Exposing food manufacturers to widespread civil suits like this would surely depress domestic production of food just as opening up fabric manufacturers to fire-related civil suits (e.g. Chapman v Brown) destroyed domestic fabric production. Even if the manufacturer wins 99% of the time, the proliferation of suits like this is sufficiently costly to force production overseas. You still end up with the same (or greater) risks, but the system routes around the legal friction by reducing production in the costly legal regime.
