Is Pizza Safe During Pregnancy? (Updated 2026 Guide)
Updated September 9, 2026
The Answer
Yes, properly cooked pizza can be suitable during pregnancy: choose pasteurized cheese, heat meat toppings fully, and follow the exact cooking instructions. Our catalog contains grades from A to F, but these ingredient scores do not establish whether a pizza is safely prepared.
The main pregnancy consideration is food safety: pasteurized cheese, thoroughly heated toppings and centers, and prompt refrigeration of leftovers, followed by reheating to 165°F. Sodium nitrite in cured meat and preservatives such as BHA and BHT raise separate questions about dietary exposure, but limited observational or high dose animal evidence does not establish harm from an occasional serving of pizza.

✓ What's Safe
- • Choose cheese labeled as made with pasteurized milk; ask about the cheese when ordering.
- • Choose pizza with fully cooked meat toppings; heat pepperoni and other cured meats to 165°F or steaming hot.
- • Follow the current package’s exact cooking directions for frozen pizza, pizza rolls, and stuffed pizza snacks.
- • Check that the center and fillings are thoroughly heated rather than judging only by melted cheese.
- • Refrigerate leftovers promptly and reheat them to 165°F before eating.
- • Choose vegetable toppings more often if you want to reduce frequent processed meat intake.
✗ What to Avoid
- • Cold or insufficiently heated pepperoni, deli meat, or dry sausage toppings.
- • Unpasteurized cheese when choosing your pizza ingredients.
- • Stopping cooking as soon as the cheese melts while the center or stuffed filling remains undercooked.
- • Leftovers that were not refrigerated promptly; reheating is not a substitute for safe storage.
- • Treating cauliflower crust, gluten free, or A grade pizza as a guarantee of pregnancy safety.
- • Making cured meat heavy pizza an everyday default; occasional intake is different from frequent processed meat exposure.
Most Common Ingredients in Pizza Products
We analyzed 2,784 pizza products. Here are the most common ingredients, ranked by how often they appear:
Ingredients to Watch Out For in Pizza
These are the most common flagged ingredients across 2,784 pizza products we analyzed.
sodium nitrite
Caution
Sodium nitrite is a chemical compound commonly used as a preservative and color fixative in processed meats.
Is regulated at low food additive levels, but frequent cured or processed meat intake has limited observational pregnancy concerns; cyanide antidote and contaminated water exposures are separate issues.
Flagged in 661 of 2,784 products (24%)
bha
Caution
BHA (beta hydroxy acid) is a chemical exfoliant commonly used in skincare to penetrate pores, remove dead skin cells, and improve skin texture.
Has limited pregnancy specific human data and normal regulated food use appears lower concern than high dose animal exposures that drove carcinogenicity classifications.
Flagged in 616 of 2,784 products (22%)
bht
Caution
BHT (butylated hydroxytoluene) is a synthetic antioxidant commonly used as a preservative to prevent the oxidation of fats and oils in food products.
Has limited human pregnancy data, with low concern at reviewed cosmetic levels but reproductive and thyroid related findings in high dose oral animal studies.
Flagged in 598 of 2,784 products (21%)
sodium aluminum phosphate
Caution
Sodium aluminum phosphate is a leavening agent commonly used in baked goods to produce carbon dioxide and help the dough or batter rise.
Has developmental concern at higher chronic exposures, but regulated vaccine adjuvants and occasional clinician directed antacid use should be considered separately.
Flagged in 338 of 2,784 products (12%)
sodium aluminum sulfate
Caution
Sodium aluminum sulfate is a leavening agent commonly used in baking to help dough and batter rise.
Has developmental concern at higher chronic exposures, but regulated vaccine adjuvants and occasional clinician directed antacid use should be considered separately.
Flagged in 65 of 2,784 products (2%)
hydrogenated soybean oil
Caution
Hydrogenated soybean oil is a processed vegetable oil that has been chemically altered to become solid at room temperature, often used in processed foods to improve texture and shelf life.
Mainly raise concern when partially hydrogenated and high in artificial trans fat; fully hydrogenated oils are mostly a saturated fat limit rather than the same trans fat issue.
Flagged in 47 of 2,784 products (2%)
sage
Caution
Sage is a fragrant, gray green herb known for its earthy, slightly peppery flavor and aromatic leaves, often used to enhance savory dishes and herbal remedies.
Is generally low concern at normal culinary amounts but medicinal teas, extracts, supplements, and essential oil should be avoided or clinician reviewed in pregnancy due to limited data and thujone exposure concerns.
Flagged in 46 of 2,784 products (2%)
fennel
Caution
Fennel is a crunchy, aromatic vegetable with a bulbous base, feathery fronds, and a mild, sweet anise flavor often used in salads, soups, and Mediterranean dishes.
Is generally low concern at normal culinary amounts but should be avoided as concentrated medicinal tea, essential oil, or supplement during pregnancy because safety data are limited and estrogenic or uterine concerns exist.

Your Questions Answered
Is it safe to eat pizza while pregnant?
Yes, properly cooked pizza can be suitable during pregnancy. Choose pasteurized cheese and make sure meat toppings and the center are fully cooked. Safe storage matters too: refrigerate leftovers promptly and reheat to 165°F.
Can you eat pepperoni pizza when pregnant?
You can eat pepperoni pizza when the pepperoni is heated to 165°F or steaming hot, rather than added cold after baking. This addresses the separate food safety concern associated with cured meats. Sodium nitrite is a regulated curing additive, and limited observational pregnancy evidence about higher processed meat exposure does not establish harm from an occasional serving. Choosing vegetable toppings more often can help reduce frequent processed meat intake.
Can you eat mozzarella on pizza when pregnant?
Choose mozzarella made with pasteurized milk. Check the package or ask the restaurant rather than assuming every mozzarella is pasteurized. Cook the pizza thoroughly: melted mozzarella alone does not establish that the center or meat toppings are cooked.
Are frozen pizza and pizza rolls safe during pregnancy?
They can be suitable when cooked according to the exact current package instructions. Pizza rolls and other stuffed snacks need thoroughly heated fillings, not just a hot exterior. Do not substitute directions from a different pizza or rely only on browning and melted cheese. An ingredient grade does not measure cooking or pathogen risk.
Can I eat leftover pizza while pregnant?
Refrigerate leftover pizza promptly and reheat it to 165°F before eating. Make sure the center and toppings reach that temperature, not just the edges. If the pizza was not refrigerated promptly, do not rely on reheating to make it suitable.
Is cauliflower crust or A grade pizza safer during pregnancy?
Neither cauliflower crust nor a gluten free label makes pizza intrinsically safer during pregnancy or nutritionally equivalent to another pizza. Our catalog contains 2,784 products, including 1,023 with an A ingredient score; that is not a count of independently verified safe products. Grades do not measure pathogens, dose, preparation, or current package contents, and a low grade is not automatically a clinical warning. Check the actual label and cooking directions regardless of the crust or score.
Do preservatives or herbs make pizza unsafe during pregnancy?
An ingredient name alone does not establish that a serving is harmful. In food, BHA means butylated hydroxyanisole, not a skincare exfoliant; pregnancy data for BHA and BHT are limited, and high dose animal findings do not establish harm at ordinary dietary amounts. Sage and fennel used as normal seasonings are lower concern than concentrated teas, extracts, supplements, or essential oils. You can compare labels to reduce optional additives without treating every flagged pizza as unsafe.
How to Interpret These Ratings
Our ingredient and category rules generate letter grades from the information recorded in the catalog. Missing ingredients and broad category assignments can affect the result. These grades do not measure your dose, confirm a complete current label, or test a product for contamination.
A high grade is not a guarantee of pregnancy safety. A low grade is not, by itself, proof of harm from every use. Follow the product-specific guidance above, check the actual package, and ask your prenatal clinician about supplements, treatment decisions or uncertain exposures.
