I’d ask you for a source on that. Preferably multiple reliable sources. I’ve been periodically checking for several years and haven’t been able to find a reliable confirmation of where the image is from and what it depicts. I have however seen other images of pink slime, and mechanically separated chicken that do not resemble this substance, read accounts from meat packers, as well as from people who attempted to track down the images source. Its been suggested its everything from marshmallow, to some sort of gum material, to a construction product. At no point have I seen a good, confirmable claim that its origins and content had been pin pointed. Even this Huffington Post article:
Notes the total lack of source, and attempts to tie the image (which they removed) to confirmed images of the substance. You’ll notice the major similarity is in color. In other regards the substance in the viral image does not resemble the confirmed images in the least. And if the Huffington Post, bastion of journalistic integrity and standards is can’t justify backing the image then there really must be a problem with it.
So basically we seem to have no confirmable info on the image itself. That’s what makes it a functional hoax. An unpleasant photo of who knows what, present as a handful of things we don’t like to confirm why we don’t like them. The image is often presented as what ever we’re claiming it is this week despite the wide spread knowledge that the only thing we know about it is that it likely doesn’t depict what it’s claimed to.
