The U.S. Food and Drug Administration may have decided that the chemical bisphenol A (BPA) is safe, but the Canadian government has made it clear it thinks otherwise.
Canada has become the first country in the world to take action against BPA in baby bottles.
The chemical – which is also used in plastic packaging – has been linked to a number of health problems in various studies, but some experts do not find the evidence to be strong enough to support a ban.
For example, in the U.S., the FDA has said that BPA is safe for human use. Earlier this year, spokesperson Laura Tarantino said the FDA was not "recommending any change in habits" in regard to the chemical.
After declaring BPA a toxic chemical on Saturday, Canada said it is working on draft regulations to limit its importation and sale.
Some U.S. states have said they are considering similar bans, with surgeon generals from Delaware, Connecticut and New Jersey calling on the government to act to protect children’s health.
