When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
Depending on the cause, you may start having symptoms hours to months after you eat contaminated food. The most common types of food poisoning cause symptoms in 30 minutes to 2 days. Some types of food poisoning by shellfish may take only a few minutes to cause symptoms. You can go back to your normal diet after 2 or 3 days, but for several days avoid fresh fruit (other than bananas), alcohol, and greasy or fatty foods like cheeseburgers, pizza, or bacon. 2  Also avoid highly seasoned or spicy foods and most raw vegetables.
