Commercial, pasteurized ice cream outbreaks are really quite rare – see Outbreak Database.
Yesterday, Snoqualmie Gourmet Ice Cream, Inc. issued a voluntary recall of all ice cream, gelato, custard and sorbet for all flavors and container sizes produced on or after January 1, 2014 until December 15, 2014 because these products have the potential to be contaminated with Listeria monocytogenes.
The voluntary recall was initiated based on the confirmation positive result of Listeria monocytogenes in the samples collected within the production facility and analyzed by Washington State Department of Agriculture (WSDA). However, today the Washington State Department of Health (WSDH), confirmed that at least two people – both men in their 50’s have been hospitalized in Seattle with Listeria infections linked to the recalled ice cream.
The ice cream, gelato, custard and sorbet were distributed in Arizona, Idaho, California, Oregon, and Washington may have been further distributed and sold in various retail outlets in Alaska, Colorado, Montana, Nevada, New Mexico, North Dakota, Texas, Utah, and Wyoming.
The products are labeled Snoqualmie Ice Cream, Snoqualmie Gelato, Snoqualmie Custard, Snoqualmie Sorbet or Emerald & Spruce Ice Cream or Top Pot Hand Forged Ice Cream and have a production date code located on the bottom of the container. The date codes included either end in “4”, e.g. XXX4 (pints and cups) or are listed by date: January 1, 2014 through December 15, 2014 (trays & tubs).
