Health Canada removed brominated vegetable oil, or BVO, from its list of permitted food additives on August 30, 2024 and gave industry a one-year transition ending August 30, 2025. The additive had been allowed in limited amounts as a density-adjusting agent in flavourings used in some citrus- or spruce-flavoured beverages.
What BVO did in a beverage
BVO is vegetable oil modified with bromine. In certain flavoured drinks, it was used to help keep citrus oils suspended instead of separating and floating to the surface. Before removal, Canada permitted it in specified beverage flavour preparations at a maximum of 15 parts per million in the beverage as consumed.
It was not present in every soft drink or sports drink. Consumers could check the ingredient list, while manufacturers had to reformulate or relabel affected products during the transition. Similar-looking beverages could use different stabilizers.
Why Health Canada changed the rule
The department completed an updated safety assessment using new and previously reviewed evidence. It concluded that the information no longer supported continuing to permit BVO as a food additive. A public proposal was issued in May 2024, and Health Canada said it received no new safety information during consultation that changed the assessment.
The regulator also stated that it had not found an immediate health concern at the level then permitted. That is why the one-year reformulation period should not be interpreted as advice that a single exposure was an emergency. Removing a permitted use is a risk-management decision based on the weight of evidence and the availability of alternatives.
What research raised concern
Brominated compounds can accumulate in body tissues, and high or prolonged exposures studied in animals have produced effects involving organs such as the thyroid, heart and liver. Evidence from doses used in experiments cannot be translated directly into a prediction for someone who consumed a particular drink, but it can show that continued authorization lacks an adequate safety basis.
Health assessments account for exposure, uncertainty and differences between experimental and ordinary consumption. The relevant question was not whether BVO made every beverage acutely poisonous; it was whether its continued technical use remained justified under modern safety evidence.
What consumers and businesses needed to know
During the transition, the existing conditions of use continued to apply while companies changed formulations and labels. After August 30, 2025, the transition ended. The Canadian Food Inspection Agency is responsible for enforcing federal food requirements, while Health Canada sets additive permissions and safety standards.
A person with a medical concern after consuming a product should seek advice from a health professional or poison-control service rather than attempt a diagnosis from the ingredient list. Businesses need to rely on the current legal list and enforcement guidance, not the old maximum level.
The policy’s meaning is therefore precise: BVO’s permitted additive use was removed in 2024, a one-year compliance period followed, and the previous authorization should not be treated as current after that deadline. Imported products offered in Canada are subject to Canadian requirements as well, so a formulation permitted in another jurisdiction is not automatically compliant. Ingredient information should be checked on the package actually purchased because recipes and labels can change over time.
