Early Pregnancy: 21 Things to Avoid for Safety (2026)

Why the first trimester matters for food safety

The first trimester of pregnancy is a critical period for fetal development, laying the groundwork for health throughout life. This stage is particularly sensitive, as the growing fetus is vulnerable to influences from maternal nutrition, environmental factors, and food safety practices. The consequences of dietary choices made during these early weeks can impact not only physical development but also cognitive outcomes, making it imperative to be cautious about food intake during this time.

One of the main concerns during early pregnancy involves avoiding foodborne illnesses, which can lead to complications such as miscarriage or severe illness in the pregnant person. For instance, certain foods carry a higher risk of listeria, a type of bacteria that can easily compromise both maternal and fetal health. Pregnant individuals should steer clear of unpasteurized milk, soft cheeses made from unpasteurized milk, and deli meats unless they are heated to steaming hot.

Additionally, seafood is a potential risk factor due to mercury content. Fish such as shark, swordfish, and king mackerel should be avoided altogether. Instead, opt for safer options like salmon or tilapia, which offer beneficial fatty acids without the mercury risk. Raw seafood and undercooked eggs also pose significant risks; hence, it’s best to refrain from sushi and lightly cooked eggs to ensure safety.

Lastly, caffeine and alcohol consumption should be closely monitored. Experts suggest limiting caffeine to 200 mg per day, while alcohol should be strictly avoided as it can lead to a range of developmental issues.
