It's kind of disturbing that information about where our food comes from is being kept hidden from us. The same thing happens whenever there are major food recalls. The names of the companies where the contaminated food came from are rarely revealed to the public.
In this instance, a few articles say the name of the facility is being kept secret due to something called the "Livestock Information Protection Act". Googling "Livestock Information Protection Act" only returns articles about this incident. Assuming that the Livestock Information Protection Act is a real thing that actually exists, I'd be interested in learning why it exists.
