"The federal organic regulations make it very clear that all organic livestock must have access to the outdoors and that ruminants, like dairy cows, must have access to pasture," said Mark A. Kastel, senior farm policy analyst at the Cornucopia Institute, in a statement. "The vast majority of these massive, industrial-scale facilities, some managing 10,000 to 20,000 head of cattle, and upwards of 1 million laying hens, had 100 percent of their animals confined in giant buildings or feedlots."
While the Cornucopia Institute says that the collection of photos are evidence enough, the The Organic Trade Association refuted this in a statement to the Washington Post:
"We continue to have confidence in the oversight of organic operations and in the checks and balances built into the organic certification system which includes regular inspections of operations, regular accreditation audits of certifiers, and complaint investigation procedures."
While stricter regulations on livestock productions usually benefit animal welfare, the photos suggest that such rules may not always be as stringent as they seem. While not eating animal products is the only way to be sure you're not supporting factory farming, you can also look for the Animal Welfare Approved label, which requires stricter standards than most others.
