At Ngoc Sinh Seafoods Trading & Processing Export Enterprise, a seafood exporter on Vietnam’s southern coast, workers stand on a dirty floor sorting shrimp one hot September day. There’s trash on the floor, and flies crawl over baskets of processed shrimp stacked in an unchilled room in Ca Mau.
Elsewhere in Ca Mau, Nguyen Van Hoang packs shrimp headed for the U.S. in dirty plastic tubs. He covers them in ice made with tap water that the Vietnamese Health Ministry says should be boiled before drinking because of the risk of contamination with bacteria. Vietnam ships 100 million pounds of shrimp a year to the U.S. That’s almost 8 percent of the shrimp Americans eat. Using ice made from tap water in Vietnam is dangerous because it can spread bacteria to the shrimp, microbiologist Mansour Samadpour says, Bloomberg Markets magazine reports in its November issue. “Those conditions -- ice made from dirty water, animals near the farms, pigs -- are unacceptable,” says Samadpour, whose company, IEH Laboratories & Consulting Group, specializes in testing water for shellfish farming. Ngoc Sinh has been certified as safe by Geneva-based food auditor SGS SA, says Nguyen Trung Thanh, the company’s general director. No Record“We are trying to meet international standards,” Thanh says. SGS spokeswoman Jennifer Buckley says her company has no record of auditing Ngoc Sinh. At Chen Qiang’s tilapia farm in Yangjiang city in China’s Guangdong province, which borders Hong Kong, Chen feeds fish partly with feces from hundreds of pigs and geese. That practice is dangerous for American consumers, says Michael Doyle, director of the University of Georgia’s Center for Food Safety. “The manure the Chinese use to feed fish is frequently contaminated with microbes like salmonella,” says Doyle, who has studied foodborne diseases in China. On a sweltering, overcast day in August, the smell of excrement is overpowering. After seeing dead fish on the surface, Chen, 45, wades barefoot into his murky pond to open a pipe that adds fresh water from a nearby canal. Exporters buy his fish to sell to U.S. companies. Yang Shuiquan, chairman of a government-sponsored tilapia aquaculture association in Lianjiang, 200 kilometers from Yangjiang, says he discourages using feces as food because it contaminates water and makes fish more susceptible to diseases. He says a growing number of Guangdong farmers adopt that practice anyway because of fierce competition. “Many farmers have switched to feces and have stopped using commercial feed,” he says.

There's a method of farming in Asia called aquaculture which involves fish ponds being fed by pigs and/or poultry housed above them. Feces drops down to the pond below, and that water is then pumped back up to the animals/poultry above. As if that wasn't bad enough, the ponds are open so migratory waterfowl can land in them, potentially infecting the water with flu viruses they carry in their gut.

"Waste not, want not"
They didn't waste it, BUT I don't want it Actually, nature recycles things - but is the aqua-cycle (mentioned above) too short* to kill the pathogens as it goes from one stage to another? * too short = either too few steps or too short a time. Note: good composting of human waste can kill the pathogens either by it being hot enough [62C/144F for 1 hour, or 50C/122F for 1 day, or 46C/115F for 1 week, or 43C/109F for 1 month), or by it being composted long enough (over 1 year) |

The worry is the opportunity it affords for re-assortment as avian and swine strains continually cycle through the system, with wild viruses thrown into the mix every time an infected migratory waterfowl defecates in the pond. Between this, China's wet markets, and poor biosecurity at intensively raised poultry and pig farms, it's a wonder we haven't unleashed a modern day major flu pandemic on the world yet. Yet. |

Spot on Jacksdad,that's what I was thinking,and I couldn't see any pathogens being killed off,by going through the gut of a prawn,I've cleaned the poo line out of many,reminds me of how the "mad cow"thing happened in the UK ,

Yep, you know the digestive tract of a prawn or shrimp isn't robust enough to kill anything. And what they didn't get a chance to digest is still in there. Poo line... |

Right you are! It is an ancient practice in China...they used to shovel manure into a pond, which would grow "infusoria" (small crustaceans, algae, rotifers etc.) and this was used to grow carp. They usually feed swine the same way, using duck/chicken feces, and feeding dead birds to the pigs. That is why we will have a killer hybrid influenza show up someday. The US is culpable...there is common feeding of poultry litter (poop) to beef cattle in parts of the USA. I know guys from companies like ConAgra who won't eat beef grown in certain areas due to this. "We dig our graves with our teeth."
