At our last contest my honey injected the brisket's with a combination of FAB B and Apple Juice. She has done this before without incident but this time we had dark blotches and needle marks in the meat. Vinny (MillitantSquatter) saw it first hand. She thought she injected with the grain but maybe not. Could anyone help shed some light on what happened and what we could do to prevent this. The meat was very tasty but very underdone which is an easy problem to address, but those blotches prevented us from getting any higher than an 8 in presentation. As a matter of fact we got 8's across the board except for one 7. Thank you in advance for your help.
