Title: Highly Pathogenic Bird Flu Detected in US Poultry Flocks, Concerns Rise for Commercial Farms
In a concerning development for the agricultural industry, highly pathogenic bird flu has recently been detected in commercial poultry flocks in the United States. The outbreaks were reported at a turkey farm in South Dakota and another in Utah, according to the US Department of Agriculture.
The first confirmed case involved a flock of 47,300 turkeys in South Dakota, while the second outbreak affected a farm housing 141,800 birds in Utah’s Sanpete County. Surprisingly, these are the first reported cases among commercial flocks since April, when two turkey farms in the Dakotas were affected.
To prevent the flu from spreading, infected flocks are typically eliminated, and the farms are thoroughly decontaminated afterwards. Prior to these recent outbreaks, bird flu had only been sporadically observed in backyard flocks or wild birds. However, the concern now revolves around the potential spread of the disease by migrating birds, which can carry the virus without displaying any symptoms.
Predicting further cases, the South Dakota State Veterinarian warned that more outbreaks could occur as migration season begins. This news brings back memories of last year’s devastating outbreak, where the deaths of nearly 59 million birds across 47 states resulted in increased prices for eggs and turkey, costing the government over $660 million.
In 2015, the situation was even more severe, as the outbreak cost the government over $1 billion and led to the deaths of almost 51 million birds in 15 states. While bird flu infections in humans are rare and not considered a food safety risk, scientists remain concerned about the virus’s potential to evolve and spread more easily among people.
These latest cases are considered part of last year’s outbreak, which reached the US in February 2022 after spreading in Europe. To combat the virus’s spread, producers have implemented strict biosecurity measures. However, there is a limit to what they can do beyond what has already been implemented to protect their flocks.
The primary strategy involves preventing the introduction of wild bird droppings into poultry barns through various means, such as controlling workers’ footwear and clothing, farm equipment, mice, small birds, and dust particles.
Although Utah reported its first case of bird flu for this year, the state was significantly affected last year, with 16 turkey farms, one egg farm, and several backyard flocks experiencing outbreaks. South Dakota also suffered considerable losses, losing almost 4 million birds to bird flu. Interestingly, Iowa, the hardest-hit state with nearly 16 million bird deaths, has not recorded a case since March.
As the agricultural industry braces itself for the potential ramifications of these recent outbreaks, both producers and authorities are emphasizing the importance of thorough biosecurity protocols to mitigate the risk of further spread and protect commercial poultry flocks.
