Test background Therefore, Greenpeace decided to sample and conduct pesticide residue and genetic testing at the supermarket to see whether supermarkets have taken adequate measures to ensure food safety. Sample details Greenpeace was between February and March 2009 in Beijing, Shanghai, Guangzhou and Shenzhen. Lotus Lotus [Silk Lotus Shopping Center has been renamed the Lotus Lotus Shopping Centre. Currently, the stores are gradually being renamed. Given that Lotus is more familiar to consumers, this article collectively referred to the Lotus Shopping Mall as Lotus Lotus, China Resources Vanguard and Wal-Mart. They purchased papaya samples and sent them to an independent international authoritative testing organization for the detection of genetically modified components. The results showed that the domestically produced papayas sold by major supermarkets were all genetically modified papayas, and only the Philippines imported papayas sold by Wal-Mart’s Zhichun Road branch in Beijing were non-transgenic papayas. See the table below for details. Sampling site Sampling time Origin (according to product label or supermarket employee) Test results Yichu Lotus, Guangzhou 2009-02-14 Guangdong Positive China Resources Vanguard, Shenzhen 2009-02-15 Guangdong Positive Walmart, Shenzhen 2009-02-15 Guangdong Positive Wal-Mart, Beijing 2009-03-05 Philippines imports negative Lotus Lotus, Shanghai 2009-03-21 Fujian Positive Walmart, Shanghai 2009-03-21 Hainan positive Yichu Lotus, Beijing 2009-03-24 Hainan positive China Resources Vanguard, Beijing 2009-03-24 Uncertain Positive Wal-Mart, Beijing 2009-03-24 Hainan positive When Greenpeace sampled, almost all papayas sold in supermarkets were placed in bulk without any logo. If consumers want to buy non-GM papaya, there is no choice. Supermarket responsibilities Greenpeace's genetically modified papaya test results showed that the domestically produced papayas sold by Lotus Lotus, China Resources Vanguard and Wal-Mart are all genetically modified papayas. Supermarkets are the main channel for more and more consumers to buy fresh vegetables and fruits. Consumers think that supermarkets have the responsibility to provide consumers with safe and reliable foods to ensure food safety. This includes ensuring that the agricultural products sold do not contain pesticide residues. It also includes not selling GM foods. The long-term safety of genetically modified foods, including papaya, has not been established, and consumers have also made clear that they have chosen non-genetically modified products. At the same time, genetically modified crops are a hidden danger to the environment. The Greenpeace test results show that Lotus, China Resources Vanguard and Wal-Mart sell GM papaya to consumers. This is not only a denial of consumer refusal to GM food, it may also pose a threat to food safety and the environment. The problems revealed by the results of this test are similar to those revealed by Greenpeace's recent pesticide residue testing. Greenpeace conducted pesticide residue testing on fresh fruits and vegetables sold in domestic supermarkets at the end of 2008 and early 2009. The results showed that various pesticide residues were detected, and the problem of mixed pesticide residues was serious, which may cause consumer health and environmental problems. Serious impact. Of the 45 samples detected, a total of 40 samples detected 50 pesticides remaining, and the mixed pesticide residue was even more severe. A total of 34 samples contained at least 3 different pesticides, of which 25 contained at least 5 different pesticides, and 5 samples even contained more than 10 different pesticide residues. All five samples were from supermarkets, including cowpea (11 species) and strawberries (13 species) in Wal-Mart supermarkets, cowpea (11 species) from Lotus, and Huarun Wanjia (12 species) and cucumber (13 species). ). Greenpeace informed consumers of the results of consumer surveys and appealed to supermarkets to respond to the needs of consumers. The results of these two tests show that supermarkets such as Lotus, China Resources Vanguard, and Wal-Mart have not been able to supervise the supply of fresh fruits and vegetables, and have not been able to assume the responsibility of protecting consumers' food safety, and have failed to meet consumer demands. However, as leaders of the industry, Lotus, China Resources Vanguard and Wal-Mart should set an example as soon as possible, take measures to ensure food safety for consumers, and lead the entire supermarket industry to shoulder its due responsibilities. Supermarkets need to be aware of their responsibilities and take measures to assure measures as soon as possible. For genetically modified foods, including genetically modified papaya, Greenpeace appeals to supermarkets to ensure that their own branded processed food does not use genetically modified raw materials and does not sell genetically modified fresh foods (such as papaya) for the health and environment of consumers. In response to the problem of pesticide residues, supermarkets need to commit to reducing the amount of pesticides used in the fruits and vegetables they sell, and introduce timetables and specific measures to help their suppliers and producers reduce the use of pesticides and use more ecological methods to control pests and diseases. Supermarkets also need to gradually increase the supply of ecological agricultural products. At the same time, supermarkets also need an effective supply chain monitoring system, including the establishment of traceability mechanisms to strengthen the detection of genetically modified and pesticide residues, and strengthen the management of suppliers and supply chains (for example, if problems are detected, the Punitive provisions, etc.), and to ensure that consumers are able to keep abreast of the situation regarding pesticide residues. Genetically modified papaya related background In 1998, the first commercial transgenic papayas in the world appeared in Hawaii, USA. This genetically modified papaya was transformed into a gene of Papaya Ringspot virus (PRSV) in order to make papaya resistant to this virus. According to the 2006 survey, after many years of cultivation, the local organic papaya cultivation suffered serious damage due to the large-scale contamination of non-genetically modified and organic papaya in genetically modified papaya. Japan, which is the main exporter of Hawaiian papaya, refuses to approve the import application for this genetically modified papaya due to food safety. At the same time, Japan requires all papayas exported to Japan from Hawaii to undergo non-genetic testing. The entire papaya planting industry in Hawaii was also affected. According to data from 2006, compared with 1998, the overall planting area of ​​papaya decreased by 28%, and the average household per gram of papaya income per household decreased by 35% [Greenpeace Internaltion (May 2006), The Failure of GE Papaya In Hawaii. ]. Since 1998, the U.S. government has been lobbying the Japanese government to approve the import of this GM papaya variety, but the Japanese government has been concerned about the food safety of GM Papaya and requested the U.S. government to provide more evidence to prove its safety. So far the Japanese government It is still considered that the food safety of genetically modified papaya is doubtful and has not been approved for the import of genetically modified papaya. In 2004, the Hong Kong regional government obtained some papaya seeds from an agricultural research institute in mainland China and distributed them to local farmers (including organic farmers) for planting, and subsequently discovered that the relevant seeds were genetically modified. Greenpeace further detected and investigated the incident and actively assisted local organic farmers in removing and isolating the genetically modified papaya and preventing the contamination of other farmland. In July 2006, the Ministry of Agriculture of China approved the development of a papaya-resistant papaya ring spot virus-transgenic papaya by the South China Agricultural University in Guangzhou, allowing the variety to be planted in Guangdong Province [Approval No. 001 No. 2006, 2006, validity period. From July 20, 2006 to July 20, 2011], but the control of genetic contamination is worrying. Potential Hazards of Genetically Modified Papaya The process of transgenes may have unintended effects on organisms, and the long-term safety of genetically modified foods is inconclusive. Scientific research shows that genetically modified papaya may cause allergic reactions. The introduction of foreign genes for disease resistance will produce a protein that is very similar to proteins that may cause allergic reactions. More research is needed to ensure the food safety of genetically modified papaya. It is in view of this concern that the Japanese government has not approved the import license for GM papaya in the United States. Transgenic crops, including genetically modified papaya, may also pose environmental hazards, including threats to biodiversity, impacts from non-target organisms, impact on other species through genetic drift, and genetically modified super weeds. Transgenic papaya-resistant papaya papaya can only resist one virus, but papayas can be threatened by various viruses or insects. Papaya growers still need to use pesticides to control other diseases and pests. to sum up The Greenpeace test found that a large number of genetically modified papayas are being sold at Lotus, China Resources Vanguard and Wal-Mart. Consumers do not know whether the purchased papaya is non-transgenic. Supermarkets urgently need to take measures to respect the rights and interests of consumers, immediately stop the sale of genetically modified papayas, investigate the suppliers of related products, strengthen the inspection of other papaya suppliers, establish a sound supplier and manufacturer monitoring system, and ensure the consumers Can be assured of non-genetically modified papaya. A comprehensive supplier and manufacturer monitoring system can also help supermarkets better detect pesticide residues, control the use of pesticides, and ensure that consumers' food does not contain pesticide residues.

Lianjie.com News: People use food as their food source. The safety of supermarket food as a major food sales channel has always been the focus of consumers. In 2007, Greenpeace entrusted a survey conducted by Ipsos (China) Market Research and Consulting Co., Ltd. to find that 65% of respondents explicitly selected non-genetically modified foods (including fresh and processed foods) and consumers who purchased foods in supermarkets. Among them, 70% believe that supermarkets should establish a pesticide residue monitoring system.
