Can’t wait to chow down on those burgers and pork chops that you grilled tonight? Ponder the likelihood that your dinner may have been unfortunate enough to grow up in a factory farm. Industrial animal production, the practice of confining thousands of cows, hogs, chickens, or other animals in tightly packed facilities, has become the dominant method of meat production in the United States.

These factory farms seriously harm human health and the environment in the communities where they locate. Take, for example, the fact that the millions of gallons of manure and other waste these industrial farms produce cannot be properly managed and often spill into waterways. They emit toxic chemicals that can cause hazardous air and water pollution. People working in these animal factories or those living nearby often suffer intensely from the odors and experience a range of negative physical effects.

We’ve used USDA data to create a new map that shows the regional concentration of these concentrated animal feeding operations (CAFOs), but people thousands of miles away from these facilities are not immune to their effects. Consumers eating the dairy, egg, and meat products produced there are faced with the consequences of antibiotic and artificial hormone use and other food safety problems.

Concerned? You should be.

Do something about it. Use our new map to discover if factory farms have encroached on your state or county. And, don’t forget to vote with your almighty dollar by purchasing meat produced in a more sustainable way. Learn how with the Eat Well Guide.
