Biological Health Hazard – Hepatitis A (HAV) Outbreak (public health threat): U.S. (9 States)
October 17. 2016
Outbreak News Today
In a follow-up on the multistate hepatitis A outbreak linked to frozen strawberries used in smoothies at Tropical Smoothie Café locations prior to August 8, the Centers for Disease Control and Prevention (CDC) reported this week updated data on the outbreak.
As of October 17, 2016, 134 people with hepatitis A have been reported from nine states: Arkansas (1), California (1), Maryland (12), New York (3), North Carolina (1), Oregon (1), Virginia (107), West Virginia (7), and Wisconsin (1).
52 ill people have been hospitalized. No deaths have been reported.
Federal health officials say this; however, does not indicate an ongoing risk of acquiring hepatitis A virus infection at Tropical Smoothie Café’s, as the contaminated food product has been removed as of August 8. Symptoms of hepatitis A virus infection can take up to 50 days to appear.
Epidemiologic and traceback evidence indicate frozen strawberries imported from Egypt are the likely source of this outbreak.
On August 8, 2016, Tropical Smoothie Café reported that they removed the Egyptian frozen strawberries from their restaurants in Maryland, North Carolina, Virginia, and West Virginia and switched to another supplier. Out of an abundance of caution, Tropical Smoothie Café has since switched to another supplier for all restaurants nationwide.

The prepared foods section at Whole Foods’ Detroit [Michigan] store on Mack Avenue is linked to 2 recent cases of hepatitis A, the Detroit health department announced today, 20 Oct 2016. The department is asking anyone who ate prepared foods at the store from 6-12 Oct 2016 to speak to a doctor and seek preventative treatment.
“While it remains unclear exactly how either of these individuals contracted hepatitis A, and we know that Whole Foods Market Detroit has a comprehensive food safety protocol, we want to do our best to protect our residents and those of surrounding communities who may have been exposed,” said Dr. Abdul El-Sayed, executive director of the Detroit health department.
Hepatitis A, a contagious liver disease, can be spread when ingesting food or drink infected with the hepatitis A virus. Symptoms include fever, diarrhea, nausea, vomiting, yellow eyes and skin and dark urine, according to the city’s health department.

[According to another report (http://www.fox2detroit.com/news/local-news/212748366-story), one case was diagnosed in an employee who handles prepared food at the store and the other was a customer who ate prepared food. It is possible that the food preparer also ingested the food vehicle rather than contaminating it. The time of onset of the 2 cases can help differentiate the 2 scenarios. Either way, additional cases are likely to occur. Many cases of acute hepatitis A are asymptomatic or anicteric (not jaundice) and may not be diagnosed. Intervention early in the incubation period with HAV vaccine or immune globulin can mitigate or prevent the infection. – Mod.LL
