Shark DNA Found in Dog and Cat Food
In a shocking discovery, scientists from the National University of Singapore (NUS) have found DNA from endangered and even critically endangered shark species in dog and cat food. The study, published in the journal Frontiers in Marine Science, analyzed 144 samples from 45 pet food products of 16 different brands, all purchased in Singapore. The researchers were able to sequence the DNA and found that about one-third of the products contained genetic material from sharks. The most commonly found species were the blue shark, silky shark, and whitetip reef shark, all of which are listed as “vulnerable” or “endangered” by the International Union for Conservation of Nature (IUCN).
The study also found DNA from other endangered shark species, such as the sicklefin weasel shark, Caribbean sharpnose shark, and sand tiger shark, in a small portion of the pet food samples. The researchers emphasized that the DNA sequencing only reveals which species are present in the food, not the actual amount of shark meat. The study also revealed that none of the pet food manufacturers had labeled the shark content on their packaging, using vague terms such as “white fish” or “marine fish” instead. This misleading labeling makes it difficult for consumers to make informed decisions and could unknowingly contribute to the overfishing of endangered shark species.
The researchers are calling for stricter regulations on the fishing of shark species, including the blue shark, which is not yet officially listed as endangered but is believed to be overfished. They also urge pet food manufacturers to be transparent about the ingredients in their products, especially when it comes to endangered species. This discovery highlights the need for greater awareness and action to protect our oceans and the species that inhabit them.
