The food and drug Administration has actually approved galvanized steel storage of food. However, foods that are highly acidic should not be placed in these containers. This is because the acidity from items like tomatoes, citrus fruits, and other similar foods will corrode the zinc coating over time. The disintegration of this coating will allow salts to be absorbed into thebodyafter consuming the products stored.
The absorption of these salts can cause a mild sickness. Ingestion of zinc is not inherently dangerous as the recommended daily allowance for it is around 15 milligrams. Although unsafe for acidic foods, galvanized steel can be used in the construction of pantries and refrigerators.
Food should not be stored in a galvanized container because acids in the food can leach zinc into the food. Hence, the correct option is C.
This is because some of the stuff that makes up the galvanization might leach out in the food. Due to this, our food may become poisonous to some extent. One of the major reasons for the restriction of the use of the galvanized containers for the food is that if the food is acidic ( acidic species are more aggressive to the corrosion of zinc coatings), then it will be converted to zinc salts. This can be poisonous to our bodies.
