Salmon Causes Lingering Symptoms - Trader Joe's, Portland Oregon

4121 Northeast Halsey Street, Portland, 97232 Oregon, United States

Me and my boyfriend had Wild Caught Salmon two nights ago purchased from there 2 days prior.
After eating it I had diarrhea and a stubborn stomach ache, but it dissipated when I went to bed. The next day (yesterday) my boyfriend had to leave work early due to a migraine, having the urge to vomit, and body chills. It was noticeable he looked ill. We both had brain fog for the rest of the day and evening, but I felt no other gastrointestinal disturbances, him as well. He still has a lingering headache.
I know it was the Salmon as we both had it, but I am unsure if something more nefarious is proliferating in our body. | Symptoms: Diarrhea, Headache, Chills, Gas, Migraine, Vomiting, Stomach Pain
