Lox is not safe to eat during pregnancy because it is typically cold-smoked and not fully cooked, which increases the risk of harmful bacterial contamination, including Listeria. Listeriosis, caused by Listeria, can be dangerous for both the pregnant person and the baby, potentially leading to miscarriage, stillbirth, or serious illness. Therefore, pregnant individuals should avoid eating lox altogether. Safe alternatives include fully cooked salmon or hot-smoked salmon that has been heated to a safe temperature (about 165°F), which eliminates the risk of bacterial contamination while still providing beneficial nutrients like omega-3 fatty acids. If lox is accidentally consumed, it is recommended to stay alert for symptoms such as nausea, vomiting, or fever and consult a healthcare provider if any concerns arise. In summary, avoid lox during pregnancy and opt for fully cooked fish options to ensure safety for both mother and baby.
