In order to make sure Halal slaughtered meat is used across all branches of a company or business, it needs to be Halal certified. For example, if a catering company is supplying food to schools or other organizations, it needs to make sure that the supplier of its meat has been authorized by the local council as Halal. It would also need to ensure that all its own staff is appropriately trained in the correct methods of slaughter and any other aspects covered by Islamic law. https://iasiso-europe.com/uk/b....log/what-is-halal-ce
