Imperfect but forgiven
My comment about the way tilapia is raised is clearly written on the back of the package. The Chinese throw all sorts of unclean things into their ponds, and I can't imagine that any fish raised there could be very healthy.
My package doesn't have any yucky details. It just says stuff like responsibly farmed, sourced, etc. Maybe this box of tilapia wasn't raised on chicken excrement.
