US screwworm case alerts ranchers and boosts cattle prices

U.S. futures for feeder cattle surged Thursday as traders and ranchers were alerted to the possibility of more cases of a parasitic fly that eats warm blooded animals alive. U.S. agriculture secretary Brooke Rollins confirmed to reporters that there had been no more detections of New World Screwworm in the region around the case in La Pryor in Texas. The federal government confirmed this late on Wednesday. This case is a major blow for U.S. ranchers, who were bracing themselves for an outbreak of domestic screwworm as the pest has been moving northward through Mexico in the last year.

Rollins told a press conference that "we've received a few (reports)." "Certainly, none looked like the one that we saw yesterday in La Pryor. But we are pursuing that." Rollins had said that the U.S. Department of Agriculture thought it could contain this case, which is the first to occur in Texas since 1966. Further infestations may further reduce the size of the US. The cattle herd is now the smallest it has been in 75 years. Screwworms are parasitic fly females that lay their eggs on open wounds or mucous membranes of warm-blooded animals. Once the eggs hatch into larvae, hundreds of screwworms will use their sharp teeth to burrow through flesh and eventually kill their host.

"The New World screwworm sounds like a monster from a horror film, but it is real," said Nate Sheets. He was a Republican candidate for Texas Agriculture Commissioner. "It's an agricultural emergency."

VOLATILE CASTE PRICES

Chicago Mercantile Exchange traders initially reduced the price of futures for feeder cattle, fearing that the infestation would reduce consumer appetite for beef. Futures rallied by over 3%, quickly turning higher.

Experts said that the detection could threaten Texas' livestock industry. The estimated economic losses of up to $1.8 Billion in Texas could occur if the screwworm spreads.

Matt Wiegand is a commodity broker at FuturesOne. "Until we have a significant impact on consumer demand, the (cattle numbers) are still tight."

U.S. beef supplies have been dwindling after ranchers were forced to reduce their herds by a drought that lasted for years. Meatpackers such as JBS Cargill, and Tyson Foods are struggling to find enough animals to process in their beef plants.

The Meat Institute, representing processors, has urged USDA, after it announced that the agency had frozen animal movements in the area around the case, to allow "low-risk" livestock shipments for slaughter. The institute stated that such shipments may include animals being transported directly to slaughter from farms which are not infected.

USDA has spent millions to try and keep the pest out, and has been blocking imports of Mexican cattle for over a year. Rollins stated that U.S. ports will continue to be closed for Mexican livestock until further notice. According to Lee Haines, associate research professor of biology at the University of Notre Dame, Indiana, the infestation indicates screwworm flies have already arrived 'in the U.S.

Haines stated that "the burden falls on farmers who have to monitor animals spread across vast rangelands, which are often left unattended for days at time."
