Rice, Clenbuterol, Diao Baikuai the frequent, almost three meals a day so that the people who are on tenterhooks. However, the Ministry of Health published the other day in the first quarter of 2008 samples of food hygiene supervision and detection of specific information, you may be able to make on food hygiene and safety concerns about some of the slightly off.
In the first quarter of 2008, the Ministry of Health of the Organization of Hebei, Hunan, Sichuan, Shanghai, Guangxi, and other 21 provinces, autonomous regions and municipalities on the market for health food sampling, and some of the pollutants in the food market, additives, heavy metals Some of the indicators of pollutants such as a special testing. Sampling and testing showed that one quarter of China's food hygiene in good condition.
It is reported that 9 of the sample 239 kinds of categories of food products, 232 kinds of qualified, qualified rate of 97.1 percent. Bottled water a total of 16 varieties of sampling, testing projects for the total number of bacteria, E. coli, yeast and mold, according to the state "pure bottled drinking water health standards" to judge all qualified. Food samples were all qualified monosodium glutamate, preserved vegetables, such as pasteurized milk. Milk drinks, frozen drinks, calcium to increase bone mineral density or type of health food can not reach all qualified, but the passing rate is quite high, reaching 93.8%, 80% and 97.9%.
In addition, additives, heavy metals, such as 13 kinds of pollutants commonly detected specific passing rate higher. Detection of 583 samples, 561 passing, the passing rate of 96.2 percent. The crabs, the detection of heavy metals, 10 samples of all qualified. 40 of jelly, cakes, bread, pickles preservatives testing samples of all qualified; on the market for 59 kinds of soy-alcohol test results are all qualified.
The discovery of the unqualified products, products to the health administrative departments have investigated and dealt with in accordance with the law carried out. The Ministry of Health said that in order to improve the effectiveness of supervision and management, all localities should take full advantage of the news media and electronic networks, announced in a timely manner the problems identified, and their integration into bad faith business files, to increase the frequency of supervision and punishment, as a warning to the production of illegal operators To protect the interests of consumers.

Traditional and modern fast-food restaurants are essentially different. In comparison, traditional-style restaurant is a workshop, mainly to manual processing of a single shop, with management experience and modern civilization to the modern-style fast food is the definition of scale, standardization and modernization of relying on the chain management system. For example, both the Chinese snack foods, fast food or cuisine, both have a long history. Say that snack bars, the dumplings, pies, noodles, steamed stuffed bun, etc., which is not several hundred years of history? Lunch so many chicken-based material to the Lazi chicken, Wenchangji, Baiqieji, Shouxi chicken, stewed native chickens, and so on, which one tastes better than many of the Kentucky delicious peppery blue cheese dressing? But why now, Deng Daiyazhitang still difficult? The key lies not form standardization, standardization, and every restaurant to a Heart Association and found that many do not repeat mistakes of the matter.

Traditional plant breeding involves crossing varieties of the same species in ways they could cross naturally. For example, disease-resistant varieties of wheat have been crossed with high-yield wheat to combine these properties. This type of natural gene exchange is safe and fairly predictable．
Genetic engineering（GE）involves exchanging genes between unrelated species that cannot naturally exchange genes with each other. GE can involve the exchange of genes between vastly different species―e.g. putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes. It is possible that a scorpion toxin gene, even when it is in maize DNA, will still get the organism to produce scorpion toxin―but what other effects may it have in this alien environment? We are already seeing this problem―adding human growth hormone genes to pigs certainly makes them grow―but it also gives them arthritis and makes them cross-eyed, which was entirely unpredictable．
It will be obvious, for example, that the gene for human intelligence will not have the same effect if inserted into cabbage DNA as it had in human DNA―but what side-effect would it have？In other words, is GM food safe to eat？The answer is that nobody knows because long-term tests have not been carried out.
Companies wanting a GM product approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests. Monsanto’s soya beans were apparently fed to fish for10 weeks before being approved. There was no requirement for independent testing, for long-term testing, for testing on humans or testing for specific dangers to children or allergic people.
The current position of the UK Government is that “There is no evidence of long-term dangers from GM foods.” In the US, the American Food and Drug Administration is currently being prosecuted for covering up research that suggested possible risks from GM foods.
