When I buy ground turkey from Publix, under the ground turkey in the package there is a packet of something pinkish colored than isn't mentioned on the label, what is it? Is it maybe something from the turkey used for flavoring a broth or something?
Where I live most prepackaged meats come with a kind of fluids sponge or mat.
Those can be part of the packaging, can be clearly recognizable mats between the meat and the packaging, or it can be a bag shaped package which looks like it could contain something edible.
As it is something made to contain the liquids drained out of the meat and hold it, I do not think you should use it or anything coming out of it, as you can not know what they put in to hold the liquids. (Although it should be food safe as it is in contact with the meat.)
I see that @Tetsujin in a comment calls it a meat diaper, which seems to fit the bag and mat types.
