Ms. Yang in the southern China port city of Guangzhou bought six high priced giant tiger prawns in October—she was happy with the purchase until she found gel inside the heads of the prawns.
Such gel, the presence of which is not typically detectable upon superficial inspection, is injected some time between when the shrimp are caught and when they’re sold, in order to add weight and thus earn a greater profit. Shrimp sold live have not been injected, because the injection would kill the shrimp.
