Is hummus safe during pregnancy?

What does the evidence say about hummus during pregnancy?

1. Refrigerated hummus, pâté, and meat spreads are best skipped unless they're cooked into a hot dish, and keeping your refrigerator at or below 40°F (4°C) helps slow the spread of Listeria. 1
2. Listeria actually multiplied in hummus over 28 days of refrigerated storage in one lab study, while it declined over time in tahini stored on its own, pointing to the chickpea base, not the tahini, as the bigger driver of risk. 2
3. Listeriosis linked to pregnancy happens about 13 times more often than in the general population, which is why ACOG has specific guidance for people who ate a product later recalled for Listeria contamination. 3
4. Listeria can survive and keep growing even in the refrigerator, and in pregnant women it can cross the placenta and reach a baby whose immune system isn't developed enough to fight it off. 4
5. Pregnancy changes your immune system in ways that make you more prone to foodborne illness in general, which is a good reason to check a refrigerated product like hummus against current recall notices before finishing an open container. 5

Is hummus safe in each trimester?

• First trimester. The Listeria concern with refrigerated hummus doesn't ease up just because it's early in pregnancy. Listeriosis can raise the chance of miscarriage at any stage, so a fresh batch made at home from well-cooked chickpeas, tahini, lemon, and garlic, eaten within a few days, sidesteps the worry tied to the tub-style refrigerated product.
• Second trimester. Guidance holds steady into the second trimester. Refrigeration slows Listeria growth but doesn't stop it, so an opened container of store-bought hummus shouldn't sit in the fridge past its printed date. Warming hummus into a hot dish, like a baked dip or a heated wrap filling, removes the concern entirely.
• Third trimester. Listeriosis linked to pregnancy shows up more often in the third trimester than earlier on, and severe infection at this stage has been linked to preterm labor and stillbirth. The same routine still applies: choose fresh or fully heated hummus, keep your refrigerator at or below 40°F, and check current recall notices for refrigerated dips.
