Hi Chris

I tune into Radio 702 to listen to your show every Friday & just love it!

Several times this summer I have had the unfortunate experience of going to a restaurant and ordering a fish dish with has been off.

Luckily fish has an early warning in that no sooner have you taken one bite it makes your mouth and lips itch like crazy & very strong stilton cheese sometimes does the same.

What causes this itching?

Is it a particular pathogen?

Is this something that only occurs when the weather is warm and protein has been left un refrigerated for too long?

And why don't you get this with chicken or meat?

Looking forward to your response.

Regards,
Nicci

What do you think?

Are you sure that you are not simply allergic to those kinds of foods?

At first I thought it may be an allergic reaction, however I eat tuna and other fish everyday and it doesn't happen. Also my boyfriend experienced the same reaction when he tasted it, on all three occasions. It also seems to be something that happens in particularly hot weather which lead me to believe that the restaurants in question aren't refrigerating foods, rather leaving them out of the fridge between orders, thus creating some kind of bacteria to form.

Is it the same feeling you get when you're eating kiwifruit and fresh pineapples?

It almost sounds like food poisoning, but I have no idea why this would happen in a restaurant![:0]

It is caused by histamine and histamine-like products of bacterial breakdown of seafood, inhibiting its metabolism. The exact aetiology is complicated as histamine is not generally absorbed via the gut and administration of oral histamine does not replicate the symptoms

It is more like that itching sensation you get from very mature cheese. Not the same as the reaction to pineapple. If more foods gave warning signs when they were about to go off it would save a lot of people extreme discomfort!

You didn't get any other symptoms other than itching?

It most certainly was Scombrotoxic food poisoning. The description fits perfectly. Luckily the burning sensation occurred within seconds so i didn't get a chance to swallow more than a mouthful. The itching and flushing were the only other symptoms and they lasted for about an hour afterward.
