We finished eating our meal about one and a half hours ago and my partner has just come to see me because he felt rather hot and noticed a bright red rash on his body (chest, back and neck). He says it doesn't itch and doesn't appear to be swollen. This has never happened to him before. It is quite an even rash, not blotchy just quite red, like sunburn. We had tuna fish steaks (cooked), peppers, mushrooms, sugar snap peas and potatoes cooked in olive oil with an italian garlic and herb seasoning. This has never happened before when we have had tuna fish. Any ideas would be appreciated - thank you, Valerie, U.K
