Frozen Shrimp Quality Issue: Red/Black Discoloration and Strange Odor

Our observation of the frozen shrimp revealed potential quality concerns. The freezing method employed is water freezing, which results in the entire box of goods being frozen into a single block. While all shrimp are frozen solid, exhibiting a hard texture, some shrimp heads and/or bodies display alarming discoloration, appearing red or black. Furthermore, a strange odor emanates from certain boxes of goods.
