On December 21, according to media reports, law enforcement officers of Shanghai Baoshan District Market Supervision Bureau found a hose with a medical needle in a corner of a bullfrog shop during a routine inspection of a market under their jurisdiction. For the above-mentioned illegal acts of adulteration, Baoshan District Market Supervision Bureau imposed a fine of 50000 yuan and confiscated the illegal tools. The practice of injecting water into fresh animal raw material food is legally characterized as an illegal act of adulteration, which violates laws and regulations such as the food safety law, the law on the quality and safety of agricultural products and the measures for the supervision and administration of the quality and safety of edible agricultural products in the market. It is fined 50000 yuan and the illegal tools are confiscated, which is in line with the principle of equal punishment, The higher amount of fines also reflects the spirit of the rule of law of strict regulation. Food is the foundation of the people, and safety is the first. In the field of food safety, water injection adulteration is a typical illegal act. The purpose of illegal elements to inject water into meat is either to increase the weight of meat to increase sales profits, or to keep the surface of pork moist in the short term to sell better. On the surface, this is a quantitative fraud. The actual harm is that water injection will destroy the organizational structure of meat, not only affect the taste, but also have the risk of corruption and deterioration, which is very easy to induce safety accidents. According to the relevant provisions of the criminal law, those involved in a large amount of money and serious harm will also be investigated for criminal responsibility. In fact, there are also great differences in criminal convictions for the judicial determination of water injected meat, according to the type of water injected into water injected meat and the nature of meat after water injection, including the crime of producing and selling fake and shoddy products, the crime of producing and selling food that does not meet safety standards, etc. The results of punishment are different for different crimes. Query the China judicial documents network found that a criminal case tried by the Yingquan District Court of Fuyang City, Anhui Province in 2016 showed that the defendants Qin mouxi and Qin moulong treated pigs for water injection and salbutamol injection in the workshop of raising and selling pigs. As a result, Qin mouxi was sentenced to 10 years' imprisonment and fined 1.5 million. Qin moulong was sentenced to two years' imprisonment and a fine of 100000. With a lesson from the past, why there are still illegal and criminal acts of injecting water into bullfrogs, this case is worthy of detailed analysis. On the one hand, the case overturned traditional cognition. In the public impression, water injected meat mostly targets large livestock such as cattle, sheep, horses and pigs, and niche products such as bullfrogs are extremely rare. In fact, the cases of injecting water into turtle, yellow croaker and other fish have also been exposed before, but there are few such cases, the amount involved is small, and it is difficult to investigate and deal with, so it has not formed a great influence. Therefore, it is not difficult to see that there are various illegal methods of food safety, and the actual situation is far more than expected. On the other hand, the investigation and handling of this case has also brought a wake-up call to the regulatory authorities. Water injected meat has no specific object and scope, and many animal raw materials have the potential risk of being illegal and criminal. Therefore, we should not focus on the big and let go of the small, or take care of one and lose the other in terms of food safety, but should adhere to the principle of full coverage and normalization to avoid regulatory vacuum and management loopholes. At the same time, we should innovate the way of supervision and improve the efficiency of governance, and find a way to solve the problem in the aspect of "difficult to find". The punishment of bullfrog water injection improves the deterrent effect of safety supervision, which can not only improve public awareness and constantly change ideas while publicizing common sense, so as to create a social atmosphere of common participation, but also form Legal Popularization by drawing inferences from one instance, so that employees in the food industry can understand the law, fear and abide by the bottom line, and effectively curb the impulse of violations and crimes, So as to achieve the effect of source control.
