The US Centers for Disease Control and Prevention (CDC) is currently investigating a multistate outbreak of Salmonella Stanley infection, which is believed to be associated with consumption of raw cashew cheese produced by The Cultured Kitchen in West Sacramento, California.
The outbreak has affected at least 14 people in California, Nevada and Wyoming since 13 November 2013. Three cases have been hospitalised, but no deaths have been reported. Epidemiological and traceback investigations have identified the consumption of raw cashew cheese produced by The Cultured Kitchen as the most likely source of the outbreak.
Cashew cheese is a non-dairy product made from raw cashews with other added ingredients. On 31 December the manufacturer voluntarily recalled all six varieties of the product with use by dates up to and including 19 April. The recalled cashew cheese was distributed through natural food stores and farmer’s markets in California and Nevada
The outbreak strain of Salmonella Stanley is unusual and has only been reported 20 times before in the USA. According to an FDA press release, it is much more common in Southeast Asia, from where The Cultured Kitchen sources its supplies of cashew nuts.
