Here's another link you might explore when she starts talking about gross stuff in meat:

"The Food Defect Action Levels"
It's the levels of various defects in food allowed by the FDA as "unavoidable" or present no health hazard for humans. But there are some pretty gross things here. For example, if someone likes Apple Butter, here's the listing:
APPLE BUTTER Mold
(AOAC 975.51) Average of mold count is 12% or more
Rodent filth
(AOAC 945.76) Average of 4 or more rodent hairs per 100 grams of apple butter
Insects
(AOAC 945.76) Average of 5 or more whole or equivalent insects (not counting mites, aphids, thrips, or scale insects) per 100 grams of apple butter
DEFECT SOURCE: Mold - post harvest infection. Rodent hair - post harvest and/or processing contamination with animal hair. Whole or equivalent insects - preharvest, and/or post harvest and/or processing insect infestation,
SIGNIFICANCE: Aesthetic
I always ask if they eat insects, can they actually call themselves vegetarians?
