Animal Welfare Act

Tens of thousands of animal welfare documents were removed from the USDA's website at the beginning of February, and although some have been reposted, local and national animal welfare advocates continue to press the USDA to restore them.

The USDA maintains the records were removed in an ongoing effort to "balance the need for transparency with rules protecting individual privacy." 

The Animal Welfare Act oversees research labs, zoos, circuses and animal breeders: almost eight thousand facilities.
