Is Feta Cheese Safe During Pregnancy?

Is feta cheese safe during pregnancy?

Feta made from pasteurized milk is safe during pregnancy; feta made from raw (unpasteurized) milk is not recommended. In the U.S., most supermarket feta is pasteurized and labeled, so the practical rule is: read the label, and if it confirms pasteurized, enjoy it. If you can't confirm the source, skip it or cook it until steaming hot.

Why raw-milk feta is the concern: Listeria

The risk isn't feta itself but Listeria monocytogenes, a bacterium that survives in soft, moist, low-acid cheeses and even grows at refrigerator temperatures. Pregnancy lowers cell-mediated immunity, making listeriosis roughly 10 times (by some estimates more) likely than in other healthy adults. While you may feel only mildly ill, Listeria can cross the placenta and cause miscarriage, stillbirth, preterm birth, or severe newborn infection. Pasteurization heats the milk enough to kill it, which is why pasteurized feta clears the bar and raw-milk feta doesn't. Authentic Greek PDO feta and artisanal, farmers-market, or deli-counter feta are more likely to be unpasteurized; brine and salt slow but don't reliably kill Listeria.

Safe ways to eat it and a sensible limit

Pasteurized feta needs no special limit beyond normal sodium awareness; feta is high in salt, so a typical 1 to 1.5 ounce serving (about 1/4 cup crumbled) on a salad fits general guidance. To eat feta of unknown origin safely, cook it until steaming hot throughout (165°F / 74°C), as in baked pasta, spanakopita, or stuffed peppers—this kills Listeria, while briefly melting it on top is not enough. If you already ate raw-milk feta, a single serving is very likely fine, but stay alert for fever or flu-like illness, which can appear anywhere from a few days up to about 70 days (roughly two months) later, and contact your provider if you feel unwell, since listeriosis is treatable with antibiotics.

Breastfeeding and the bottom line

Once you're breastfeeding, the placental transmission route that made feta risky in pregnancy no longer applies, and Listeria is not meaningfully passed through breast milk, so your confidence around pasteurized feta can relax—mothers are generally advised to keep breastfeeding even while treated for listeriosis. Feta's salt and moderate fat don't affect milk supply. That said, raw-milk and unpasteurized dairy still appear on postpartum food-safety caution lists, so the easing applies to pasteurized feta, not a green light for raw-milk feta. Bottom line: pasteurized feta is a green light, while raw-milk feta is a no unless cooked until steaming hot. Read the label, ask at the deli counter, and when in doubt, heat it through or choose a confirmed-pasteurized product. This is general information, not medical advice; your prenatal provider can tailor guidance to your specific pregnancy and risk factors.
