I'm from the USA, and ran across a reference to Weetabix, so I looked it up. On Amazon, it is listed for sale and for some strange reason, it is certified allergen free of Abalone? Why in the world would breakfast cereal need to be certified to be shellfish free, and for that matter, why free of just Abalone?
