A new outbreak of the H5N2 avian flu virus has struck Arkansas and Missouri poultry producers, causing massive problems for U.S. exports.

The bird flu strain, which doesn’t pose a threat to humans, is quite a big threat to chickens and turkeys and has prompted countries that import U.S. poultry to block further imports as they seek to protect flocks from the deadly virus, according to an Omaha.com report.

The strain could devastate flocks in those states, which would cause supplies to plummet and prices to skyrocket — and even if the flu isn’t as bad as some are saying, if the export restrictions remain, an oversupply of meat will cause ripple effects in the industry.

Commodity traders are closely watching the progress of the battle against the disease. If poultry prices start climbing, pork and beef markets could be impacted as well. Also, the poultry industry is a major consumer of corn and soybeans, and thus grain prices could face severe impacts from the outbreak of the bird flu.

Although some have suggested that wild birds are responsible for the outbreak of the H5N2 flu strain, which has also impacted Minnesota populations, wildlife experts are skeptical of that theory, according to a Reuters report.

An investigator with the U.S. Department of Agriculture proposed the initial theory that wild animals are the problem, saying that testing indicates that the virus is carried by waterfowl that travel a migratory route that goes from Minnesota to the gulf of Mexico, and droppings from the ducks can land on farms where the birds live.

However, some experts have noted that the disease has moved from Minnesota south to Arkansas and Missouri, which would be the opposite direction that the birds would be migrating in the spring.
