These findings should be a red flag to world leaders—a warning that we must address the dangers of factory farming before it’s too late to prevent another public health crisis arising from our exploitation of animals.

Report Reveals Alarming Rise in Bird Flu, Warns Against Factory Farming’s “Indiscriminate Use” of Antibiotics

A first-of-its-kind report from the World Organization for Animal Health (WOAH) shows a staggering rise in bird flu outbreaks in mammals and that zoonotic diseases are spreading to new regions.
In its first annual State of the World’s Animal Health report, published on May 23, WOAH concludes that:
- Outbreaks of bird flu among mammals were over twice as high in 2024 as the previous year, “increasing the risk of further spread and human transmission.”
- Nearly half of animal diseases reaching “previously unaffected” regions of the world are zoonotic (able to spread to humans).
- While the use of antibiotics in animals dropped 5 percent from 2020 to 2022, one-in-five nations still use antibiotics to promote farm animal growth, which is “discouraged by WOAH.”
The reckless use of antibiotics in an attempt to prevent the spread of disease on factory farms is contributing to the global threat of treatment-resistant illnesses, linked to the deaths of over 1 million people around the world each year.
Meanwhile, as bird flu has spread through the poultry industry, more than 173 million farmed birds have died or been culled in the U.S. alone since January 2022. The pathogen’s spread to cattle and other mammals has alarmed scientists and health officials, who warn that bird flu could become transmissible between humans as it continues to evolve.
We already know that 75 percent of emerging human diseases are zoonotic, originating in animals. The bottom line is that if we continue to raise farm animals in the billions on filthy and crowded factory farms, we are putting ourselves at risk of the next zoonotic health disaster, just five years after the COVID-19 pandemic began.
Factory farms are breeding grounds for dangerous pathogens. To protect the public, the U.S. and other governments must shift funding away from factory farming and toward a safer, more sustainable plant-based food system.
