Scallops Trigger Severe Symptoms - Costco, Juneau Alaska

Juneau, Alaska, United States

Had Costco frozen scallops with dinner. Went to bed and woke up about an hour later with incessant burping and belching and eventually had it coming out both ends - multiple times. It was rough. Everything else we ate we had eaten before, w/ the exception of Bertolli's alfredo sauce (also from Costco wholesale, Commercial Boulevard, I believe, or possibly Fred Meyer, Glacier Highway). | Symptoms: Nausea, Diarrhea, Vomiting, Burping
