Health Canada has issued a warning that shark and tuna diets may be unsafe.
It said it is concerned about the potential effects of fish-eating on the health of humans and animals and that the products contained in these diets are “unsafe and potentially harmful to humans.”
Health Canada says the product can cause “dental disease” if swallowed or breathed into the lungs.
It recommends avoiding consuming shark or tuna meals containing them, and if you have a toothache, rinse it out with plain water and avoid drinking the water.
Health Canada’s Food Safety and Food Labeling Branch says in its latest warning, the product contains fish oils and fish protein.
The products are not safe for consumption, the Food Safety Branch says.
It says the products are “highly toxic to marine animals” and “can cause dental disease if ingested or breathed.”
