Plaintiff failed to establish a causal connection between her internal injuries and the ingestion of food from defendants' restaurant ( see Russac v. Crest Hollow Country Club, 252 AD2d 548; Valenti v. Great Atl. Pac. Tea Co., 207 AD2d 340). A jury must reach its verdict based on logical inferences from the evidence, rather than on speculation ( Tardella v. RJR Nabisco, 178 AD2d 737, 739). Plaintiff has offered no medical explanation that might reduce the possibility that the foreign object came from an alternative source.
