Dead pigs in Shanghai river: more than 6,000 carcasses found

Associated Press in Beijing
guardian.co.uk, Wednesday 13 March 2013 11.25 EDT

Hundreds more dead pigs have been recovered from the Huangpu river in Shanghai following the discovery of more than 2,800 floating carcasses earlier this week.

The find brings the total to more than 6,600 carcasses since last Friday.
...
On Wednesday, the Shanghai government said the city would continue to monitor water quality and test for viruses, including porcine circovirus, which is reported not to affect people. It said the city had disinfected some carcasses before either burying or incinerating them.

Dead pigs found in Chinese river exceeds 13,000

Updated 3 hours 46 minutes ago

The number of dead pigs found in a river running through the Chinese city of Shanghai has reached more than 13,000, with the precise origin of the pigs still unclear.
...
Shanghai said it had checked farms in its southwestern district of Songjiang, where the pigs were first detected, but found they were not to blame, the Shanghai Daily said.

Samples of the dead pigs have tested positive for porcine circovirus, a common swine disease that does not affect humans.

National Agriculture Ministry's chief veterinarian Yu Kangzhen said the higher mortality rate among pigs could be attributed to colder weather this spring and has ruled out an epidemic...

Two weeks on and still no answers on source of dead pigs found in Shanghai river

Theories and guesswork abound about source of the carcasses floating down to Shanghai

...
Wei Liang, director of the Youqiao village committee in Daqiao town, said it was impossible for thousands of dead pigs to float from Jiaxing to Shanghai, given that waterways in its villages are narrow, slow running and that barriers are erected in them to prevent dead pigs from floating downstream.

"Our barriers are made of bamboo bars and plastic grids. We have one or two people to patrol and clean up if there is any dead pig [found in the water]," he said, admitting that some villagers with "low ethics" tended to dump dead pigs into the water.

A pig breeder from Yangzhuang village in Xinfeng town said the mass dumping of dead pigs into the river was thanks to the recent disappearance of a black market in which illegal dealers bought dead pigs from farmers, processed them and sold the meat to restaurants.
...
Gu, the collector of dead pigs employed by Yongfeng's village, said the number of dead pigs had risen in the past two months because of illnesses including diarrhoea and coughing. He picked up about 40 dead pigs every day in his electric pedicab.
...
A farmer in Yongfeng village said the increase in pig deaths in the past few months could have been caused by environmental pollution from a chemical plant in the village that had recklessly released untreated fumes and waste water since it opened last year. Dramatic rises or falls in temperatures could also kill young pigs, she said.

Number of dead pigs pulled from Shanghai rivers nears 15,000

Agence France-Presse in Shanghai
Tuesday, 19 March, 2013 [Updated: 22:29]

The number of dead pigs found in a river which runs through Shanghai had reached nearly 15,000, officials and reports said on Tuesday, as a newspaper claimed the government was concealing the true tally.
...
Shanghai city workers retrieved 369 bodies from the Huangpu River on Monday, bringing the municipality?s total to 10,164 since the first were found earlier this month, the city government said in a statement.

Jiaxing in neighbouring Zhejiang province, whose farmers are accused by Shanghai of dumping the pigs into the river upstream, had found another 4,664 dead pigs, media reports said on Tuesday.
...
Jiaxing has insisted it was not the sole source of the dead hogs.

The Shanghai government repeated on Tuesday that treated water was within government-set standards, and said no meat from the dead pigs had been found in the city?s markets.

Jiaxing 70,000 dead pig behind the secret virus? Feed toxic?
2013-03-26 10:28:18 Views:552 Comments (0)Font Size: T T
Abstract: After a lapse of a half months, the Huangpu River drift pig incident "is still a mystery to be solved. The local dead pig underground industry chain is destroyed, not yet a dead pig processing system, 30 years of pig history of long-standing abuse of ills, a chain, and finally detonated the Huangpu River drift pig Masterpieces wonders.
　　Reported after a lapse of a half months, the Huangpu River drift pig event is still a mystery to be solved.
　　The 21st century Netcom field survey found that quite a lot of the story behind the large-scale pig deaths in Jiaxing, is the result of many factors accumulate.
　　The local dead pig underground industry chain is destroyed, not yet a dead pig processing system, the 30- year pig history ills long-standing abuse, interlocking and finally detonated the Huangpu River drift pig Masterpieces wonders.
Truth Behind reveal all the pain of the pig industry.

　　Fuse: the sudden disappearance of buyers
　　Since 2012 , the Zhu Lincun the pig farmers have suddenly found dead pig is not very good handle.
　　The one hand, the dead pigs in the village harmless most of the treatment pond pig infested; On the other hand, specializes in buying dead pigs buyers suddenly disappeared.
　　"Since last year, a gang of dead pigs received after being arrested, no one dares to collect dead pig." The villagers Zhang Limin, told the 21st Century Network.
　　11 January 2012 , Jiaxing sentencing a case involving 17 defendants.
　　From 2008 onwards, Fung Town, Jiaxing Samsung village of Dong Guoquan, Chen Xuezhong, Yao Jianping partner to set up illegal slaughterhouse in Dong Guoquan home. Subsequently, Dong Guoquan 3 people mustered more than an illegal slaughterhouse acquisition of dead pigs and processing, sales dead pork.
　　The illegal slaughterhouse handling of dead pigs astonishing.
　　Jiaxing Intermediate People's Court of verification in the period 1 January 2009 to 2011 years 11 months, the illegal slaughterhouse slaughtered dead pig 7.8 ten thousand, sales amounted to 876 million yuan.
　　Flows into the slaughterhouse of dead pigs and more from STUDIES IN Town, Xinfeng Town, the pig farmers. It is understood that the new Fengzhen the Jhulin Village and in Jiaxing largest pig base.
　　The Fengzhen herds pig 25 ten thousand, raising pigs 45 ten thousand, a village of bamboo forests account for about 14 ten thousand. General pig normal mortality rate of around 3% . "The new the Fengzhen vice mayor Huang Jun, told the 21st Century Network.
　　Calculated on this basis, Xinfeng a town only a year dead pig in the more than ten thousand. Well, these dead pigs are gone?
　　"Not construction the dead pig harmless treatment pond before, the dead pigs in accordance with the regulations are handled through the deeply buried." Wong military said.
　　However, a local source said that the 21st Century Network, "buried deep too much trouble, the general pig farmers would not be so dry, before the dead pig considerable part are sold to those specialized collection of dead pigs, then sent to the illegal slaughterhouse. "
　　In its view, this year's surge in the number of dead pigs, one of the reasons is that the disappearance of the "underground industry".
　　"Now there is no buyer, dead pig is not a place for the natural number of arbitrarily discarded phenomenon throw in the river is the most convenient."
　　According to its introduction, some on the scale of a dead pig traders and illegal slaughterhouse cold storage, because it may be some people directly to the acquisition of the dead pigs are thrown out. "
　　The similar dead pig underground trading in the industry, no longer a secret.
　　21 Century Network contacted a few pig farmers in Shandong and Jilin According to them, there have been no similar Zhejiang such a dead pig harmless treatment pond treatment, most of them rely on farmers consciously. "Pig buried or thrown, and will be able to sell more than 50 pounds on the money, ten to the dozens of pieces ranging. "
　　But they also said that two years increasingly stringent regulatory, dead pig transaction has been greatly affected.
　　In fact, in addition to the underground trading and the random throwing pigs, these dead pigs this the better path.
　　In 2011 , the Ministry of Agriculture has issued a special document stipulates that if the pig pig farmers appear unnatural deaths given a subsidy of 80 dollars. Period aimed at economic divert farmers to deal with the dead pig, but in fact, this subsidy policies are not put in place in accordance with the normal way.
　　Zhejiang Province issued on subsidies by App documents to handle per head of 80 million standard grant basis to focus on the funds to be allocated to the operating units. Have their own processing capabilities are generally large pig, focus on all policy sectors in the operating, and the casual farmers do not even know this part of the subsidies.
　　To landless buried the plight of the pig
　　In fact, as early as before the incident was exposed, "dead pig floating" phenomenon in Zhejiang, Shanghai and other regions have existed. Just the small number did not attract media attention.
　　Local villagers, throwing dead pigs into the water a longer normal thing.
　　"If the the Whose pigsty dead pig, who would go to close ah."
　　Because the local rivers, throwing dead pigs into the water is not easily found, as the illegal acquisition of the reduction of the dead pig behavior, farmers can easily think of this approach.
　　Jiaxing municipal government in order to put an end to this phenomenon long before the establishment of a dead pig processing system. First, establish a lot of dead pigs piled up points, the villagers the handling of dead pigs can choose to self-threw and call home collect two ways. Second, the village hand three times early in the evening to the various dump sites collect dead pig, then unified transport to the the dead pig harmless treatment pond processing.
　　Even so, the villagers still did not develop the habit of norms deal with dead pigs.
　　The xinfengzhen dead pigs into the plight of landless buried moment
　　According to the net in the 21st century to understand, since 2009 began to promote a dead pig harmless treatment pond, Jiaxing has built 573 harmless disposal point.
　　A treatment pond year processing capacity of 40 tons. " yellow army.
100 pounds calculated for 　　each dead pig , years processing the dead pigs capacity about 800 head, and so calculate the annual handling of dead pigs of Jiaxing City, 573 treatment pond capacity of 45.84 ten thousand, far more than Jiaxing 22.02 ten thousand pigs normal The number of deaths ( 2012 Jiaxing City, the number of breeding pigs 734 million head, the normal mortality rate of 3% ).
　　But the reality is not the case.
　　According to Huang Jun, processing pool is divided into two types, one is government-funded construction, a large farming funded self. "Only the government-funded treatment pond is opening up the the farmers self treatment ponds generally smaller and mostly for personal use."
　　Stand-alone treatment pond for now, farmers accounted for the majority of example xinfengzhen, the town is now a total of 112 a treatment pond , which self-built 72 large farming , government funded construction 40 .
　　According to the government-funded and self farmers to calculate the proportion of 1 : 3 , the actual dead pig handling capacity of only 12 million people.
　　In Jiaxing, the proportion of the scale of farming in less than 100 head of retail in more than 80% , which means that, Jiaxing and do not have enough hardware facilities to digest the local dead pig.
　　This contradiction is more apparent after the dead pig the underground industry chain is destroyed. Many harmless treatment pond already "pig-infested", the Zhu Lincun processing pool only one not yet saturated.
　　Apart the the dead pig digestive local xinfengzhen would also like to bear the pressure of close to local farmers dead pig.
　　"These dead pig is not completely the town, there are many local factories, some workers outside the town itself is home raising some pigs, the way to put dead pigs also brought over." New the Fengzhen a government The staff said.
　　According to to Jiaxing local media reports, 1 month, 2 months the only Zhu Lincun dead pig number of up to 1 million 8 one thousand Jiaxing municipal government said the number of dead pigs in Jiaxing City , 2013 has reached 700 ten thousand.
　　This number is far more than the existing local processing power, dead pigs into the plight of landless buried moment.
　　"Harmless treatment pond by anaerobic fermentation technology deal with dead pig, a pig processing cycle in about six months, the big pig in a year or so." Yellow army. The drawbacks of such a way that the processing cycle is too long, it will cause problems if encountered in large-scale pig death phenomenon.
　　According to Huang Jun, in order to deal with the problem of dead pigs landless buried, Jiaxing, Zhejiang inputs in this regard is still increasing, "the town every year to increase the number of treatment pond, this year's planned new 11 treatment pond. In addition, this year also voted to build a wet plant, dead pigs through industrialization means to solve problems, project investment in 1700 million of 12 months is expected to put into production. "
　　Dead pig Mystery
　　Smashed the dead pig underground industrial chain, and dead pig processing capabilities temporary shortage caused the direct cause of the Huangpu River drift pig event. But the real cause of death for the dead pig is still confusing normal death, freeze to death theory, classical swine fever, "arsenic" theory, the cause of death still a mystery to be solved.
　　After the media briefing, Jiaxing City Vice Mayor Zhao Shumei the main reason of the dead pig summed up in two points: 1. Jiaxing the overall pig farming large, small-scale, high-density, small-scale farmers poor feeding and management level throughout the survival The farm rate relatively high management level is low, normal death absolutely large. Last winter and spring temperatures lower pig the antifreeze weak, easy incidence of death, higher piglet mortality.
　　Jiaxing official will be a large number of pig deaths attributed to "normal death" and "freeze to death", but this conclusion and failed to get public recognition.
　　"Unlikely to freeze to death, pig swells more than 10 days, and generally will not freeze to death. salvaged from the dead pigs to see, many of them large. "Shandong above a farmers told 21 Century Network.
　　"If it is normal deaths, the proportion of high and should be the result of certain infectious diseases, not necessarily swine fever so large breeding density, general infectious disease also cause mass death of the pig."
　　According to its introduction, there is a saying in the aquaculture industry, the longer of species, pigs can not nurture. "If a pig is a continuous raise a pig, a variety of viruses accumulated up easily formed to generate a new type of virus resistance and gene mutation, and difficult to treat, even if disinfection is not OK. "
　　Xinfengzhen have a history of 30 years of breeding, more than 7 percent of the farmers in the pig, the pressure in this respect.
　　"Especially in the past few years, the pig is more difficult to support, and the one hand, pig, pig density is very easy to get sick; On the other hand, due to a combination of factors such as environmental pollution, more and more varieties of pig viruses Once the new virus is difficult to heal. "
　　21st Century Network in Jhulin Village to see street shops are mostly for feed mills and veterinary shop quite a lot of quantity.
　　For media coverage of the "swine fever", many interviewed insisted that the dead pig is not as "swine fever", there is no epidemic. Local government officials said swine fever, blue ear disease, foot-and-mouth disease is a the three compulsory vaccination vaccine, therefore swine fever that does not hold.
　　According to the test results, the Shanghai the some dead pigs who found porcine circovirus.

Here's a couple of sources that indicate that PCV2 is capable of causing serious disease on its own, and also in adults.

Association of Myocarditis with High Viral Load of Porcine Circovirus Type 2 in Several Tissues in Cases of Fetal Death and High Mortality in Piglets. A Case Study J VET Diagn Invest July 2007 19: 368-375, doi:10.1177/104063870701900405


Abstract

During a period of 1.5 months, a newly established pig herd experienced a high number of mummifications and stillbirths, a high neonatal mortality rate, and many piglets with congenital tremors or hind leg ataxia. After clinical and histological investigations, the submitted animals were divided into 4 groups: mummified or stillborn (N = 6), live born with myocarditis (N = 5) (average age 22.8 days), live born without myocarditis (N = 14) (average age 20.0 days), and control animals from a different herd (N = 5) (newborn). Statistically significant differences were observed in the mean porcine circovirus 2 (PCV2) load among the 4 groups in the liver (P < 0.0001). The presence of PCV2 antigen within the myocardial lesions was confirmed by immunohistochemistry. A high load of PCV2 DNA was observed in myocardium, liver, and spleen from mummified or stillborn piglets (>1 ? 107 copies per 500 ng DNA), lower in piglets with myocarditis (>1 ? 105 copies per 500 ng DNA), and even further lower in pigs without myocarditis (<1 ? 105 copies per 500 ng DNA), whereas no PCV2 DNA was detected in the control animals. Myocardium, liver, and spleen were well suited for routine testing of fetuses and young piglets by quantitative real-time polymerase chain reaction. Neither porcine parvovirus nor encepaholomyocarditis virus was detected. These results indicate that the PCV2 infection might have been of etiological importance for the fetal deaths and piglet mortality observed in this herd.

Porcine dermatitis and nephropathy syndrome (PDNS) is another disease associated with PCV2 (Rosell et al, 2000). It can be observed in nursery, growing and even adult pigs (Drolet et al, 1999). Hemorrhagic, necrotizing skin lesions on the caudal part of the pig?s body are the most striking feature of PDNS in affected pigs (Thibualt et al, 1998). Pigs can also develop anorexia, depression, stiff gait and mild fever (Drolet et al, 1999). Cause of death in affected animals is acute kidney failure (Segal?s et al, 1998).

This could be an evolving pathogen and perhaps a feed contaminant that damages pig kidneys could have played a part in a high mortality event.

Re: China - A report of 15,000 dead pigs found floating in Shanghai river

According to Chinese authorities, some of the dead pigs tested antibody-positive for circoviruses, or PCV-2, and samples of the virus were isolated from Huangpu River. The implication was that the Shanghai pigs died of PCV-2, a type of virus that is harmless to human beings, as well as birds. Photographs of the carcasses reveal that the animals were large adult hogs, but PCV-2 does not kill adult pigs -- it is lethal to fetuses and newborn piglets.

That isn't true about PCV-2 never killing adult pigs.

Some links here about how PCV-2 is a rapidly evolving pig pathogen and a clinical presentation causing lethal kidney failure in adult pigs:
http://www.flutrackers.com/forum/sho...5&postcount=22

Here is another study about a lethal neurological presentation in slaughter-weight pigs:

Unusual central nervous system lesions in slaughter-weight pigs with porcine circovirus type 2 systemic infection
[snip]
Pigs were sent to slaughter between weeks 12 and 17 after placement (150 to 185 d of age). Most of the mortality occurred during week 16 (178 d of age); only 346 pigs remained in the barn: 18 (2%) pigs died during that week, with the previously described clinical signs. By the end of the finishing period, 72 (8.1%) pigs had died, 42 (4.7%) of which were recorded as sudden death, locomotor/nervous problem, or PDNS between weeks 12 and 17. Thirteen (1.4%) were euthanized for unspecified reasons...

So now there are at least two clinical presentations of PCV-2 in recent years that have killed 'adult' pigs. I'm not saying PCV-2 was the cause of death of the pigs in China, but it cannot be ruled out because the bloated carcasses looked like slaughter weight pigs.

Abstract
Background

Porcine circovirus type 2 (PCV2), the causative agent of postweaning multisystemic wasting syndrome (PMWS), is a serious economic problem for the swine industry in China. In this study, we investigated the genetic variation of PCV2 in China using strains isolated from 2004-2008. Viruses were isolated from samples collected from pigs with multi-systemic lesions and clinical signs of PMWS from different regions of China, and the genomes of these viruses were sequenced. The assembled sequences were used to define the genotypes of these strains; PCR-RFLP methodology was used to distinguish isolates and capture ELISA was used to demonstrate the antigenic changes resulted from ORF2 gene mutation of the isolates.
Results

We identified 19 PCV2 isolates, including four newly emerging PCV2 mutant strains. The 19 isolates were designated into three genotypes (PCV2a, PCV2b and PCV2d). PCV2d represented a novel genotype and a shift from PCV2a to PCV2b as the predominant genotype in China was identified. This is the first report of 1766 nt PCV2 harboring a base deletion at other new different positions. Amino acid sequence analysis identified two novel ORF2 mutations (resulting in ORF2 sequences 705 and 708 nt in length) in three deletion strains (1766 nt) and one strain with a genome 1767 nt in length. Finding of two amino acids elongation of the ORF2-encoded Cap protein is firstly observed among PCV2 strains all over the world. The isolates were distinguished into different genotypes by PCR-RFLP methodology and antigenic changes were present in Cap protein of mutation isolates by capture ELISA.
Conclusions

The results of this study provide evidence that PCV2 is undergoing constant genetic variation and that the predominant strain in China as well as the antigenic situation has changed in recent years. Furthermore, the PCR-RFLP method presented here may be useful for the differential identification of PCV2 strains in future studies.

Changsha govt says dead pigs carried no trace of infectious diseases

Global Times | 2013-4-9 0:18:08
By Zhang Zihan

The government of Changsha, Hunan Province, said Monday that no trace of infectious diseases had been discovered in the carcasses of pigs found in the Liuyang river that passes through the city, calling on residents to keep calm.

More than 70 dead pigs were found drifting in the water under the Liuyang river bridge in the city Saturday, followed by another 20 spotted on Monday morning, Liang Feicai, a press officer for the city government, confirmed to the Global Times Monday.

"Most were already decayed and the city authorities have removed, sterilized and buried all of them," said Liang. He added that the pigs' cause of death remains unknown as the local health department has examined samples but so far has not discovered traces of infectious diseases.

"Most had no ear tags so we cannot trace them, but it's highly probable that these pigs came from upstream areas. They were probably already dead before being thrown into the water," said Liang.

"Huangpu dead pig" incident Zhejiang salvage dead animals 88000

Source: China News Published :2013 -07-25 18:17


July 25, reporters from the second session of Zhejiang Province, the fourth meeting of the Standing Committee has learned that over the past three months, the Zhejiang river salvage and harmless treatment of dead animals 88,000 bulls (feathers, only ).Standing Committee members have said that after the events of Huangpu dead pigs are still so many dead animals, source control aspects worthy of reflection.


According to the Vice Governor of Zhejiang Xiong Jianping introduced in the carry out the "1000 Model Village, 10000 Village rectification", the rural environment, "five remediation an increase," "contiguous rural environment improvement" and other works based on, since last year, Zhejiang have been deployed carry out the "three edges" and "double clear" operation.
