What is the ruling on using sweets, sugars, and preservatives and colorings that carry the symbol E, which are said to be derived from animal or human origins?

Food additives, used for preservation or coloring, are of two types: natural and artificial. Some of them may contain animal parts. It is forbidden to consume foods that contain substances derived from humans, or from an animal that has not been ritually slaughtered (dhabihah), or from an animal that ritual slaughter does not make permissible, such as pork. Likewise, it is forbidden to consume foods proven to be harmful, due to the Almighty’s saying: ﴿And do not kill yourselves﴾ [An-Nisa’: 29], and due to the Prophet’s (peace be upon him) saying: “There should be neither harming nor reciprocating harm.” Manufacturers must avoid using forbidden or harmful substances, and consumers must exercise caution and avoid these foods as much as possible.
