What is the test for establishing a breach of warranty on a bottle of Seven Up?

To establish a breach of warranty it was incumbent upon plaintiff to prove by a preponderance of the evidence that the Seven Up was purchased from defendant retailer and bottled by defendant bottling company; that it was unfit for consumption when sold to plaintiff; and that as a result of drinking the Seven Up plaintiff sustained injuries. Vaccarezza v. Sanguinetti, supra, 71 Cal.App.2d at pages 690-691, 163 P.2d at page 473. If a foreign substance found its way into the bottle after plaintiff opened it, defendant would not have breached any warranty and plaintiff would not be able to recover.
