shrimp inflated with silicone I was already having some stomach issues but this seemed to make them much worse. When I threw up I found two white, firm but squishy, ice cube sized things. I took them into my doctor and we went over what I had eaten lately. I had jumbo shrimp from Albertson's. They were bagged and frozen but then steamed and flavored in the store. My doctor told me about how shrimp are injected with silicone and silicone like substances and showed me several stories and videos documenting this. We agreed it seemed like this was likely the substance that got partially digested in my system and then showed up when I got sick in the sink.
