Traces of it are widespread, with higher levels found in water or foods grown, raised, or produced in areas with environmental contamination. Exposure to Cs-137 through ingestion or inhalation allows the radioactive material to be distributed in the soft tissues in the body, especially muscle tissue, potentially increasing a person's cancer risk, according to the U.S. Centers for Disease Control and Prevention (CDC). If you purchased any of the recalled shrimp products, do not eat them. Instead, discard or return them to the place of purchase. For questions, contact Aquastar at 1-800-331-3440.
