The total number of ice colonies exceeds the national standard.
The results showed that the coliform bacteria, Staphylococcus aureus and Salmonella in the ice cubes of three fast food restaurants all met the national standards, but the total number of colonies in the ice cubes of McDonald's was 120 /ml, which was higher than the national standards and lower than the toilet water. The total number of colonies in real kung fu ice cubes is 900 /ml, which is 8 times higher than the national standard and 5 times higher than toilet water. The total number of colonies in KFC's edible ice cubes is as high as 2000 /ml, which is 19 times higher than the national standard and 12 times higher than toilet water.
After the program was broadcast, it caused an uproar. Netizens have expressed "disgusting" and "life is rare, stay away from the ice". An employee of another fast food restaurant said: "After CCTV was exposed, the store received a notice to carefully clean the ice storage tank. If the ice in our store is pumped out, it will definitely blow up KFC! "
Kfc apologizes McDonald's self-inspection
Yesterday morning, just four hours after the 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 immediately clean and disinfect the ice maker and related equipment in strict accordance with the standards. McDonald's, which was also found to have exceeded the total number of colonies, also announced a self-inspection at the first time, including the related equipment and operating specifications of ice cubes.
Kungfu also said yesterday that it has immediately urged the exposed restaurants to clean and disinfect the ice-making equipment again according to the standards, and will further investigate and understand this matter in the future.

The salesperson said that he did not receive the notice of suspension of sales.
Yesterday afternoon, Huaxi Daily reporter visited several KFC stores in Chengdu and found that most of the drinks ordered by customers contained ice cubes.
At KFC's store in Qingjiang East Road, Chengdu, the reporter asked the salesperson about CCTV's exposure of ice bacteria exceeding the standard. The salesperson said that he didn't know and didn't receive a notice to stop selling ice cubes. Customer Mr. Luo said: "Although the colony of a store in Beijing exceeds the standard, I also hope that the Chengdu store will conduct self-inspection to reassure consumers."
60% of fast food restaurants in Britain have exceeded the standard.
The British "Daily Mail" also conducted a survey recently. More than 60% of the ice cubes provided by British chain restaurants have more bacteria than toilet water. Experts warn that there may be bacteria exceeding the standard in homemade ice cubes. He suggested that as long as it is edible, the water for making ice should be boiled cold water. 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 recently reported that more than 60% restaurant chains in the UK provided more bacteria in the ice cubes, even more than the water taken from the toilet tank.
According to the report, the investigators obtained ice samples from some chain restaurants in Britain and kept them in sterile bags. Then they asked an environmental professional to take samples from the toilet tank of the same store, kept them in the refrigerator and sent them to the laboratory for testing.
Chain store brands include McDonald's, Burger King, Starbucks, KFC and so on 10. The total number of pathogenic bacteria and bacteria in the sample was detected at 22℃ and 37℃. The number of ice-like bacteria in six chain stores is higher than that in toilet tanks.
Experts believe that ice cubes are polluted or caused by "environmental factors", such as dirty ice machines.
In other words, the staff of fast food restaurants clean toilets more frequently than ice makers.
The pollution of ice may also be caused by "human factors", such as the staff not washing their hands carefully.
Let's look at a group of comments from Netease News.
National standards require that edible ice cubes should be "immediately collected and inspected" and stored for no more than three hours, during which they should be stored 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 national standards for ice cubes preservation.
The national standard "Microbiological Inspection of Food Hygiene" "Inspection of Frozen Drinks and Drinks" not only has strict requirements on sampling instruments and processes, but also has clear requirements on the preservation status and duration of samples. After sampling, it should be sent for inspection immediately. If it cannot be tested immediately, it 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 long, the ice should be stored in a special aseptic ice tank, refrigerator ice box, low-temperature refrigerator, or dry ice incubator (there is dry ice in the box to keep it below 0℃). CCTV bought ice cubes from three fast food restaurants in Chongwenmen, located in the South Second Ring Road, Dongcheng District, Beijing, put them in unsterilized containers on the spot, and then took them to the Beijing Physical and Chemical Analysis and Testing Center in the West Third Ring Road, Xicheng District for testing. Even if the traffic is completely unblocked, the journey will take about half an hour. It is not known whether CCTV reporters have prepared sterile ice buckets or dry ice incubators to store the ice samples in the car.
When the number of colonies exceeds 150, toilet water may not be dirty.
? The number of colonies in human intestine is 5600, and the current national standard of light industry stipulates that the upper limit of the number of colonies per milliliter of hand sanitizer is 1000, but it cannot be said that "the human body is dirtier than the toilet water" or "the hand sanitizer is dirtier than six or seven times".
"Than the toilet" is grandstanding.
? Investigation reports require objectivity and seeking truth from facts, and grandstanding and partial evaluation of interviewees are not conducive to seeking truth from facts.
It is difficult to say that the final result is reasonable and true by using the program that brings secondary pollution to collect samples for health testing and unilaterally transmitting information with sensational headlines. It should be said that CCTV's interview with the social news "The ice cubes in fast food restaurants are dirtier than toilet water" is a failure.
? CCTV's general evaluation of interviewees by grandstanding can neither objectively reflect the real social reality, nor help to solve the practical problems that may exist in food hygiene. Investigation and exposure is an important social responsibility of TV stations, but the more you investigate the facts that have an important impact on public interests, the more you need the media to do it step by step in the investigation process. Otherwise, investigating unannounced visits is tantamount to framing. No matter how good the original intention is, it can't objectively help the public understand the facts.
It is unprofessional and imprecise for investigators to criticize people with national standards but not to sample them with national standards.
? CCTV blames fast food restaurants with national standards instead of standardizing its own sampling process. Either deliberately set traps to plant various fast food restaurants to deceive the audience, or there is no scientific and rigorous work attitude in some professional fields, which is a typical case of unprofessional, unscientific and imprecise CCTV investigation and reporting. This proves that the professional quality of CCTV investigative reporters still has a lot of room for improvement. 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 truth to the audience, but creates 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. Repeatedly washing toilet water without feces is tap water, which has residual chlorine and, of course, less bacteria. The total number of colonies in the ice will exceed the standard. Kai Zhong analyzed that there are many links in the raw materials of edible ice that may be polluted, and there is no need for the public to "talk about the color change of ice"
