Hairy crab hormone excess? Is it artificially added to be indistinguishable?

Excess female hormone exists in the body of crabs? A few days ago, the Hong Kong branch of Swiss General Public Notary Co., Ltd. detected the Hong Kong market hairy crabs and discovered that a quarter of the samples contained estrogen. Three people a day would reach the safety limit recommended by the World Health Organization. When the news came out, many diners were worried. The reporters once called relevant industry associations and fishery experts. The current estrogen tests are still unable to distinguish whether they contain the banned statutory hormones or whether they are artificial additives. The Hong Kong Food and Environmental Hygiene Department said that this year's crabs have been tested for seasonal foods and the test results will be announced later.

Hong Kong: Satisfactory testing last year, announced later this year According to a report issued by the Hong Kong branch of the Swiss General Surveyor, the company purchased more than 30 hairy crab samples from the Hong Kong market. The results showed that 25% of the samples contained estrogen levels of gram per gram. Contains 15 ng or more, and the highest sample contains 100 ng per gram. According to the company’s researchers, the meat and cream of a hairy crab weighed about 10 grams and was calculated on the basis of WHO’s recommended daily maximum intake of estrogen per person. , has exceeded the safety standards. However, the staff also said that the detection methods they used are flawed. For example, whether or not estrogen is added manually requires further testing.

The reporter called the Hong Kong Food and Environmental Hygiene Department yesterday. According to the requirements of the Supervision and Administration of Inspection and Quarantine of Outbound Aquatic Animals issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, the supply of crabs in the Mainland must come from the farms registered by the entry-exit inspection and quarantine agencies in the Mainland. The FEHD will also send staff to inspect the Mainland supply of Hong Kong's hairy crab farms and confirm their production models, management methods and inspection and quarantine measures. In addition, the FEHD staff of the port quarantine station will check the hairy crabs sent to Hong Kong, check and collect the health certificates issued with the arrival of the batch of hairy crabs.

At the same time, the FEHD will also sample crabs and other crabs at the import, wholesale and retail levels for chemical and microbiological tests to ensure that crabs and other crabs can be eaten safely. The staff told the reporter: “Last year, the FEHD collected more than 110 samples of hairy crabs for chemical and microbiological tests. Chemical test items included the detection of veterinary drug residues, metal impurities, artificial hormones, coloring materials, and oxalic acid. Microbiological tests tested parasites. All were tested. Satisfactory results." He revealed that the investigation of seasonal food for crabs this year has also been completed and the results will be announced later.

Industry Association: There is no problem of excessive hormones Yang Weilong, chairman of the Yangcheng Lake Hairy Crab Industry Association in Suzhou, said that it did not respond for the time being, but currently Yangcheng Lake hairy crabs have been tested by industry and commerce and quality supervision departments at all links such as breeding and effluent, and safety should not be a problem. . "The hairy crabs are listed by the Jiangsu Provincial Bureau of Quality Supervision. If they are to be exported, they will be subject to inspections and inspections by the Jiangsu Entry-Exit Inspection and Quarantine Bureau. There has never been a problem of excessive hormone levels." Yang Weilong said that due to the large area of ​​Yangcheng Lake, the relevant The department will designate the breeding area for management in advance. At the same time, the farmers also signed a safety production commitment system, and established management systems such as production and farming ledgers. In an interview earlier, Yang Weilong once said that this year's Yangcheng Lake has the best water environment for many years.

It is understood that on the basis of the above, the export of hairy crabs will be tested through dozens of projects. However, whether these testing items include estrogen testing, staff of Jiangsu Entry-Exit Inspection and Quarantine Bureau did not give a clear reply. There are media reports here that test items and standards will be announced in the near future.

Expert: Excessive estrogen may cause harm to the human body. “The key issue for hairy crabs is the problem of estrogen. The key is to identify whether it is its own cause or is affected by humans.” Bao Baolong, professor at Shanghai Ocean University’s College of Fisheries and Life, said in an interview that eating Excessive estrogen-containing aquatic products will definitely cause harm to the human body.

If it is artificially added, feed is the only way. "Because hairy crabs are crustaceans, they are difficult to add by injection and can only be added through feed." Associate Professor of Shanghai Ocean University and Dr. Qu Xiancheng of the Fisheries Department of Hokkaido University in Japan told the reporter. He is concerned that artificial addition of estrogen may also cause female hairy crabs to become female, and eating these crabs will be endangered. “Estrogen is an endocrine disruptor. Excessive estrogen can affect the human reproductive system and disrupt the secretion of pituitary hormones and thyroid hormones. At the same time, it is more harmful to special populations. It can seriously cause girls to become precocious and boys to have female sexual characteristics. ."
