FAQ

  • CAFOs (Concentrated Animal Feeding Operations), commonly referred to as “factory farms,” are intensive animal agriculture operations in which large numbers of animals are confined and/or a large amount of waste is created. The Environmental Protection Agency (EPA) defined this term to classify farms that pose a risk of water pollution.

    A facility that confines more than 125,000 chickens raised for meat, more than 82,000 egg-laying hens, or more than 700 mature dairy cows is considered a large CAFO. A medium CAFO must contain the medium size range of animals listed by the EPA and also directly discharge animal waste into surface water, which no farms in Sonoma County are permitted to do. To learn more, read the EPA’s definition of CAFOs or check out their chart summarizing the CAFO definition.

  • There are an estimated 21 CAFOs, also called factory farms, in Sonoma County. They effectively market themselves as small-scale, family farms, but the reality is that these 21 facilities all meet the federal definition of a large CAFO and together confine around 3 million animals. Investigations into many of these facilities have found rampant animal cruelty. Learn more about factory farms in Sonoma County, or read What are CAFOs?.

  • CAFOs are bad for animals, the environment, local farmers, and public health. Despite bucolic imagery on their marketing, investigations into CAFOs in Sonoma County have found rampant animal abuse, including animals left to slowly die without food or water. Emissions from industrial animal agricultural operations are a significant cause of climate change, with livestock contributing 12 percent of all greenhouse gas emissions, which worsens the drought and wildfires in Sonoma County. As factory farming corporations have entered rural areas of Sonoma County with giant, windowless sheds, local farmers have been put out of business and residents have lost the benefits of quality food and a truly local economy. Workers at CAFOs face health risks due to exposure to harmful substances and antibiotic-resistant bacteria, as well as high rates of respiratory injuries, musculoskeletal injuries, and anxiety and depression. And finally, given that three out of four emerging infectious diseases are zoonotic, CAFOs pose a serious risk to public health. Institutions like the Centers for Disease Control and Prevention (CDC) and the American Public Health Association (APHA) are calling for action to protect against the harms of CAFOs. For all these reasons, the factory farming industry is one of the most destructive and harmful industries on the planet - an industry that is not in line with the values of Sonoma County residents.

  • The majority of the estimated 21 CAFOs in Sonoma County are operated by or supply to massive agricultural companies. For example, seven of the CAFOs are operated by a single company, Sunrise Farms LLC, which sells eggs to Costco, Safeway, Walmart and other large retail chains. Perdue Farms Inc, the fourth largest poultry company in the United States, also operates multiple CAFOs in Sonoma County. Three of the large dairy CAFOs in Sonoma County supply to a corporation that has local roots - Clover - but is now majority owned by a Colombian agricultural company, Alpina Productos Alimenticios, with annual sales over $700 million. Clover also supplies from multiple CAFOs in the Central Valley.

  • Yes. While avian flu is often carried by wild birds, CAFOs are a perfect location for avian flu and other viruses such as swine flu to rapidly spread. In CAFOs, massive numbers of animals (sometimes hundreds of thousands) are confined in crowded, unsanitary conditions. This allows viruses to easily spread from one animal to another. These conditions also increase the chances for viruses to mutate, causing new strains to emerge which could be even more contagious or deadly and could have the potential to infect humans. Because workers at CAFOs are often in close proximity to these animals, they are at higher risk of becoming infected and could carry the viruses out to the broader population.

    In the past few years, viruses such as avian flu have wreaked havoc across the country, including in Sonoma County. Outbreaks have caused massive economic losses, unstable food prices, and extreme suffering, as animals who are potentially infected are “depopulated” with cruel methods such as “ventilation shutdown”, where airflow is turned off in the barns, heat and steam is pumped in, and animals are left to die of heatstroke over the course of hours. In order to prevent the next pandemic and protect workers, animals, and food security, it’s imperative that we phase out CAFOs.

  • Regulatory agencies have failed to protect animals, the environment, and public health. They typically only give minor penalties, if any at all, when powerful factory farms pollute communities or spread disease. Whistleblowers have documented criminal animal abuse and dangerous, unhygienic conditions in Sonoma County CAFOs on dozens of occasions. They have reported this to local and state authorities, but no action has been taken.


    The legislature has shown time and time again that they are unwilling to confront this powerful industry, but with a ballot measure, citizens can directly vote to change the law without any way for corrupt politicians or lobbyists to get in the way.
