When I have deer processed into burger, I have them add bacon before they grind it. It adds fat...and nitrates. Ya' think?
If they add powdered meat tenderizing seasonings, you might get an alarm off the TSA's ETD machine. I suppose it depends on the ingredients and whether the seasonings get all over the outside of the box in high enough concentrations.
I've been told that if a passenger is carrying nitroglycerin or PETN to treat a heart condition, his baggage will most likely alarm.
