What are the main food safety concerns that may exist at food stalls

First of all, food is easily contaminated, and the main sources of contamination are: (1) microbial contamination. There may be: unclean raw materials, fine particles such as dust in the air with a large number of bacteria, unclean hands of street vendors contaminating food, unclean utensils, etc.; (2) Chemical pollution.

This includes illegal or excessive food additives, metal contaminants in non-conforming tools, utensils, and chemical contaminants in non-food grade bags or boxes used.

Secondly, due to the imperfection of cleaning, disinfection and preservation facilities, microorganisms multiply rapidly after contamination, and food poisoning and other accidents are prone to occur.

However, objectively speaking, although the problem of food contamination in street stalls is more serious, because this kind of food is generally ready-to-eat, it generally does not deteriorate, unless there is a problem with the raw materials, and food poisoning is not common.

The quality of raw materials can not be guaranteed, the processing environment conditions are poor, and the tableware is unqualified.

Germs, gutter oil, dust, carcinogens, non-edible additives, expired food.

Bacteria, viruses, dust, exhaust pollution, illegal additives, and unclean raw materials, do they count?

a).Food additives do not meet the standard provisions. In order to prevent product deterioration and prolong the deterioration period of products, some unscrupulous operators do not organize production according to the standard requirements, resulting in the excessive use of food additives.

Some enterprises also do not meet the standard due to the preservative content of the preservatives in the raw materials purchased.

ii).The ingredient content does not meet the requirements. A small number of milk powder in the production and processing process mixed with a large number of substitute products, after a very simple processing, seasoning, puffing and other processes to prepare, some even no milk ingredients at all, the protein content is seriously insufficient, less than 3, in essence, has been talked about the letter book is not a macro milk powder, the harm is great, so that there is a "big-headed doll" strange appearance.

What's more, in order to increase the protein content value of milk, a large number of chemical raw materials such as melavan, which can cause death, are added.

c).Sanitation indicators are not qualified. In some foods, the vast majority of the total number of colonies and coliform bacteria are not qualified, which seriously endangers the personal health of consumers.

Poor food production process, non-standard raw material processing, and poor outer packaging may cause coliform bacteria and total number of colonies to exceed the standard.

iv).The labeling of packaged food is not standardized. Some food labels are unclear and uneven, the packaging appearance is relatively rough, the ingredient list on the food label is incomplete, the food is not marked with the food name, factory name, factory address, and there is no production date or shelf life.

V).The problem of excessive heavy metals in aquatic products is more serious. The problem of aquatic products focuses on excessive heavy metals.

This is because aquatic products need to be preserved, transported, preserved, if the control is not strict, will cause the freshness index to be unqualified, in order to ensure the freshness of aquatic products, operators often use heavy metals beyond the standard of nutrient solution. In addition, due to the increasing pollution of seawater in recent years, it is also reflected in seafood, and the excessive heavy metal "cadmium" is the result of environmental pollution.

From the above, it can be seen that China's current food safety problems include not only problems in the production and operation process of enterprises, but also problems in supervision and consumer supervision.

If you are not satisfied, you can still ask.

The food on the roadside stalls has great potential safety hazards, mainly in the following ways:

1. People and cars come and go on the roadside, and the air dust is relatively heavy, which directly pollutes the food.

2. In order to make more money, the hawkers did not control the hygiene of the food, and the expired spoiled food was taken out and sold again after simple processing.

3. Most of the food on the roadside stalls is fried and barbecued, which are well-known "junk food".

Safety indicators of fresh ingredients: vegetable pesticide residues, meat freshness, diseased meat, veterinary drug residues, dry goods, dried vegetables, sulfur dioxide and other bad additives, bleaching preservatives, bad additions of finished food ingredients and seasonings, illegal excessive addition of burning relatives, toxic and harmful substances, etc., and cereal mycotoxin residues.

Safety indicators of edible tableware and leather chain: the total number of colonies on the surface of the tableware, the cleanliness of the surface of the cutting board, mycotoxins, etc.
