Bird flu cases are on the rise across the country as wild flocks migrate south for the winter, mingling with domestic poultry farms and backyard birds as they go. As of Nov. 7, bird flu has been confirmed in 67 flocks across the country in the last 30 days, leading to the deaths of 3.72 million birds across commercial and backyard flocks.

Migrating wild birds are spreading the virus to domesticated flocks, increasing the risk of eventually seeing a human outbreak. Scientists are troubled by the muted federal response.

A ccording to a press released issued by Grays Harbor County Public Health, a Grays Harbor County resident has tested preliminarily positive for avian influenza, also known as bird flu. Confirmatory testing through the Washington State Public Health Laboratories is pending.

People have been warned not to touch dead or sick birds after a case of avian flu was confirmed in Nottinghamshire. The disease was found in a wild whooper swan in Shelford, according to Nottinghamshire County Council. Wild birds which migrate to the UK can carry the disease which can lead to cases in poultry and other captive birds.

More outbreaks could mean fewer turkeys available at Christmas with risk of higher prices. Smaller birds may be produced in an effort to alleviate market uncertainties, though most big flock operators are locked into a production system dictated by the requirements of large supermarkets.

Nearly two million U.S. turkeys have died from bird flu in recent months. An agricultural economist explains what ongoing outbreaks could mean for Thanksgiving meals
