Shark may contain extremely high levels of mercury contamination that pose a health risk to adults and children.
Shark populations are vulnerable to overfishing, as they mature slowly and do not reproduce quickly. Sharks can be caught and killed by fishermen when targeting other types of fish. The gear used to intentionally catch sharks – pelagic longlines – can be harmful to endangered marine mammals, seabirds and turtles. Sharks are very susceptible to stock depletion and they often possess extremely high mercury levels.
Sharks are one of Food & Water Watch’s Dirty Dozen.
