The Centers for Disease Control and Prevention has now documented 892 cases of Salmonella Oranienburg infection involving thirty-eight states and Puerto Rico.  The case number extends to October 25th with more case reports anticipated.

Onions imported from Mexico and distributed by ProSource Produce LLC were responsible for the outbreak. Product was distributed to a range of wholesalers an suppliers who repacked under brand names for supermarkets and food service providers.

 Since onions have a long shelf life, contaminated product is still in homes and may result in additional exposure of consumers.  This outbreak may well exceed 1,000 diagnosed cases, but the actual number of those infected may be five or ten-fold greater since not all affected consumers seek medical attention and many cases are treated symptomatically without laboratory investigations.
