Here is my $0.02 worth.....
I have had the same problem with Sam's Club ribs.... so far, I have been able to rinse them, and let sit for a few minutes and it would go away... I attributed it to the blood in the pack... Am I right or wrong??? I don't know either..... btw, I usually by the spares and cut to ST. Louis style, so can't say about the BB's.....
I bought a case from Restaurant Depot and have not had the problem... so, is it just Sam's ribs???? RD has IBP and Sam's has Smithfield... The only problem for me is the nearest RD is abt 2 hrs away.... so for a 4 hr drive it isn't worth it just for a pack of ribs... so when I do go, I buy a case of ribs and a case of butts and......
I would suggest, rinse good and see if it goes away. If so, like I said, I chalk it up to blood... if it doesn't go away, I would bite the bullet, take them back, and insist that this is NOT the first time, and it will be the last and open up another pack before you leave the store... if it stinks, leave it with them, and then after opening up a bunch and still stinking, insist on a full refund and leave then with ALL the open packages.... :mrgreen:
