Kept in copper orbrass vessels,curd(and other acidic food items) reacts with copper and forms toxic compounds which may be unfit for human consumption,and may cause foodpoisoning.thus it is notadvisable to keep curd and other acidic or sour fooditems in copper or brassvessels.

Copper and brass containers are often used for storing and cooking food in many parts of the world. However, some food substances such as milk and sour foods should not be stored or cooked in copper and brass containers. The reason for this is due to the potential health risks associated with these metals.



Copper and brass containers are made up of alloys that contain copper and zinc. When acidic foods come into contact with these metals, they can cause them to leach into the food. This can be dangerous as copper is a toxic metal when consumed in large amounts.



Milk and sour foods are particularly dangerous when stored in copper and brass containers as they are both acidic. The acid in these foods can cause the copper and zinc to leach into the food, which can lead to copper poisoning.



Copper poisoning is a serious condition that can cause a range of symptoms, including nausea, vomiting, diarrhea, stomach cramps, and liver damage. In severe cases, copper poisoning can be fatal.



In conclusion, it is not recommended to store or cook milk and sour foods in copper and brass containers due to the potential health risks associated with these metals. To avoid the risk of copper poisoning, it is best to use containers made of stainless steel, glass, or ceramic for storing and cooking acidic foods.
