Strawberries Implicated in Massive German Norovirus Outbreak

Scientists from the Robert Koch institute reported on October 5th that frozen strawberries have been identified as the likely cause of the massive foodborne illness outbreak that has affected children and teenagers in almost 500 schools and day care centers in eastern Germany.  According to the latest figures, the outbreak has affected 11,200 children and teens.  Most of those who fell ill had relatively mild cases of vomiting and diarrhea, but 32 patients have been hospitalized.  The schools and kindergartens affected received food from a subcontractor of the catering firm Sodexo, which has said it will compensate victims.

Multistate Outbreak of Salmonella Infections Linked to Cantaloupe Declared Over

The multistate outbreak of Salmonella Typhimurium and Salmonella Newport infections linked to cantaloupe appears to be over, according to the final update published by the US Centers for Disease Control and Prevention on October 5.  In its update, CDC provided final case count numbers associated with the outbreak linked to Chamberlain Farms Produce, Inc. of Owensville, Indiana.  A total of 261 persons infected with the outbreak strains of Salmonella Typhimurium (228 persons) and Salmonella Newport (33 persons) were reported from 24 states.  Ninety-four ill persons were hospitalized, and three deaths were reported in Kentucky.  The map of confirmed cases is presented below, followed by the final epi curve showing the onset of cases in this outbreak.

Outbreak Map – Salmonella Infections Associated with Cantaloupe – Final October 4, 2012

Epi Curve – Salmonella Typhimurium and Salmonella Newport Infections Associated with Cantaloupe – October 4, 2012

On October 3, 2012, the U.S. Food and Drug Administration (FDA) issued a document that lists observations  [PDF – 2 pages] made by the FDA investigators during the inspection of Chamberlain Farms.  This inspection report details a large number of problems observed at the Chamberlain Farms packing facility including poor sanitary practices, food contact surfaces that were in poor condition and could not be adequately cleaned, standing water in the facility, and failure to remove litter and waste from the facility which could serve as an attractant and harborage for pests.  The FDA inspectors also obtained swab samples from environmental surfaces in the packing shed which confirmed the presence of Salmonella Newport and Salmonella Anatum.  Cantaloupes collected from the facility and a production field tested positive for Salmonella Typhimurium and Salmonella Newport.

Although this outbreak now appears to be over, it does serve to reinforce existing concerns about food safety practices used in fresh produce operations.  This is the second consecutive year that major multistate foodborne illness outbreaks have been associated with domestically-produced cantaloupes (refer here for information on the 2011 Listeria monocytogenes outbreak associated with cantaloupes produced by Jensen Farms in Colorado).  The produce industry must continue to strive to improve food safety practices during production, harvest and packing of fresh produce.

Peanut Butter Salmonella Bredeney Outbreak – Update

The outbreak of Salmonella Bredeney noted in this blog on September 23 has expanded considerably.  In an update posted by the US Centers for Disease Control and Prevention on October 5, this outbreak is currently associated with 35 cases of Salmonellosis in 19 states.  Although the case count has only increased by a small number since September 23, the scope of the recall of peanut products has grown dramatically.

Sunland Inc. of Portales, New Mexico was previously identified as the source of the peanut butter originally recalled by Trader Joe’s in September, and numerous additional recall notifications have subsequently occurred.  On October 4, 2012, Sunland Inc. expanded its ongoing recall  [PDF – 10 pages] to include all products made in the Sunland nut butter production facility between March 1, 2010 and September 24, 2012.  More than 200 products are now on the Sunland recall list, including some products that have been included as ingredients used to produce others.  This has resulted in a significant number of secondary recalls associated with products made using ingredients originating from the Sunland facility.  The list of recalled products has also expanded beyond peanut butter to include peanuts, tahini, almond butter, cashew butter and other products.

On October 5, 2012, the FDA announced that environmental samples taken in the Sunland Inc. nut butter production facility show the presence of Salmonella.  Further analysis by FDA to identify the type of Salmonella is pending.  FDA and CDC also have noted that testing conducted by the Washington State Department of Agriculture laboratory isolated the outbreak strain of Salmonella Bredeney from an opened jar of Trader Joe’s Valencia Creamy Peanut Butter collected from a case-patient’s home.

CDC recommends that consumers do not eat recalled peanut butter or other recalled products containing nuts and seeds and dispose of any remaining jars of product in the home or return the product to the place of purchase.  This is especially important for children under the age of 5 years, older adults, and people with weak immune systems.  CDC’s outbreak report notes that 63% of the illnesses associated with this outbreak have been children under the age of ten years.
