It's possible that someone might try to hold Trader Joe's liable for the actions of an unaffiliated reseller. I see no legal basis for considering that they would succeed in doing so - even under strict liability, demonstrating that modification of the product was the proximate cause of harm is usually a sufficient defense.

I imagine that spoilage in the hands of an unaffiliated reseller would be considered such a modification, but perhaps you're aware of some precedent that I am not?
