Is Costco Food Safe During Pregnancy? Food Court, Rotisserie Chicken, Samples and Sushi

Costco isn't one place to eat, it's five. There's the food court, the rotisserie chicken, the sample tables, the sushi and deli counters, and a cheese aisle bigger than most supermarkets. Each one has its own pregnancy answer.

The short version is that the hot food is easy and the cold, ready-to-eat food needs thought. Here's the store in the order you'd walk it.

The Food Court, Item by Item

Menus vary by warehouse and by country, so use the logic, not just the list. Anything cooked and served hot is generally fine. Anything cold, ready to eat and made ahead is where to slow down.

The soft serve is the one people ask about most. Soft serve machines have been linked to listeria outbreaks in the past, not because the ingredients were unsafe but because the machines weren't cleaned properly. It's a low risk, but it's one you can't check. Our soft serve safety audit goes through it in detail, and a pre-packaged ice cream from the freezer aisle has no such variable.

Rotisserie Chicken: Brilliant, With One Rule

A Costco rotisserie chicken is one of the best things you can buy while pregnant. It's cooked through, cheap, high in protein, and dark meat brings more iron than breast. One chicken covers several meals.

The rule is about time. Cooked chicken should go into the fridge within two hours, or within one hour if it's hotter than about 32°C (90°F) outside. The common mistake is picking it up first, doing the rest of the shop, driving home and leaving it on the counter while you unpack. That can add up to a long time in the danger zone.

So pick it up last, get it home, and either eat it or portion it into the fridge straight away. Leftovers keep for three to four days in the fridge, and you can eat them cold if they were chilled promptly. Our guide on cold chicken in pregnancy explains why properly stored cold cooked chicken is fine. To reheat, heat until steaming throughout, and only once.

One nutrition note. Costco rotisserie chickens are seasoned with a salt solution, so they carry noticeably more sodium than a plain roast chicken. That isn't a safety issue, but if your midwife has mentioned your blood pressure or you're struggling with swelling, pair it with unsalted sides and go easy on the skin.

Strip the meat off the bones on day one, and freeze what you won't eat in three days. It's ready-to-use protein for salads, wraps and pasta for weeks.

The Sample Tables

This is the part of Costco where pregnancy genuinely changes things.

Samples of hot, freshly cooked food, like a meatball or a piece of cooked chicken handed to you steaming, are fine. The concern is cold, ready-to-eat samples: cured meats like salami and prosciutto, soft cheeses, smoked salmon, and creamy dips that have been sitting out.

Listeria grows at fridge temperatures and survives in cold cured and smoked foods. Pregnant women are around ten times more likely to get listeriosis than the general population, and it can be serious for the baby even when the mother feels only mildly unwell. Sample tables add a second factor: food that's been portioned and left at room temperature.

You don't need to avoid the sample tables. Just take the hot ones and pass on the cold cured meat and soft cheese. "Is this cooked?" is a completely normal question, and if the person serving doesn't know, that's your answer.

Going through the deli and chilled ranges for this guide, the thing that stood out was how much of what's offered at sample tables falls into exactly the categories pregnancy guidance flags. That's not a Costco problem, it's what sample tables are for: showing off the premium chilled products.

The Sushi and Deli Counters

Sushi. Raw fish is best avoided in pregnancy because of parasites and bacteria. Cooked options are fine: California rolls made with cooked imitation crab, shrimp tempura rolls, cooked eel, and vegetable rolls. Our sushi pregnancy guide sorts every common roll into safe and skip.

Smoked salmon. Most packaged smoked salmon is cold-smoked, which means it was never cooked. The FDA advises pregnant women to avoid refrigerated smoked seafood unless it's in a cooked dish, and the NHS gives the same advice for cold-smoked fish. Cook it into pasta, scrambled eggs or a bake until steaming. Our smoked salmon guide covers how.

Deli meats. US guidance is to heat deli meats until steaming before eating them in pregnancy. Bulk packs make this trickier, because once opened they only last a few days in the fridge. Freeze portions straight away. Our deli meat guide goes through the options.

Cured meats. Salami, prosciutto and chorizo are safe once cooked, on a pizza or in a pasta sauce. Eaten cold from a charcuterie pack, they're one to skip. Our pepperoni and cured meat guide explains the difference.

Pre-made deli salads. Chicken salad, potato salad and similar are chilled ready-to-eat foods. They're safer than most people fear when they're fresh and kept cold, but check the date, keep them in the fridge, and eat them within a day or two of opening. Our chicken salad guide has the detail.

The Cheese Aisle

Costco's cheese range is huge, and most of it is fine.

Hard cheeses like cheddar, Parmesan, Gruyère and Manchego are low risk in pregnancy. Soft cheeses made from pasteurised milk, like mozzarella, cream cheese, cottage cheese, feta and halloumi, are fine too.

Two things to check. First, look for "raw milk" or "unpasteurised" on imported cheeses, and skip those unless they're going to be cooked until bubbling. Second, UK and US advice differ on soft mould-ripened cheeses like brie and camembert. The US treats pasteurised versions as safe. The NHS advises avoiding them unless cooked, even when pasteurised, because of how they're made. Our pregnancy cheese guide sets out both positions, and if you've already eaten something you're unsure about, our guide to accidentally eating unpasteurised cheese is calm and practical.

A Pregnancy-Friendly Costco Haul

If you're going anyway, Costco is genuinely good for the nutrients that are hardest to hit in pregnancy. Iron, protein, omega-3 and fibre are all cheaper in bulk.

For iron: rotisserie chicken, lean beef mince to portion and freeze, tinned beans and chickpeas, fortified breakfast cereal, and bags of spinach.

For omega-3: frozen salmon fillets, which you cook from frozen or thawed, and tinned salmon. Oily fish is one of the best things you can eat for your baby's brain development, up to two portions a week.

For protein at every meal: eggs, Greek yogurt, cottage cheese, block cheddar, hummus and nut butter.

For fibre and steady energy: oats, wholegrain bread to freeze in slices, frozen berries, frozen mixed vegetables and brown rice.

That trolley covers most of what pregnancy nutrition asks of you, and very little of it needs thinking about from a safety point of view. Our pregnancy grocery list goes through the full version aisle by aisle.

Buying in Bulk While Pregnant

Bulk buying and pregnancy food safety pull in slightly different directions, because big packs sit open for longer.

Freeze in portions on day one. Meat, bread, cooked chicken, berries and cheese all freeze well. You'll waste less and nothing sits open past its safe window.

Eggs. In the US, pregnant women are advised to cook eggs until both the white and yolk are firm. A big tray is fine, just cook them through.

Bagged salad. Bulk bags go off quickly once opened. Keep them cold, use within a couple of days, and bin anything slimy.

Frozen fruit and vegetables are one of the best Costco buys in pregnancy. They're as nutritious as fresh, last for months, and frozen berries in porridge or a smoothie make an easy daily habit.

Costco is a good place to shop while pregnant, and a food court hot dog is one of the safer fast food choices going. The simple rule for the whole store: eat hot food hot, keep cold food cold, and be choosy about anything cured, smoked or raw. If you're looking at other chains, our pregnancy-safe sandwich guide applies the same logic to deli counters generally.
