You’re standing in line. The smell of baking bread hits you, and suddenly, that Turkey Breast sub is the only thing in the world you want. But then the doubt creeps in. You’ve heard the whispers about Listeria. You’ve seen the "no-no" lists on every pregnancy blog since the dawn of the internet. So, can I eat Subway pregnant, or are you relegated to toasted veggie subs for the next nine months? Honestly, it’s a bit of a gray area, but it's not as scary as the forums make it out to be.
The core of the concern isn't actually the bread or the lettuce—though we should talk about the veggies too. It’s the cold cuts.
Listeriosis is a rare but serious infection caused by the bacteria Listeria monocytogenes. For most people, it feels like a mild flu. For a pregnant person, it’s different because the immune system is naturally suppressed to protect the baby. The bacteria can cross the placenta. According to the CDC, pregnant women are about 10 times more likely to get a Listeria infection than the general population. That sounds terrifying. But we need perspective. There are roughly 1,600 cases in the U.S. annually. It's rare. Yet, because the stakes are high, the "rules" exist.
The Great Toasted Debate
If you’re craving a B.M.T. or a Club, the standard medical advice from organizations like the American College of Obstetricians and Gynecologists (ACOG) is pretty clear: heat that meat.
You can't just "warm" it. You need it steaming.
When you ask for your sub to be toasted at Subway, the high-speed convection ovens do a decent job, but are they hitting the internal temperature of 165°F? Maybe. Maybe not. If the worker just slides it in for a standard cycle, it might just be "melty." To be safe, ask them to toast the meat separately on a piece of deli paper until it’s actually steaming hot before they put it on the bread. It might annoy the person behind you in line. Who cares? You’re growing a human.
What About the Veggies?
Most people fixate on the ham and turkey. Surprisingly, the produce can be just as risky, if not more so. Think about the 2018 romaine lettuce outbreaks. Subway has massive supply chains. They have rigorous food safety protocols—like the Gold Standard audits they put their suppliers through—but cross-contamination is a real-world thing.
The bins of lettuce, tomatoes, and sprouts sit out all day. Handlers move quickly. If a stray piece of contaminated ham falls into the shredded lettuce, that's a vector.

If you’re feeling particularly anxious about foodborne illness, skipping the raw veggies and sticking to the cooked items is a valid choice. Or, take the sub home and add your own thoroughly washed spinach and tomatoes. It’s a bit of a hassle, but it eliminates the "bin" factor.
Can I Eat Subway Pregnant? Breaking Down the Menu
Let’s get specific. Not all subs are created equal when you have a "bump" on board.
The Safe Zone: Hot Subs
The Meatball Marinara is generally considered a win. The meatballs are kept in a hot bath, usually well above the temperature required to kill off nasty bacteria. The Steak and Cheese is another solid contender because the steak is usually heated thoroughly on the line or in the toaster.
The Danger Zone: Cold Cuts
Turkey, ham, roast beef, and bologna are the primary culprits. These are "ready-to-eat" meats. The problem is that Listeria can actually grow in cold temperatures—even inside a refrigerator. This is why the USDA is so adamant about heating them to steaming.
The Middle Ground: Tuna and Seafood
Subway’s tuna is mixed with mayo. While some worry about mercury, the skipjack tuna typically used in commercial sandwiches is lower in mercury than albacore. The FDA says 2-3 servings of low-mercury fish a week is actually great for fetal brain development. The real risk here is the mayo sitting out. If the shop looks clean and the tuna is icy cold, you're likely fine, but many doctors suggest skipping deli-mixed salads just to be extra cautious about Salmonella.
Real Talk on Risk Assessment
Let's be real for a second. Millions of pregnant women eat deli sandwiches and have perfectly healthy babies. The risk of Listeria is statistically low. However, "low risk" isn't "no risk."
Dr. Nathan Fox, a high-risk OB-GYN and host of the Healthful Woman podcast, often points out that we take risks every day, like driving a car. Eating a sandwich is a choice of risk management. If eating a cold sub is going to make you lose sleep and check your temperature every hour for three days, just don't do it. The stress is worse for the baby than the sandwich is likely to be.

But if you’re at a work lunch and the only option is Subway? Get it toasted. Get it hot.
Why the Toaster Isn't a Magic Wand
Standard Subway toasting cycles are about 20 to 30 seconds. That is designed to crisp the bread and melt the cheese, not necessarily to pasteurize the meat. If you want to be 100% compliant with safety guidelines, you have two choices:
- Ask them to microwave the meat specifically (if they have one) until it steams.
- Take the sandwich home and pop the meat into a frying pan or a microwave until it's bubbling.
It ruins the "fast" part of fast food, but it guarantees the destruction of pathogens.
Cross-Contamination is the Silent Actor
Even if you order a veggie sub, the knife used to cut your sandwich just cut a turkey sub. The gloves that grabbed your bell peppers just grabbed a handful of ham.
If you have a severe aversion or are in a high-risk pregnancy category, you might want to mention your pregnancy to the staff. Ask them to change their gloves and use a clean knife. Most Subway employees are happy to help if you're polite about it.
What Should I Look For in a Store?
Don't just walk into any location. Use your eyes.
- The "Sneeze Guard": Is it clean? Or is it covered in dried sauce?
- The Meat Line: Are the meats sitting in pools of water? They shouldn't be.
- The Temperature: Does the refrigerated unit look like it's actually cold? You can usually see a thermometer inside the glass. It should be below 40°F.
- The Staff: Are they wearing hairnets? Are they changing gloves between tasks?
A busy Subway is often safer than a dead one. High turnover means the ingredients aren't sitting in those plastic bins for six hours. You want the fresh stuff.

Hard Cheeses vs. Soft Cheeses
Subway typically offers American, Provolone, Monterey Cheddar, and Pepper Jack. These are all pasteurized, hard, or semi-hard cheeses. You don't have to worry about the "soft cheese" (Brie, Camembert, Feta) rule here. The cheese at Subway is safe. The "Cheddar" is fine. The "Swiss" is fine.
Actionable Steps for Your Next Subway Run
If you’re going to do it, do it smart. Here is how you navigate the menu without the panic.
- Priority One: Choose cooked meats. Meatball Marinara, Rotisserie-Style Chicken (heated thoroughly), or the Steak and Cheese are your best bets.
- The "Steaming" Rule: If you must have turkey or ham, do not settle for a light toast. Ensure the meat reaches that 165°F threshold. If it isn't steaming, it isn't "safe" by CDC standards.
- Condiment Caution: Mayo is fine if it’s from a clean, refrigerated squeeze bottle. If it looks like it’s been sitting on a warm counter, skip it. Stick to oil and vinegar or mustard.
- Drink Choice: Opt for bottled water or canned soda. Soda fountains can occasionally harbor mold or bacteria in the nozzles if they aren't cleaned nightly.
- Trust Your Gut: If the shop smells "off" or the lettuce looks wilted and brown, walk out. Your instinct is a powerful tool during pregnancy.
Ultimately, the question of can I eat Subway pregnant comes down to your personal comfort with risk. If you follow the heating guidelines and choose a reputable, clean location, you are mitigating the vast majority of the danger. You don't have to live on crackers and water for forty weeks, but a little extra heat on that footlong goes a long way for peace of mind.
What to Do If You Already Ate It
Maybe you’re reading this after you polished off a cold Italian B.M.T. and now you’re spiraling. Stop. Take a breath.
The incubation period for Listeria can be long—up to 60 or even 90 days—but most people show symptoms within a few weeks. If you don't have a fever, muscle aches, or gastrointestinal upset, you are likely absolutely fine. Mention it to your OB at your next check-up for peace of mind, but don't rush to the ER over a sandwich. Most "scares" end up being just that—scares.
Moving forward, just stick to the "steaming hot" rule. It's the simplest way to enjoy your lunch without the side of anxiety.
Next Steps for a Safe Pregnancy Diet:
- Check the latest food recall lists on FoodSafety.gov once a week.
- Invest in a digital food thermometer for home use to ensure all leftovers hit 165°F.
- Talk to your midwife or doctor about your specific risk factors before making major dietary changes.
