A study by Cornell University has found that endangered sea cucumbers, specifically brown sea cucumbers, are being sold in three New York City Chinatown districts. The research, published in the journal Sustainability, identified 10% of the sampled retail market as endangered species. The study's authors suggest the widespread availability of sea cucumbers could contribute to biodiversity loss. Despite some retailers' limited understanding of the sea cucumbers' origin, they were sold at high prices. The researchers are developing tools to trace sea cucumbers' region of origin to aid enforcement and prevention of the sale of endangered species. They also recommend improved labeling, training for retailers, and public outreach to promote the concept of One Health.
