Simmons processes tuna and sells it to Odar, a food distributor. Odar sells Simmons's tuna to retail grocery stores, including JRB. JRB sells the tuna to grocery shoppers. On particular batch of tuna made by Simmons was not properly refrigerated at Odar's warehouse, as a result of which it developed higher levels of harmful bacteria than intended and acceptable for human consumption. The tainted tuna was sold to JRB, which sold it to Kim. Kim served the tuna at a neighborhood potluck dinner, and several neighbors became sick.
