No, if you have FBA, once your item enters their system, it's their item. If it's seized by the FBI, AMZ will pay you fair market price for your item they've lost the possession of, or will replace it with a likewise item.

I mean, if they had any actual idea/proof that you're the one who supplied them with the counterfeit, they'd not put it into their space in the first place; once it's on the shelves, it's all shared property, and sellers don't own any individual stock.
