Recently, CCTV reporters bought edible ice cubes from McDonald's, KFC and Kungfu in Chongwenmen, Beijing, sent them to Beijing Physical and Chemical Center for testing, and took samples of toilet water in the toilet of the Physical and Chemical Center for comparison. The test results show that the number of colonies in KFC and Kungfu ice cubes is higher than the national standard and several times higher than that in toilet water. In this regard, KFC China issued an apology message. Huaxi Dushi Bao reporter visited several KFC stores in Chengdu yesterday and found that ice drinks are still on sale.
The total number of ice colonies exceeded the national standard.
The results showed that the coliform bacteria, staphylococcus aureus and salmonella of ice cubes in three fast food restaurants met the national standard, but the total number of ice colonies in McDonald's was 1.21/ml, which was higher than the national standard and lower than the toilet water. The total number of colonies in real kung fu ice cubes is 911/ml, which is 8 times higher than the national standard and 5 times higher than the toilet water. The total number of colonies in KFC's edible ice cubes is as high as 2111/ml, which is 1.9 times higher than the national standard and 1.2 times higher than the toilet water.
After the program was broadcast, it caused an uproar. Netizens said that they were "disgusting" and "rare life, away from ice". Another employee of a fast food restaurant said: "After CCTV was exposed, the store received a notice to clean the ice storage tank carefully. If the ice in our store is pumped, it will definitely explode KFC!"
KFC apologizes McDonald's self-inspection
Yesterday morning, only four hours after the program was broadcast, KFC China issued an apology message. KFC said that it is very sorry for this situation. The quality control department of the company has gone to the restaurant to understand the situation and supervise the restaurant to clean and disinfect the ice maker and related equipment strictly according to the standards immediately. McDonald's, which was also found to have exceeded the number of colonies, also announced that it had carried out self-inspection at the first time, including the related equipment and operating specifications of ice cubes.
Kungfu also said yesterday that it had immediately urged the exposed restaurants to clean and disinfect the ice-making equipment again according to the standards, and further investigation and understanding will be made in the future.
The local
salesperson said that he didn't receive the notice to stop selling
Yesterday afternoon, Huaxi Dushi Bao reporter visited several KFC stores in Chengdu and found that most of the drinks ordered by customers contained ice cubes.
At the KFC store in Qingjiang East Road, Chengdu, the reporter asked the salesperson about the fact that the bacteria in the ice cubes exposed by CCTV exceeded the standard. The salesperson said that he did not know and did not receive a notice to stop selling ice cubes. Customer Mr. Luo said: "Although the colony exceeded the standard in a store in Beijing, I also hope that Chengdu stores will carry out self-inspection to make consumers feel at ease."
61% of fast food restaurants in Britain have exceeded the standard of bacteria in ice cubes
The Daily Mail of Britain also conducted a survey recently. More than 61% of the ice cubes provided by restaurant chains in Britain have more bacteria than toilet water. Experts warned that home-made ice cubes may also have bacteria exceeding the standard. He suggested that as long as it is edible, the water for making ice should be cold boiled water after boiling. In addition, bottled water is not suitable for making ice, because it is difficult to ensure that its microorganisms do not exceed the standard.
British media reported recently that more than 61% of the food and beverage chains in the UK provided more bacteria in ice cubes than the standard, even more than the water taken from the toilet tank.
According to the report, investigators obtained ice samples from some restaurant chains in Britain, kept them in sterile bags, and then asked an environmental professional to take samples from the toilet water tanks of the same store, and kept them in the refrigerator and sent them to the laboratory for testing.
There are over 11 chain stores including McDonald's, Burger King, Starbucks and KFC. In the environment of 22℃ and 37℃, the number of pathogens and total bacteria in the samples were detected. The number of bacteria in the ice samples of six chain stores was higher than that in the toilet water tank.
experts believe that the ice is polluted or caused by "environmental factors", such as a dirty ice machine.
In other words, the staff of fast food restaurants clean toilets more frequently than the ice machine.
The contamination of ice cubes may also be caused by "human factors", such as the staff not washing their hands carefully.
Let's take a look at a group of comments from Netease News.
The national standard requires that edible ice cubes should be "immediately inspected" and kept for no more than three hours, during which they should be kept in a frozen and sterile environment. CCTV reporters brought the ice cubes from Chongwenmen, Dongcheng District, Beijing to the physical and chemical center in Xicheng District, Beijing, which may not meet the requirements of the national standard to preserve the ice cubes.
The national standard of Microbiological Inspection of Food Hygiene, Inspection of Frozen Drinks and Drinks has strict requirements not only on sampling instruments and processes, but also on the preservation status and time limit of samples. After the samples are taken, they should be sent for inspection immediately. If they cannot be inspected immediately, they should be sent to the food hygiene microbiology laboratory as soon as possible, and the time should not exceed three hours at most.
if the journey is far away, the ice should be stored in a special aseptic ice cylinder, refrigerator ice box, low-temperature refrigerator or dry ice insulation box (the box can be kept below 1℃ with dry ice). CCTV bought ice cubes from three fast food restaurants in Chongwenmen, located in South Second Ring Road, Dongcheng District, Beijing, put them in unsterilized containers on the spot, and then took them to Beijing Physical and Chemical Analysis and Testing Center, located in West Third Ring Road, Xicheng District for testing. This journey takes about half an hour even if the traffic is completely smooth. It is not known whether CCTV reporters have prepared sterile ice buckets or dry ice insulation boxes to store ice samples in the car.
if the number of colonies exceeds 151, it is not necessarily that the toilet water is dirty
? There are 5611 colonies in human intestine, and the current national standard of light industry stipulates that the upper limit of the number of colonies in hand sanitizer per milliliter is 1111, but it cannot be said that "the human body is dirtier than the toilet", "hand sanitizer is dirtier than the toilet water by six or seven times"
and "comparing the toilet" is grandstanding
? The investigation report requires objectivity and realism, and it is not helpful to evaluate the interviewed object by grandstanding and generalizing the report < P > It is difficult to say that the final result is reasonable and true by collecting samples for health testing with procedures that bring secondary pollution and conveying information unilaterally with sensational headlines. It should be said that the incident of "ice cubes in fast food restaurants are dirty over toilet water" was a failure when CCTV interviewed social news.
? CCTV uses grandstanding to evaluate the interview object in a general way, which can neither objectively reflect the real social reality nor help solve the real problems that may exist in food hygiene. It is an important social responsibility of TV stations to investigate and expose, but the more they investigate the facts that have an important impact on public interests, the more they need the media to do it step by step in the investigation process. Otherwise, investigating unannounced visits is no different from framing. No matter how good the original intention is, it can't objectively help the public understand the facts.
It's unprofessional and imprecise for investigators to blame people with national standards but not to take samples with national standards.
? CCTV blames fast food restaurants with national standards instead of standardizing its own sampling process. Either it deliberately sets a trap to plant various fast food restaurants and deceive the audience, or it has no scientific and rigorous working attitude in some professional fields, which is a typical case of unprofessional, unscientific and imprecise CCTV investigation and reporting. This proves that CCTV investigative reporters have much room for improvement in their professional quality. In highly professional reports, only with scientific spirit and rigorous attitude can we help the public clarify the truth. Otherwise, the report can not bring the truth to the audience, but create an illusion for the audience.
? In view of the news that ice cubes in fast food restaurants are not as good as toilet water, Dr. Kai Zhong, an associate researcher at the National Food Safety Risk Assessment Center, thinks that the analogy between ice cubes and toilet water is somewhat sensational. Toilet water that is washed repeatedly and not mixed with excrement and urine is tap water, and there is residual chlorine in tap water, and of course there are few bacteria. The total number of colonies in ice cubes will exceed the standard. According to Kai Zhong's analysis, there are many links in the raw materials for making edible ice that may be polluted, so citizens do not need to "talk about the color change of ice"
