Recently, a local food and drug supervision bureau issued a new phase of food safety sampling information, and notified 5 batches of unqualified food. Among them, 3 batches of food were found to have excessive microbial contamination, including nut products and roasted seeds and nuts. The meat products are not qualified for 2 batches. The microbial exceeding the standard of these batches is mainly because the total number of colonies exceeds the standard and the coliform bacteria exceeds the standard. Then, in the face of the total number of colonies, the coliform bacteria exceeds the standard, how can enterprises ensure the safety of food production and processing?
According to industry insiders, in general, there are many reasons for the excessive number of colonies. The sanitary conditions for production and processing are not strictly controlled according to requirements. The cleaning and disinfection of packaging containers is not in place, the packaging of products is not tightly sealed, and the storage and transportation conditions are not properly controlled. The group may exceed the standard, the packaging materials are contaminated, or the processing equipment comes from workers, utensils and other processing equipment, environmental pollution, and sterilization process. The equipment is not in use, and the product sterilization is not complete. .
Microbial contamination exceeded the standard How to ensure food processing safety?
First of all, for the total number of colonies exceeded, it is necessary to disinfect and sterilize the production and processing workshops. It is best to ensure that the food is produced in a sterile, dust-free environment. At present, many food processing enterprises use dynamic air sterilizers, dual-core ozone generators. The workshop is disinfected. Like the packaging workshop, the food output and packaging materials are continuously transported. It is the most susceptible to bacterial contamination. The use of these two types of air purification equipment can effectively solve the microbial contamination problem caused by food production.
Secondly, it is necessary to thoroughly clean the packaging container and processing equipment. Whether it is the packaging container or the processing equipment, it is in the direct contact with the food. The cleaning and disinfection are not complete, and the secondary produced food is highly susceptible to bacterial contamination. Currently, The CIP cleaning equipment that appears on the market is specially used for food contact tools, containers, equipment, etc. for cleaning and disinfection. It is especially suitable for food equipment with strict hygiene requirements, cleaning and sterilization of equipment. CIP cleaning system can achieve thorough cleaning. The effect of disinfection can save energy such as water and steam, and reduce cleaning costs.
Finally, in the packaging process, it is necessary to strictly check the sealing of the package and avoid the problem product from entering the market. We know that the local food sampling test occurs because the total number of colonies caused by the tightness of the seal is excessive, so in the product inspection, the food is sealed. The role of testing instruments is increasingly prominent, saving time and cost for detecting the sealing of food, and improving the reliability of food safety testing.
Compared with the total number of colonies exceeding the standard, the problem of exceeding the standard of coliform bacteria in food production is solved. In addition to the cleaning equipment, the packaging materials are cleaned and sterilized, and the workers in and out of the body are also required to perform dust removal. Sterilization, at this time, the air shower room has a place to use. Install the air shower room in the workshop, it can remove the dust attached to the surface of the human body and carrying items in the processing workshop, thus avoiding the flow of people and logistics.
On the other hand, it is also possible to use new processing equipment, such as new stainless steel antibacterial coating processing equipment. This type of coating processing equipment solves the surface coating wear caused by repeated use, cleaning and disinfection of traditional stainless steel materials, and then brings Escherichia coli. Bacteria such as Staphylococcus aureus, which cause pollution to foods in production. At the same time, this coating can prevent the growth of various bacteria based on the original characteristics of stainless steel materials, but it is in the field of food processing equipment. The application has not yet gained popularity.
In addition, the food sterilization process can not be ignored. Because food production requires multiple processes, in addition to the packaging process, most foods need to be exposed to equipment, utensils and the external environment. In order to avoid the growth of microorganisms in food production, enterprises also need to use Professional sterilization technology and sterilization equipment, it is best to thoroughly sterilize the products under the premise of ensuring nutrients and flavors, so as to ensure the quality and safety of food.
It can be seen that it is not difficult to avoid exceeding the microbial index. Food processing enterprises only need to install air shower facilities. The air sterilization machine ensures that the workshop is clean and hygienic. CIP is used to clean and sterilize processing equipment, avoid secondary pollution of food, and use professional sterilization equipment. Sterilization of food, and finally the use of testing equipment to test the sealing of food packaging, can ensure the safety of production, so as to avoid a series of problems caused by excessive microbial contamination.
