By opening the package of salmonella you've agreed to binding arbitration agreement in the venue of their choosing.... Sadly I'm not even that far from serious.

Yes, or absent that just limit the liability to a trivial amount, which many state governments have already been doing for years.

You don’t need to go that far. Just make it inconvenient and expensive.

Nah, there will be some binding arbitration clause hidden on that package of rice , so you can't sue or join a class action.
