Is Azodicarbonamide Safe in Bread?

Quick Answer: Azodicarbonamide (ADA) — the "yoga mat chemical" — is banned in the EU, Australia, and Singapore but legal in US bread. When baked, ADA breaks down into semicarbazide, which the EFSA considers a potential carcinogen. The WHO linked ADA to respiratory issues in workers.

Azodicarbonamide is a chemical used both as a flour bleaching/maturing agent in bread and as a foaming agent in yoga mats, shoe soles, and plastic products. It went viral in 2014 when food blogger Vani Hari ("Food Babe") petitioned Subway to remove it — which Subway did. The EU has banned ADA in food since 2005. The primary health concern is that ADA breaks down during baking into semicarbazide and urethane — both of which have shown carcinogenic effects in animal studies. The WHO's Concise International Chemical Assessment found that ADA exposure causes asthma and respiratory sensitization in workers who handle it. Many US bread brands still use ADA, though major chains like Subway, Wendy's, and McDonald's have removed it. It appears on labels as "azodicarbonamide" or "ADA."
