Toxoplasmosis: the complete list of prohibited foods during pregnancy

Reminder: what is toxoplasmosis?

Toxoplasmosis is a parasitic infection caused by Toxoplasma gondii, a microscopic parasite found in soil, raw meat, and cat feces. In France, approximately 45% of women of childbearing age are immune. For the remaining 55%, simple dietary precautions can prevent all risk. A serology test is mandatory at the beginning of pregnancy to determine your immune status.

To learn everything about screening, symptoms, and seroconversion, see our complete guide on toxoplasmosis and pregnancy. This article focuses on the dietary question: which foods are prohibited, which require precautions, and which are perfectly safe.

Summary table: prohibited foods, precautions, and allowed foods

The table below classifies more than 30 foods by category and risk level. The colors indicate the status: red = prohibited, orange = precautions needed, green = allowed.

Meat and cooking: temperatures you need to know

Meat is the main source of Toxoplasma gondii contamination in France. The parasite forms cysts in the muscles of animals (beef, pork, lamb, poultry, game). These cysts remain viable until the meat has been cooked to a sufficient temperature.

The Toxoplasma gondii parasite is destroyed at an internal temperature of 67 °C maintained for at least 3 minutes (source: ANSES). Here are the recommended cooking temperatures for each type of meat:

Cured and deli meats: raw vs cooked

The essential distinction for cured meats is simple: raw = prohibited, cooked = allowed. Drying, salting, and smoking do not destroy Toxoplasma gondii cysts. Only cooking at a temperature above 67 °C guarantees elimination of the parasite.

Raw cured meats include dry sausage, cured ham (Parma, Serrano, Bayonne), coppa, bresaola, dried beef, uncooked chorizo, and dried duck breast. All these products are prohibited if you are not immune to toxoplasmosis.

On the other hand, cooked deli meats are allowed: cooked ham, Paris ham, mortadella, cooked Strasbourg sausages, well-cooked pâté en croûte, and sterilized potted rillettes. Canned foie gras (sterilized in jar or can) is also allowed, unlike semi-cooked foie gras whose cooking temperature does not always exceed 67 °C.

Fruits and vegetables: the washing technique

Fruits and vegetables grown in open ground can be contaminated by Toxoplasma gondii oocysts present in the soil. These oocysts are excreted by cats in their feces and can survive several months in moist soil. Rainwater then carries them toward growing areas.

The risk particularly concerns foods in direct contact with soil: lettuce, radishes, carrots, strawberries, cherry tomatoes, zucchini, fresh herbs. Even organic products must be washed: organic farming does not eliminate the risk of parasitic contamination.

Recommended washing protocol

1. Separate the leaves or individual elements (for salads, herbs, strawberries, etc.).
2. Rinse each element under running water for at least 30 seconds while rubbing the surface.
3. Soak for 5 minutes in a vinegar water bath (1 tablespoon of white vinegar per liter of water).
4. Rinse one last time under clean water before consuming.

Fruits whose skin is not consumed (banana, orange, grapefruit, pineapple, watermelon, melon, mango, kiwi) do not require special precautions for toxoplasmosis. However, wash your hands after peeling them, as you can transfer oocysts from the skin to the flesh when cutting.

Fresh herbs and bagged salads

Fresh herbs (parsley, chives, basil, mint, cilantro, dill) present the same risk as leafy vegetables. They are often grown in open ground and can be contaminated by oocysts. Wash them with the same rigor as your salads, separating each sprig and rinsing them under running water.

When in doubt, the simplest solution remains to consume cooked vegetables. A soup, vegetable gratin, sautéed vegetables, or ratatouille pose no toxoplasmosis risk, regardless of the initial washing quality.

Cheeses: the combined toxoplasmosis and listeriosis risk

Cheese is rarely mentioned as a direct vector of toxoplasmosis. The main risk associated with cheeses during pregnancy is listeriosis, caused by the bacterium Listeria monocytogenes. However, a theoretical toxoplasmosis risk exists for cheeses made with raw milk from animals in contact with a contaminated environment.

In practice, the recommendations overlap: soft raw milk cheeses (Normandy Camembert AOP, Brie de Meaux, Reblochon, Mont d'Or) are not recommended for both reasons. Pasteurized cheeses and hard cheeses (comté, parmesan, emmental) are allowed. See our complete guide to cheeses during pregnancy for the detailed list.

Eggs and toxoplasmosis

Eggs are not a vector of Toxoplasma gondii. Regardless of their cooking method (soft-boiled, medium-boiled, hard-boiled, fried, scrambled), they pose no toxoplasmosis risk. Precautions to take with eggs during pregnancy concern only salmonellosis: prefer well-cooked eggs and avoid preparations made with raw egg (homemade chocolate mousse, homemade mayonnaise, tiramisu with raw egg).

Kitchen hygiene rules

Beyond food choices, kitchen hygiene practices play a fundamental role in toxoplasmosis prevention. Here are the rules to follow daily:

Countertops and surfaces

• Clean work surfaces after handling raw meat, soil-covered vegetables, or fresh herbs. Use hot soapy water or a disinfectant product.
• Use separate cutting boards for raw meat and ready-to-eat foods. Cross-contamination can occur if you cut a salad on the same board as raw meat.

Knives and utensils

• Wash knives between each use, especially after cutting raw meat. A knife that just sliced a steak should not be used to cut tomatoes without intermediate washing.
• Do not reuse utensils (fork, tongs) that were in contact with raw meat to serve cooked meat.

Refrigerator

• Separate raw foods from cooked foods in the refrigerator. Store raw meat in a sealed container, at the bottom of the refrigerator, to prevent dripping.
• Clean regularly your refrigerator (every 15 days) to limit cross-contamination.

Hands

• Wash your hands thoroughly (warm water + soap for 20 seconds) after handling raw meat, soil-covered vegetables, soil (gardening), or the cat litter box.

Eating at restaurants while pregnant and not immune

Restaurants are not prohibited during pregnancy, but they require a bit more vigilance when you are not immune to toxoplasmosis. The main problem is that you cannot control the cooking of meats or the washing of raw vegetables.

What you can request

• Well-done meat: specify that you are pregnant and want your meat “well done.” Don't hesitate to send back a dish if the meat is pink in the center.
• Cooked vegetables: soups, sautéed vegetables, gratins, purées. Ask for cooked vegetable sides instead of a green salad.
• Well-cooked fish: avoid semi-cooked salmon (often served pink in the center). Request complete cooking.

What to avoid

• Mixed salads and raw vegetables whose washing you cannot verify.
• Tartares and carpaccios (meat or fish).
• Dishes with undercooked meat: pink duck breast, rare beef fillet, tataki.
• Uncooked fresh herb garnishes.

Our expert's opinion

“The list of prohibited foods for toxoplasmosis may seem long and discouraging at first. In reality, the principle is simple and comes down to two rules: cook meat thoroughly and wash fruits and vegetables well. If you remember these two habits, you eliminate nearly all the risk. I advise my patients to invest in a kitchen thermometer: it's a small purchase that brings great peace of mind. Remember that these restrictions are temporary and that they effectively protect your baby. Monthly serological monitoring is your safety net: even in case of accidental contamination, early management yields excellent results.”
