Frequently asked questions
When can babies eat mackerel?
From around 9 months. Cook it through, flake it finely, and remove all bones. Introduce it deliberately as a fish allergen.
Is mackerel safe with mercury in mind?
Atlantic mackerel is low in mercury and a good choice for babies. King mackerel is a different fish that is high in mercury, so avoid that one.
How do I get all the bones out?
Cook the fish, then flake it apart slowly with your fingers, feeling for the fine pin bones as you go. Take your time, this part matters.
Can I use tinned mackerel?
Choose tins in spring water with no added salt, drain well, and flake carefully for bones. Skip versions packed in brine or heavy sauces for babies.
