Mollusc-free: all about molluscs

Molluscs: the third and final part of the underwater allergens.  In fact, it’s only partly underwater. But what does it mean to be mollusc-free? A bit like with crustaceans, I was a bit hazy as to what molluscs were but luckily Wikipedia informed me that there are 85,000 species out there, of which, I imagine, humans eat only a handful. Given so many species I’d be interested, mollusc allergy sufferers, to know whether you’re allergic to one species or many.

Squids are the biggest and slugs and snails the most numerous. So you’re most at risk in seafood restaurants, or in France. It’s weird, I’ve never heard of anyone eating slugs, but given my research, I don’t see a reason why not.

I don’t think I’ve ever seen a ‘may contain’ for molluscs. I don’t know if that’s because they’re rarer, so cross contamination into places they’re not supposed to be is rarer; or because people aren’t good at labelling. Some sites tell me to beware of stocks. I’ll look out and report back!

As you’ll know if you read my crustaceans part, I really dislike seafood, and apparently molluscs make up the other part of shellfish, so my question mark over shellfish remains. Are you likely to have an allergy to both crustaceans and molluscs? How about fish as well? I couldn’t find any research, so let me know anecdotally instead. A short blog: it seems the internet is a little blank on the subject.

Thanks for reading this part of my series on the top 14 allergens. To find out what I’ve learnt about the other 13 please head to the blog series home.
