There's yet another warning about radioactive shrimp. Last month it was Walmart. This time it's linked to packages sold at Kroger. AquaStar Corporation is recalling its Kroger Raw E-Z Peel Shrimp, Kroger Mercado Cooked Shrimp, and AquaStar Shrimp Skewers. The FDA says the shrimp, sold in more than 30 states, may be contaminated with a radioactive material that could increase cancer risk with long-term exposure. No illnesses have been reported.
