Is prosciutto safe during pregnancy?

What does the evidence say about prosciutto during pregnancy?

1. MotherToBaby's toxoplasmosis fact sheet explains that the parasite Toxoplasma gondii is commonly found in raw or undercooked meat, that people can become infected by eating meat that has not been cooked properly, and that cooking meat until it is no longer pink, confirmed with a food thermometer, is the recommended way to reduce risk. 1
2. A separate MotherToBaby fact sheet on raw, undercooked, and cold meats groups deli meats with fermented and dry-aged sausages under the same instruction: heat these ready-to-eat products to 165°F (74°C), or until steaming hot, before eating during pregnancy, which is the basis for handling prosciutto the same way rather than eating it cold from the package. 2
3. A European multicenter case-control study of pregnant women with newly acquired toxoplasma infection found that inadequately cooked or salt-aged meats was the main identifiable risk factor across study centers, accounting for roughly 30 percent to 63 percent of infections depending on the city, ahead of exposures like soil contact or cat ownership. 3
4. Laboratory testing on salt-aged mutton found that traditional salt-curing and smoking eliminated infective Toxoplasma from every sample tested, which is part of the microbiology behind counting curing as a partial risk-reducer, though the same researchers found that microwave cooking alone left the parasite alive in some samples because of uneven heating, an inconsistency that does not apply to steady stovetop or oven heat. 4
5. A 2022 study in the Journal of Food Protection that tested raw and dry-aged ham from experimentally infected pigs found that standard home-freezer conditions, down to -20°C for up to two weeks, did not reliably inactivate Toxoplasma gondii, directly challenging the common assumption that freezing alone makes prosciutto-style dry-aged ham safe to eat cold. 5

Is prosciutto safe in each trimester?

• First trimester. First-trimester nausea often pushes people toward grazing foods like charcuterie boards, but prosciutto belongs in the same category as any other raw or undercooked meat this trimester: skip it cold, or heat it until steaming, since a new toxoplasmosis infection is a recognized cause of serious congenital illness when it crosses the placenta early in pregnancy.
• Second trimester. The appeal of a quick protein like prosciutto folded into a sandwich or salad does not fade in the second trimester, and the guidance stays the same: crisp it in a pan, tuck it into a hot dish, or bake it into something until it is no longer cool and translucent before eating.
• Third trimester. Continue heating prosciutto through the third trimester rather than relying on the freezer as a shortcut: the most recent research on dry-aged ham specifically found that ordinary home-freezer conditions did not reliably inactivate the parasite, so cooking remains the dependable option as delivery approaches.
