Case Count Update

Through a collaborative investigation with the Public Health Agency of CanadaExternal

(PHAC), a total of five ill persons infected with a strain of Salmonella Hartford matching an outbreak strain in Canada have been identified through PulseNet in five U.S. states. This strain of Salmonella Hartford has never been seen before in PulseNet. Initial interviews with ill persons suggested a link to the ongoing Salmonella Newport outbreak investigation in the United States. These illnesses have been combined with the existing Salmonella Newport infections previously identified as part of this investigation.

As of June 2, 2014, a total of 17 ill persons infected with the outbreak strains of Salmonella Newport (12 persons) or Salmonella Hartford (5 persons) have been reported from 10 states. The number of ill persons identified in each state is as follows: Arizona (1), California (2), Connecticut (2), Ohio (1), Florida (1), Massachusetts (1), Michigan (1), New York (4), Utah (1), and Wisconsin (3).

Among persons for whom information is available, dates that illnesses began range from January 21, 2014 to May 5, 2014. Ill persons range in age from 4 years to 81 years, with a median age of 51 years. Sixty-five percent of ill persons are female. Among 13 ill persons with available information, two (15%) report being hospitalized. No deaths have been reported.

Illnesses that occurred after May 16, 2014 might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 4 weeks. The recalled products containing organic sprouted chia powder have a long shelf-life and may still be in people’s homes, and illnesses may continue to be reported. Please see the Timeline for Reporting Cases of Salmonella Infection for more details.

Investigation Update

Epidemiologic and traceback findings have linked this outbreak of Salmonella infections to various brands of organic sprouted chia powder.

In interviews, ill persons are answering questions about foods eaten and other exposures in the week before becoming ill. To date, 12 (100%) of 12 persons interviewed reported eating chia seeds or powder, and 9 (75%) of 12 persons reported eating chia powder specifically.

The recalled products include Navitas Naturals Organic Sprouted Chia Powder, Navitas Naturals Omega Blend Sprouted Smoothie Mix, and Williams-Sonoma Omega 3 Smoothie Mixer. The recalled products are available for purchase in many retail stores and online.

On May 30, 2014, the Canadian Food Inspection Agency (CFIA) notified consumers that Advantage Health Matters and Back 2 the Garden recalledExternal

various products containing sprouted chia seed powder due to possible Salmonella contamination. These products are sold under the brand names Organic Traditions and Back 2 the Garden and are available for purchase online by consumers in the United States.

Several samples of leftover organic sprouted chia powder from ill persons homes and unopened packages from retail locations are being tested for the presence of Salmonella bacteria. Results of this testing are pending and will be released when they become available.

CDC, state, local, and Canadian public health partners are continuing laboratory surveillance through PulseNet to identify additional ill persons and to interview ill persons about foods eaten before becoming ill. The U.S. Food and Drug Administration (FDA) is continuing to work closely with CDC and other partners in this investigation.
