Assalam O Alaikum Br. Khan, We have given Halal status on different ingredients used in different Taco Bell products based on their sources. For example the sour cream is not Halal in USA & Canada. I do not know what ingredients they use in UK. I am also updating the Taco Bell's ingredients. We generally recommend Muslims in USA to avoid going to Taco Bell because main ingredients such as cheese, sour cream and main sauces are not Halal.
