Islamic dietary laws inform halal standards, defining which foods are halal (lawful and permissible). Many halal foods are produced in non-Muslim majority countries increasing the likelihood they might be haram (prohibited). Halal certification is one way to operationalize halal standards, hence protecting Muslim consumers. At present there is no unified halal standard guiding halal certification. The aim of this study was to determine the perceived challenges in implementing halal standards in the United States. Semi-structured in-depth interviews were done with a representative from 6 of the 11 halal certifying bodies (HCBs) in the United States. All reported their role was to verify food safety records for compliance with government regulations but not to monitor food safety practices. Two main issues—forged halal certificates and expired halal logos were identified as significant issues. Three HCBs stated there is no problem with having multiple halal standards, but all believed it is necessary to have one universal halal standard with minimum standards followed by everyone. The findings of this study can be beneficial to the U.S. halal industry as it highlights the challenges and issues they face.
