The Smoking Bones BBQ restaurant serves an excellent spinach salad as an accompaniment to its popular chicken and rib dishes. Michelle Brennan, the restaurant's manager, purchases all of her produce, including fresh spinach used in the salads, from a local vendor.

Unfortunately, one of Ms$.$ Brennan's guests becomes ill after eating at her restaurant. The source of the illness is traced directly to the fresh spinach used in the restaurant's salads. In fact, upon further investigation, it is determined that the spinach, when delivered to the restaurant's produce vendor, was already infected with E$.$ coli bacteria that matched a strain identified in cattle manure used to fertilize the spinach field.

According to the UCC, a seller has a responsibility not to sell defective products. Who, in this example, is the seller?
