Pregnancy changes your immune system, making you more vulnerable to infections from bacteria sometimes found in unpasteurized juice. These can cause serious complications for you and your baby.
Understanding why unpasteurized juice carries risks helps you make safer drink choices during pregnancy and avoid preventable illness.
Unpasteurized Juice Pregnancy Risk Explained
Unpasteurized juice is not safe during pregnancy. It can contain harmful bacteria that pose serious risks to you and your baby. Unpasteurized means the juice hasn’t gone through pasteurization, a heating process that kills germs like Listeria, Salmonella, and E. coli.

These bacteria can contaminate juice through contact with soil, water, or unclean equipment during production. They survive in unpasteurized juice because it’s not heated enough to kill them. Pregnant people are more vulnerable to these infections because pregnancy changes your immune system, making it harder to fight off dangerous bacteria.
Infections from contaminated juice can lead to pregnancy complications like miscarriage, premature birth, stillbirth, or severe illness for the newborn. For example, Listeria infection during pregnancy can cross the placenta and seriously harm the baby.
Pasteurization involves heating juice to a specific temperature for a short time to destroy pathogens. This makes pasteurized juice much safer for you and your baby. Most store-bought juices are pasteurized and clearly labeled as such.
A typical serving size is about 8 oz (240 ml), which often contains 20 to 30 grams of natural sugars from fruit. These sugars don’t affect the safety regarding bacteria but are worth noting for overall pregnancy nutrition.
While you might see “fresh” or “cold-pressed” juices in stores or farmers’ markets, these are often unpasteurized unless labeled otherwise. If your juice doesn’t say “pasteurized,” it’s safest to avoid it during pregnancy.
Who Should Avoid or Limit Unpasteurized Juice
Pregnant people must avoid unpasteurized juice completely. The risk of harmful bacterial infection is too high during pregnancy, even in small amounts.
People with weakened immune systems, such as those undergoing chemotherapy, living with HIV, or on immunosuppressant medications, should also avoid unpasteurized juice. Their bodies cannot fight off infections as effectively, increasing the risk of severe illness.
Some chronic conditions like certain kidney diseases or diabetes may require caution with juice because of sugar and potassium content. In these cases, your healthcare provider might advise checking labels carefully or limiting juice intake, regardless of pasteurization.
Unpasteurized juice often carries a warning label stating it is not recommended for pregnant people, young children, older adults, or those with weakened immune systems. These warnings highlight the groups most vulnerable to bacterial infections.
Individual advice from your care team always overrides general rules. If you have specific health concerns or questions about juice safety, ask your doctor or dietitian before making changes to your diet.
Safer Alternatives to Unpasteurized Juice in Pregnancy
Choose 100% pasteurized juices such as orange, apple, or fruit blends to avoid the risks of unpasteurized options. Unpasteurized juices include raw apple cider and some freshly squeezed juices sold at farmers’ markets or specialty stores. These can harbor harmful bacteria, while pasteurized versions have been heat-treated to kill pathogens.

Pasteurized orange juice is popular and safe during pregnancy. It offers vitamin C and folate without the bacterial risk found in unpasteurized juice. Always check the label to confirm the juice is pasteurized and that it contains no added sugars or artificial ingredients that may affect your health.
Look for products that state “100% juice” and “pasteurized” on the packaging, with no added sugars or preservatives. Juice blends can provide variety and nutrients but verify each flavor’s label carefully.
If you want to reduce sugar intake or stay well hydrated, water is the safest alternative. Unsweetened herbal teas cleared for pregnancy and diluted pasteurized juice (half juice, half water) offer hydration with fewer calories and sugar.

How Much Juice Is Safe During Pregnancy
No amount of unpasteurized juice is safe during pregnancy. Avoid any juice that has not been pasteurized to eliminate harmful bacteria. “Unpasteurized juice” means juice that hasn’t undergone heat treatment, including raw apple cider and some fresh-pressed fruit juices found at markets.
For pasteurized fruit juices, a typical safe serving is about 4 to 8 oz (half to one cup) per day. This amount provides nutrients like vitamin C without excessive sugar intake.
Keep in mind that juice can be high in natural sugars, which add to your daily sugar load. The American Heart Association recommends limiting added sugars, but natural juice sugars can also contribute to blood sugar spikes and weight gain if consumed in excess.
| Pregnancy Stage or Condition | Safe Juice Amount | Notes |
|---|---|---|
| First Trimester | Up to 4 oz/day | Start with smaller amounts to monitor tolerance |
| Second and Third Trimesters | 4 to 8 oz/day | Supports hydration and vitamin C needs |
| Gestational Diabetes or Excessive Weight Gain | Limit to 4 oz/day or less | Consult your healthcare provider |
| Any Stage | 0 oz unpasteurized juice | Avoid completely to prevent infection |
Checklist Before Drinking Juice or Buying
You can spot unpasteurized juice by checking the label carefully. It often says “unpasteurized” or “raw” plainly, and may carry a warning about safety risks, especially for pregnant people.
Avoid juices bought at farmers markets or from unregulated sources, as they are more likely to be unpasteurized and pose a risk.
Labels with an FDA warning or a clear pasteurization statement mean the juice has been heat-treated to kill harmful bacteria. This process keeps you and your baby safer.
Your healthcare provider’s instructions take priority. If you have a procedure coming up or special medical concerns, follow their advice on juice and fluid intake exactly.
