There are many food problems in supermarkets

with the development of society, supermarkets have become an indispensable part of people's life, and buying food in supermarkets has become a fashion.

for packaged food, consumers will check the production date and retention period marked on the package, but have you ever doubted the internal quality of the product? The investigation of relevant departments shows that there are some problems in some products sold in the domestic market at present: the net content on the packaging bag is inconsistent with the actual weight of the product, the marking of production date and retention period is false, the product composition is false, and so on

But in fact, unpackaged food has more problems. First of all, it can't mark the production date and shelf life at all. Even if it is available at the factory, it can't be reflected at the time of sale. Moreover, the same products with different production dates are mixed together, and even the salesperson doesn't know where the above-mentioned problem of electro-hydraulic servo control doesn't exist.
