Metallic Taste from Shrimp - Zehrs, Guelph Ontario

Guelph, Ontario, Canada

I am from Guelph Ontario Canada, the sauce and shrimp were from zehrs. I had metallic taste after eating certain food, especially during the mid night or the following night after I consumed the food. Then I knew the food wasn't right. The food could be sea food like shrimp or some chocolate not from a well known brand. A couple days ago, after I ate food seasoned with Guinness Bull's Eye barbecue sauce, the taste came to my mouth mid night. The second day, I felt the metallic taste even when I was eating the leftover with Bull's Eye sauce. I had thought it was the shrimp I ate, but I ate only a little, which should not produce that strong taste. I searched online to see whether there's a recall of the sauce, but didn't find any. I'm not very sure it was the sauce or the shrimp, but I'm certain that one of them was polluted.
