Endangered shark meat is being sold under misleading labels in the U.S., study finds

Shark meat is available in certain grocery stores, seafood markets, and online in the United States, but a recent study has revealed that the type of shark being sold may not always be accurately labeled. The study, published in the Frontiers in Marine Science journal, found that meat from shark species at risk of extinction is often sold under ambiguous or incorrect labels in the U.S.

Researchers conducted DNA barcoding on 29 shark products, including filets purchased in various states and jerky products bought online. The results were alarming, with 93% of the samples being ambiguously labeled as simply “shark,” and one of the products labeled with a specific species being mislabeled. Endangered and critically endangered species such as the great hammerhead, scalloped hammerhead, tope, and shortfin mako sharks were among the species identified in the samples.

Not only does this mislabeling put the sharks at risk, but it also poses potential health risks to consumers. Some of the species identified, such as the scalloped hammerhead, great hammerhead, and dusky smooth-hound sharks, are known to contain high levels of mercury, methylmercury, and arsenic, which can be harmful to human health.

To address this issue, the study’s authors recommend that U.S. sellers should be required to provide species-specific names for shark meat. Consumers are advised to avoid purchasing products that lack species-level labeling or traceable sourcing to ensure they are aware of what they are consuming and any associated health risks.

In conclusion, the mislabeling of shark meat in the U.S. not only threatens endangered species but also poses health risks to consumers. By implementing stricter labeling regulations and educating consumers on the importance of species-specific labeling, we can work towards protecting both marine life and human health.
