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.
The record-breaking shellfish, 31 years older than the previous oldest animal, another clam, was caught last year when scientists from the Bangor University School of Ocean Sciences were dredging the seabed north of Iceland. The Arctica islandica was among a haul of 3,000 empty shells and 34 live molluscs taken to the laboratory.
