Health risk assessment of potassium bromate in bread in Ghana.

Introduction: Potassium bromate (KBrO) is an oxidizing agent added to flour to improve bread quality. However, KBrO is nephrotoxic, and a class B carcinogen banned in most countries, including Ghana.

Aim: This study aimed to determine the residual KBrO concentration in bread and to estimate the chemical and carcinogenic risk that is associated with the consumption of these breads in Ghana.
