Zhejiang Food and Drug Administration: The highest rate of unqualified frozen drinks

Among the foods sampled in Zhejiang last year, the qualified rate of sampling for frozen drinks was the lowest; in the cases of foods investigated, the most concentrated use of food additives, illegal production and sales of botulinum toxin needles, and hyaluronic acid needles were similar to those of the most unconscionable types of drugs... Yesterday, The Zhejiang Food and Drug Administration held a news briefing and informed the 2014 food drug supervision and sampling and case investigation.

In 2014, the food supervision and inspection bureau of the Provincial Food and Drug Administration targeted 24 batches, 186 batches, and 11,330 batches, covering food production, distribution and catering services in the province. Judging from the results of supervision and inspection, the overall situation of food quality and safety in our province is good, and the qualified rate of sampling inspection reaches 96.4%.

Supervised random inspection found 405 batches of unqualified samples with a failure rate of 3.6%. Among them, the highest failure rate was for frozen drinks, beverages, baked goods, and alcoholic beverages. In particular, the unqualified rate of frozen drinks reached 11.1%.

Among the sampling samples, there were 140 batches of food with microorganisms exceeding the standard, which accounted for 34.6% of the unqualified batches. The over-standard items were mainly colony index, coliform bacteria, mold, etc. Some of the samples also detected pathogenic bacteria such as Staphylococcus aureus, Vibrio parahaemolyticus, Salmonella, and L. monocytogenes. The emergence of these microorganisms in excess of standards mainly focused on drinking water, meat products, egg products, frozen drinks, cakes, aquatic products, food and beverages, etc. The main reason for the excessive exposure of microorganisms was that some food production and operation enterprises did not strictly control the hygienic conditions during the production and processing, the cleaning and disinfection of packaging containers was not in place, the sealing of product packaging was not strict, and the storage and transportation conditions were not properly controlled.

Vacuum packaging can effectively avoid food contamination during packaging

As mentioned above, "microbiological violations" is the most important reason for sampling unqualified foods. Vacuum packaging is one of the many packages of food. Because it uses the method of squeezing out excess air in the food to seal the food, it is good for preventing food from deteriorating, and is favored by food companies and consumers. Vacuum packaging technology in China was developed in the early 1980s, and vacuum inflatable packaging technology began to be used in small quantities in the early 1990s. With the promotion of small packaging and the development of supermarkets, the scope of application has become more widespread. Some will gradually replace hard packaging and the outlook is very promising.

With the development and application of high-efficiency, multi-functional vacuum packaging machines and packaging materials with excellent barrier properties, and vacuum and packaging, combined with physical and chemical methods such as aeration, radiation, freezing, oxygen absorbents, and ethylene absorbents, vacuum packaging will be developed in the future. Technology will give food a better storage and preservation effect.

Pay attention to the cold chain logistics take the last kilometer of food safety

It is well-known that food safety problems occur in part because foods do not reach the factory standards during the production process. On the other hand, food may cause pollution in transportation and storage. At present, China has about 400 million tons of fresh agricultural produce entering the circulation every year, but more than 20% of its products are not frozen and are wasted during transportation. Cold chain logistics can not only solve the food loss caused by the problem of circulation, but also to ensure that the food transport process is in a low temperature environment, so as to avoid bacterial contamination and other food pollution problems.

In the past two years, in order to further promote the healthy development of China's cold chain transportation and logistics enterprises and improve the service level of cold chain transportation and logistics, the State has proposed to vigorously promote the scale and intensive level of cold chain transportation, strengthen the construction of cold chain logistics infrastructure, and improve the cold chain. Transport logistics standardization system, actively promote the cold chain transportation logistics informationization construction; vigorously develop advanced distribution and distribution modes such as joint distribution; optimize urban distribution vehicles traffic management measures; strengthen and improve industry supervision; increase fiscal and taxation policy support; play industry The role of the association and other opinions.

Food safety needs to start from all aspects

Searching online for "food" keywords is often related to food safety. Although the relevant departments have repeatedly stressed the need to strengthen food safety management and even publish a list of unqualified companies, companies have also vowed to produce products that meet hygiene standards. But why do they have little success? One of the important reasons is that it is impossible to co-ordinate the food from raw materials to consumers. This unsafe element of the whole link, grasping the raw materials, ignoring production, catching production, ignoring the channels... any one link may bring food safety. Hidden danger.

In addition, for food machinery and equipment manufacturing companies, the products produced are in direct contact with the raw materials of food, and their design requirements will pay more attention to material safety and scientific standards, not only to ensure that the machine and food contact without harm, but also to ensure the production of The food meets the relevant standards. This is a big challenge for the vast majority of China's food machinery and equipment manufacturers.
