Brucellosis and listeria cases linked to raw milk in Delaware

The Delaware Division of Public Health (DPH) has identified simultaneous cases of brucellosis in a 58 year old female New Castle County resident and listeriosis in a 44 year old male in Sussex County. These illnesses are both bacterial infections which primarily affect those consuming or coming into contact with contaminated animals or animal products, most commonly the consumption of raw food or dairy products. In both instances, these patients had consumed raw dairy products prior to becoming ill, and the individual with listeria had also been handling raw poultry products. No other risk factors have been identified.

The brucella case was hospitalized and discharged. The listeria case is still admitted but stable.

DPH statewide inspections of retail food establishments are in place to protect consumers from purchasing or consuming raw dairy products, but unlawful distribution may still occur.
