The Indiana outbreak on Jan. 15 caused around 450,000 birds to be euthanized and has caused the state to test birds up to 20 km away out of concern. Currently, there are no outbreaks of the high pathogenic strain (HPAI), but the low pathogenic strain (LPAI) is still common, despite Indiana culling even healthy birds as a preventative measure. In the coming months, biosecurity will be key in preventing farmers from Eastern Oklahoma and other areas from having an outbreak and should become a priority.
According to Dr. Josh Payne, OSU Extension’s poultry waste management specialist, contaminated food recently brought in from feed stores is a major source of contamination. Farmers may take care of their birds and then go into a feed store without properly decontaminating themselves or their equipment. If they have infected birds and handle the food or bring contaminated insects near it accidentally, the food can become contaminated and infect the birds of farmers who buy it.
Another major source of contamination is the farmers’ not wearing protective equipment such as masks, special boots, and gloves and not showering and changing clothes after work. Also, they are encouraged to wash their trucks if they have penetrated the inner perimeter of the farm where their birds are located.
Unfortunately, signals from the Deptartment of Agriculture have been mixed with regards to the minimum biosecurity measures that need to be taken. Due to this and the fact that instructions often seem more aimed at university-level agricultural specialists due to the language used, many farmers ignore the guidelines. Rewriting the guidelines for farmers who have a high-school education or less and prioritizing biosecurity requirements according to level of risk will help keep Oklahoma’s farms free from HPAI.
