A recent study of canned tuna packed in oil and sold in Europe revealed toxic chemicals bisphenol A (BPA) and/or glycidol in all of the analyzed tuna products. Mercury and 3-MCPD were not found at levels high enough to cause concern.
The U.S. Food and Drug Administration (FDA) has issued a proposed rule to revise the standard of identity and the standard of fill of container for canned tuna. If finalized, the proposed rule would, among other things, revise the weighing methods used to determine the standard fill of container, allow the use of safe and suitable flavorings and spices as optional ingredients, and clarify that the use of a packing medium is optional.
Consumer Reports (CR) recently tested canned tuna from popular brands, and observed varying levels of mercury, a toxic heavy metal found in foods, on a can-to-can basis.
