  Often 𝐬𝐞𝐚𝐟𝐨𝐨𝐝 is what is named to anything coming from the sea. But this name seems to be mixed or interchanged with 𝐬𝐡𝐞𝐥𝐥𝐟𝐢𝐬𝐡. Let’s clarify this. 𝐒𝐡𝐞𝐥𝐥𝐟𝐢𝐬𝐡 is made of 𝘴𝘦𝘢 𝘮𝘰𝘭𝘭𝘶𝘴𝘤𝘴 and 𝘤𝘳𝘶𝘴𝘵𝘢𝘤𝘦𝘢𝘯𝘴 Both groups are very different.

Important notes:
As with fish, if you have reacted, but the tests are negative, think of 𝐀𝐧𝐢𝐬𝐚𝐤𝐢𝐬 allergy. Remember, if you have reacted to 𝐜𝐫𝐮𝐬𝐭𝐚𝐜𝐞𝐚𝐧𝐬, you need to be tested for 𝐡𝐨𝐮𝐬𝐞 𝐝𝐮𝐬𝐭 𝐦𝐢𝐭𝐞𝐬! www.facebook.com/permalink.php?story_fbid=319900496803835&id=100063516604410

If there were no specific allergens on the table I made, it is because none has been identified yet, though some proteins have been. Some main aspects to note are the following:
There are cases in which an apparent allergic reaction to fish has normal investigations.
Final note: Think of the fish in a 𝘧𝘪𝘴𝘩 𝘵𝘢𝘯𝘬! www.facebook.com/permalink.php?story_fbid=319899903470561&id=100063516604410  |
