According to the International Labour Organization, ingestion of aluminum sulphate can cause a burning sensation in the throat and chest, abdominal pain, nausea, vomiting, and diarrhea. Therefore, despite some misconceptions, aluminium sulphate is not edible and should never be consumed. It is an industrial chemical with significant health risks when ingested, especially in larger quantities.

According to the World Health Organization's Joint FAO/WHO Expert Committee on Food Additives (JECFA), a tolerable weekly intake has been established for aluminum, a component of alum. This raises questions about whether it is safe to use alum in food, a practice historically associated with pickling and baking.
