Hog deaths, manure flooding from Florence seen surpassing 2016 hurricane

CHICAGO, Sept 18 (Reuters) - More than 2,800 hogs on farms in North Carolina are estimated to have died in flooding from Hurricane Florence, exceeding the number killed in the state's last major hurricane two years ago, the state's agriculture commissioner said on Tuesday.

"I'm just assuming, based on the depth of the water that we had in North Carolina and the amount of rainfall, that we probably will exceed what we had in Matthew," Commissioner Steve Troxler said in an interview after flying over flooded areas.

North Carolina has 8.9 million swine, representing 12 percent of the U.S. herd, according to the U.S. Agriculture Department. Raised in barns, they can become trapped and drown in floods.

Poultry losses will also likely exceed the 1.8 million birds that died from Hurricane Matthew, Troxler said.

"There are going to be some pretty good losses on the poultry side judging from the flooded houses that we saw," he said.

North Carolina is the country's No. 2 swine-producing state, its leading producer of tobacco and a major poultry producer, making agriculture its principle industry, valued at $87 billion.

Hurricane Florence, which came ashore last Friday with torrential rains, has caused more outdoor hog manure pits to collapse and overflow in North Carolina than Hurricane Matthew did in 2016, according to state data, stoking concern about possible water contamination.

The deaths of 26 people in North Carolina and six in South Carolina have been attributed to the storm.

High winds and flooding damaged two chicken farms that supply Tyson Foods Inc, the biggest U.S. meat processor, spokesman Worth Sparkman said. He said operations were minimally damaged, and the company was looking to relocate chickens that survived to other farms.

The world's largest hog slaughterhouse in Tar Heel, operated by WH Group Ltd's Smithfield Foods Inc remained closed on Tuesday but would likely be open on Wednesday, an employee said. Smithfield did not respond to a request for comment.

North Carolina's Department of Environmental Quality said on Tuesday that the walls of four pits holding hog waste, known as lagoons, had given way because of the storm, thirteen pits had overflowed due to rain, and nine were inundated by floodwaters.

Hurricane Matthew caused a partial structural failure at one lagoon, while none overflowed from rain and 14 were inundated by floodwaters, according to the industry group NC Pork Council.

More lagoons were at risk of overflowing in the days ahead, state data showed, including 30 that are filled to the brim with waste and water, and another 25 with zero to three inches of space to spare.

There are more than 3,300 lagoons in North Carolina, said Andy Curliss, chief executive for the NC Pork Council.

Hog producers, including Smithfield, lowered the levels of waste in lagoons before the storm, but up to 36 inches (91 cm) of rain overwhelmed some farms.

Matt Wellington, antibiotics program director of U.S. PIRG, a federation of public interest groups, said the release of waste from lagoons could spread antibiotic-resistant bacteria. Farmers raise hogs with antibiotics, which can be found in their waste, he said.

Sampling waterways in eastern North Carolina after Hurricane Matthew showed a temporary increase in concentrations of some bacteria and pollutants in spots, according to a 2017 report from the state's Department of Environmental Quality.
