per year in the entire United States, and roughly 200 of those occur during pregnancy. The absolute risk is low. The reason we still advise caution is that the consequences, when infection does occur, can be devastating.

The Toasting Rule: What Actually Happens in the Oven

Subway's toasting ovens operate between 200-500°F (93-260°C). Listeria monocytogenes is killed at 165°F (74°C). So the math works out heavily in your favor. When your sandwich comes out with melted cheese and visibly steaming meat, the bacteria simply cannot survive those temperatures.

One thing I want to flag, though: "toasted" and "heated through" are not always the same thing. I've ordered subs at busy locations where the bread was lightly crisped but the meat underneath was barely warm. That's not sufficient. You want the meat itself to be hot to the touch, not just the bread. If it comes out lukewarm, ask them to run it through again. Every Subway location I've tested has been happy to accommodate that request.

Your Complete Menu Breakdown

Safe Without Toasting

These options don't contain cold deli meat, so they're pregnancy-safe as-is:

• Meatball Marinara: This is your safest bet on the menu. The meatballs sit in a hot marinara sauce and are served at temperatures well above the danger zone. It's also one of the highest-protein options available.
• Chicken Teriyaki: The chicken strips are heated before serving. Solid protein, already hot.
• Oven-Roasted Chicken: Prepared fresh and served warm. A clean, lean option.
• Rotisserie-Style Chicken: Pre-cooked and reheated on-site.
• Steak & Cheese: Grilled to order on a flat-top. No deli meat concerns here.
• Tuna: Canned tuna mixed with commercial pasteurized mayo. No Listeria risk. The only consideration is mercury. If you're eating tuna more than twice a week, check our tuna guide for safe limits.
• Veggie Delite: All vegetables, no meat. Completely safe and surprisingly filling if you load it up with avocado and cheese.
• Egg-based options: Cooked through. Safe for pregnancy.

Safe When Toasted (Ask for Steaming Hot)

These all contain pre-sliced deli meat that needs proper heat treatment:

• Turkey Breast: Toast until steaming. This is one of the most popular pregnancy orders, and it works perfectly when heated through.
• Black Forest Ham: Must be heated thoroughly. Request extra toasting time if needed.
• Roast Beef: Make sure the heat penetrates all the way through the layers of meat, not just the surface.
• Italian B.M.T.: Contains salami, pepperoni, and ham. Three types of deli meat means you want this one well-toasted.
• Spicy Italian: Salami and pepperoni. Toast well.
• Cold Cut Combo: Multiple processed meats. I'd recommend asking for double toasting on this one.
• Subway Club: Turkey, ham, and roast beef. All three need heating.

What to Skip

• Any cold deli meat sandwich (untoasted): This is the one hard rule. Don't eat unheated deli meat during pregnancy.
• Salads with cold deli meat: There's no practical way to heat a salad. If you want a salad, build it with chicken, steak, tuna, or go fully vegetarian.
• Pre-made grab-and-go sandwiches: If they contain deli meat and haven't been heated fresh, pass on them.

A Closer Look at Toppings, Sauces, and Cheese

I cross-referenced Subway's ingredient lists against FDA pregnancy safety standards. The good news: almost everything beyond the meat is fine.

Cheese: All Subway cheeses, including American, Provolone, Pepper Jack, Shredded Mozzarella, and Swiss, are made with pasteurized milk. Safe across the board. Melting during toasting provides an additional layer of assurance.

Sauces: Subway's condiments are commercially manufactured with pasteurized ingredients. This includes mayo, light mayo, all mustard varieties, Ranch, Chipotle Southwest, Sweet Onion Teriyaki, oil and vinegar, Sweet Chili, and BBQ sauce. If you're curious about mayo specifically, we have a deep dive in our mayo safety guide.

Vegetables: Lettuce, tomatoes, cucumbers, peppers, onions, spinach, all safe. Subway follows commercial food safety protocols for produce handling, including washing and proper cold storage. Pickles, jalapenos, and banana peppers are preserved in acidic brine, which provides additional bacterial protection.

Avocado and Guacamole: Fresh, nutritious, and safe. If it's available at your location, add it. The healthy fats are excellent for fetal brain development.

How to Actually Order (Without Feeling Awkward)

I know this part can feel uncomfortable. Nobody wants to hold up the line or feel like they're being difficult. But here's the thing: Subway staff toast sandwiches hundreds of times a day. Your request is not unusual.

The Salad Problem (and How to Solve It)

Subway salads are where I see the most confusion. If you're managing gestational diabetes or simply want to skip the bread, a protein bowl or salad is a great option, but you need to think through the protein choice. You can't toast a salad.

• Best choice: Build your salad with Chicken Teriyaki, Oven-Roasted Chicken, Steak, or Meatball Marinara. These are already heated.
• Also great: A Veggie salad with cheese, egg, or tuna for protein.
• Avoid: Any salad with cold turkey, ham, or other unheated deli meat.

Making It Nutritionally Count

Beyond safety, I want to talk about turning your Subway run into a genuinely good meal for pregnancy. Because a sub sandwich can actually be a nutritional home run if you build it right.

Protein: A 6-inch turkey or chicken sub delivers approximately 18-24g of protein. That's a meaningful chunk of the 71g minimum recommended daily during pregnancy by the NHS.

Iron absorption hack: If you go with roast beef or steak (both good sources of heme iron), add tomatoes and peppers to your sub. The vitamin C in those vegetables can increase your iron absorption by up to six times. I talk about this extensively in our iron during pregnancy guide.

Load up on veggies: Ask for extra spinach, then add peppers, tomatoes, cucumbers, and avocado. This isn't just filler. You're getting folate from the spinach, vitamin C from the peppers, and healthy monounsaturated fats from the avocado, which support your baby's neural development.

Bread choice: The 9-Grain Wheat is your best option for fiber and sustained energy. If you're watching carbs, the Protein Bowl skips the bread entirely.

What If You Already Ate a Cold Sub?

I get this question constantly, and I want to lead with this: do not spiral. The statistical likelihood that a single cold sandwich from a major chain caused a Listeria infection is extremely low. Millions of sandwiches are consumed at Subway locations every day without incident.

That said, here is what to do going forward:

• Monitor for symptoms over the next 2-4 weeks: fever, flu-like symptoms, muscle aches, nausea, or diarrhea.
• If you develop a fever above 100.4°F (38°C) with flu-like symptoms, contact your OB-GYN or midwife and mention the deli meat exposure.
• Going forward, apply the toasting rule consistently. It's a simple habit that eliminates the worry entirely.

How Subway Compares to Other Sub Chains

If you're a sub sandwich person (and honestly, who isn't during pregnancy), you might be weighing Subway against other options. I did a full comparison in our Jersey Mike's, Jimmy John's, and Firehouse Subs guide, but here's the quick version:

Common Questions

Is the Subway Meatball Marinara safe during pregnancy?
Yes. It's one of my top recommendations. The meatballs are cooked and held in hot marinara sauce at temperatures that kill bacteria. No toasting needed. It's also high in protein and iron.

Is Subway tuna safe?
Yes. Canned tuna mixed with commercial pasteurized mayo has no Listeria risk. The only thing to be mindful of is mercury. The FDA recommends limiting albacore (white) tuna to 6 ounces per week during pregnancy. Light canned tuna has lower mercury and can be consumed more freely.

Can I eat Subway every day while pregnant?
From a food safety standpoint, yes, as long as you follow the toasting rule for deli meats. Nutritionally, I'd encourage variety. Rotate your proteins and load up on different vegetables to get a broader nutrient profile across the week.

What about Subway cookies?
Baked fresh with pasteurized eggs. Totally safe. And sometimes, honestly, the cookie is the whole reason for the trip. No judgment here.

Are the breakfast sandwiches safe?
Generally yes. Eggs are cooked, and if you choose bacon or sausage, they're heated. Avoid any cold deli meat options at breakfast.

The Bottom Line

Eating at Subway during pregnancy comes down to one simple, evidence-based rule: if it contains deli meat, toast it until it's steaming hot. If you choose an already-hot option like Meatball Marinara, Chicken Teriyaki, or Steak & Cheese, you don't even need to think about it.

I've reviewed the FDA data, the CDC surveillance numbers, and the ACOG recommendations. The risk from properly heated deli meat is essentially zero. You do not need to avoid Subway for nine months. You just need to order smart.
