Can you eat home-canned vegetables while pregnant?
Check firstOnly after boiling them first, for 10 full minutes. Home-canned low-acid vegetables like green beans, corn, carrots and potatoes can carry Clostridium botulinum toxin, and boiling destroys it.
Why
Low-acid vegetables canned at home are the classic source of foodborne botulism, because the jars may never reach the temperature needed to kill Clostridium botulinum spores, which then produce toxin inside the sealed jar. The CDC advises boiling home-canned foods for 10 minutes before eating to destroy that toxin, and says to throw out any jar that is bulging, leaking, cracked, spurts liquid on opening or smells off. Commercially canned vegetables are processed under controlled pressure and do not need this step.
Safer alternatives
- Commercially canned green beans, corn or carrots, rinsed and heated
- Frozen peas, spinach or mixed vegetables
- Home-canned high-acid pickles and tomatoes made with added vinegar or lemon juice, still boiled if you are unsure of the recipe
- Fresh vegetables roasted or steamed at home

Frequently asked questions
Can botulism from home-canned food hurt the baby?
Botulism toxin makes the pregnant person seriously ill, with blurred vision, trouble swallowing and muscle weakness, and that illness itself puts the pregnancy at risk. The CDC treats botulism as a medical emergency, which is why the 10-minute boil is non-negotiable for home-canned low-acid vegetables.
Do I need to boil home-canned tomatoes or pickles too?
High-acid foods like properly made pickles, relishes and tomatoes with added acid are much less likely to support Clostridium botulinum growth. If you did not make them yourself or do not know the recipe followed tested acid levels, boil them for 10 minutes anyway.
How do I spot a bad jar?
Discard any jar that is leaking, bulging, cracked, has a lid that is loose or swollen, spurts liquid when opened, or has food that looks discolored, moldy or smells wrong. Do not taste it to check, and do not boil it to rescue it, throw the whole jar out.
