Consumer Advice
BHA (butylated hydroxyanisole) is a synthetic antioxidant used to prevent oxidation in oils and fat-containing foods such as cooking oils, pastries and crisps. The International Agency for Research on Cancer (IARC) classifies it as 'possibly carcinogenic to humans' (Group 2B); some countries ban or restrict it, while China permits it with limits. Levels in compliant foods are low and overall risk is limited, but reducing intake of fatty, highly processed foods is sensible.
