1. In 2002, Henan arsenic exceeded the standard event
In 2002, Wang Lianxin of Dongxinzhuang, Chengguan Town, Huixian City, Henan Province, had been raising pigs for more than 10 years. In February, more than 70 pigs he had raised died one after another. Wang suspected that it might be a problem with feed. "The piglets improved after one day." At the same time, another pig farmer in the same village, Feng Jianzhong, also sent more than 40 heads. The news of the pig dying. The two household feeds are the same brand of the same manufacturer. On February 28 of that year, Wang Lianxin took the pig feed and went to the Zhengzhou Feed Product Quality Supervision and Inspection Station to test the feed. The results show that the arsenic content of the batch of feed is as high as 82.56 mg per kilogram...
2, 2003, City organic event
In late October 2003, a relatively rare disease of piglet stress death occurred in some villages in Nanjing and Pinghe in the suburbs of Ganzhou. The piglets trembled and even fell to the ground. After the follow-up analysis, it is believed that it is highly likely to be poisoned by organic cockroaches. Among the more serious ones, 10 pigs with 20 or 30 kilograms were raised. After feeding in the morning, 6 large pigs were caught and ready to go on the market. As a result, three pigs were found dead. The four piglets left in the column also died one. At the same time, several farmers in the same village who also fed the same feed also found one or two deaths in their respective pig pens. The appearance of dead pigs has a certain degree of congestion, the ear leaves are blue-purple, and the abdomen can also see purple-red spots of different sizes. The necropsy showed only mild hemorrhage in the liver, partial infarction at the edge of the spleen, bleeding spots in the kidney, and gastrointestinal swelling. The disease materials and blood samples were sent to Zhangzhou for testing, and no pathogenic microorganisms were found. "
A few days later, a mountain village in Pinghe County also found the same abnormal disease. The 20-25 kg piglets suddenly hide under a squat during the feeding process and continue to tremble. It is recommended to add 914, Nicosu and other organic sputum preparations for treating Eperythrozoon in pigs. Unexpectedly, the symptoms have not been alleviated, but the piglets with strange diseases have become more. At this point, we suspect that it is organic. Therefore, it is recommended to immediately stop using the original self-contained powder and switch to full-price granules. After 1 week, the symptoms disappeared.
3, 2009 Yunnan arsenic over-standard event
On August 13, 2009, the Xuanwei City Administration of Industry and Commerce of Yunnan Province received a report: The pigs in a central pig storage base in the jurisdiction died one after another. The Industry and Commerce Bureau immediately sent staff to investigate and collect evidence. Liu Junyan, director of the base production plant, introduced that they chose a company's boar and sow compound feed, and began feeding at the end of April. Two months later, the pigs developed constipation, vomiting, conjunctival flushing, and congestion. After they called the relevant experts, they were treated under the guidance of experts. A week later, a large white boar without any symptoms and symptoms died suddenly, followed by bred sows and sows. They suspected that there was a problem with the feed and sampled it and sent it to the Qujing City Veterinary Drug Feed Inspection Institute for inspection. The Institute issued an inspection report on August 11th: the total arsenic content of 558 boars compound feed was 20.42 mg/kg, and the total arsenic content of 556 pregnant sow compound feed was 13.78 mg/kg, both exceeding the national limit of 2 mg/kg/ The standard of kilograms. The industrial and commercial case-handling personnel conducted further investigations to prove that the above situation was true. A number of samples and other materials were taken from the hairs and hooves of the dead pigs to the meat and internal organs, and sent to the Judicial Identification Center of the Yunnan Academy of Agricultural Sciences. The center then invited experts to form experts. The group, together with Xuanwei related departments and both parties, through field investigation, evaluation, laboratory and demonstration, concluded on October 13 that there is a causal relationship between the injury and death of the base pig and the feed it feeds!
4, 2013 Huangpu River dead pig rafting incident
In March 2013, a large number of floating dead pigs suddenly appeared in the waters of Songjiang section of Shanghai Haihuangpu River. The Shanghai quarantine department conducted information verification on some collected pig ear tags, and initially determined that the dead pigs came from the Jiaxing section of Zhejiang Province in the upper reaches of the Huangpu River. Before the quarantine agencies found the cause of a sudden onset of a large number of pigs, the "death cause" that various brains had come up with was already boiling. First, some netizens claimed to be "the catastrophic feed blame", and then the media claimed that "there was arsenic in the pig feed", but it earned enough eyeballs; the article said that "adding arsenic in the pig industry is no secret", but People feel a cold sweat: Is it true that the arsenic preparation feed is arsenic, and does the pork also contain arsenic? Can such pork be eaten? In response to public opinion and network questions, the Ministry of Agriculture commissioned the Shanghai Veterinary Feed Testing Institute to collect 30 samples of floating dead pigs salvaged from the Huangpu River and upstream waters for arsenic testing. The results of the March 20 test were published. All samples were published. No arsenic was detected.
