Sprouters Northwest Inc. is recalling six of its sprout products because Washington health officials believe the firm’s clover sprouts are connected to an outbreak of Salmonella Newport that’s sickened four people in the state and two in Oregon.

The Kent-based firm has stopped distributing the sprouts, sold in a variety of package sizes labeled “Clover Sprouts” or as mixed varieties that contain clover sprouts as an ingredient with “best by” dates of 01/16/2011 or earlier.

People shouldn’t eat any products from Sprouters Northwest that contain clover sprouts. The Washington Health Department recommends discarding them immediately or returning them to the store where they were purchased.

The Washington cases of Salmonella Newport occurred in mid-December among residents of Benton, King, Kitsap, and Grays Harbor counties. None has required hospitalization, health officials report.

The recalled sprouts were distributed to grocery stores and restaurants in Washington and other Northwest states.

The department urges markets, restaurants, and delicatessens to check their stock immediately and pull all of the recalled products. Retailers and wholesalers who have any of the recalled sprouts should separate them from other produce and contact their supplier.

People who have eaten sprouts and developed symptoms should contact their health care provider.
