China: 20 tons of pig meat sold as halal to Muslims

Serious question:

How big a deal is this for Muslims?

Is this a, 'I didn't knowingly eat pork so I'm okay' or is it a , 'my immortal soul is now in danger'

I'm sure they'll be told that they're OK because it was not their intention. That, or they should cleanse their souls with prayer and/or explosives.
