Fox News Senior Correspondent Jonathan Sery talks to medical and agricultural experts about testing for avian flu and dairy cows.
The USDA Animal and Plant Health Inspection Service (APHIS) recently confirmed that a fatal avian influenza genotype has been found in Nevada dairy cows that can kill herds around the country.
According to a statement, on Friday, the Affis National Veterinary Services Institute (NVSL) discovered highly pathogenic avian influenza (HPAI) genotype D1.1 in dairy cows.
The confirmation comes from a state tracing and investigation following the initial detection of silotests based on the USDA's National Milk Test Strategy in Nevada, officials said.

“USDA APHIS continues to work with the Nevada Department of Agriculture by gathering additional farm surveys, testing and additional epidemiological information to better understand this detection and limit the spread of further diseases. “We will,” the statement read.
This is the first detection of viral genotypes in dairy cows. All previous detections of dairy cows are of different genotype b3.13.

Genotype D1.1 represents the major genotype of North American flyways over autumn and winter, and has been identified in wild birds, mammals and in domestic chicken in runoff, according to the Affith.
Due to Fox Business previously reported, eggs are becoming increasingly difficult to find and are becoming more and more expensive nationwide.
This detection does not change USDA's HPAI eradication strategy and is “proof of the strength of the domestic milk testing strategy.” According to officials.

To share import information with the scientific community, Affis will publish a technical brief about the findings of its website and post sequence data for GenBank next week.
