The FDA announced that a food distributor is recalling all ReadyCare and Sysco Imperial Frozen Supplemental shakes, typically sold to long-term care facilities, over listeria concerns.

The supplemental shakes are labeled under the brands Lyons ReadyCare and Sysco Imperial and were sold to institutional customers, including hospitals and long-term care facilities, officials said.

The frozen shakes were served at hospitals and long-term care facilities, sickening 38 people and resulting in 11 deaths in 21 states, according to the FDA.
