Consumption of mung bean sprouts at Asian style restaurants in central Florida (April, 2001), southern and mid-coastal Maine (January, 2002), and Edmonton, Alberta, Canada (February, 2001) was associated with illness caused by Salmonella Enteritidis, phage type 913. Sprouts consumed in Maine were produced by the same Maine grower who received contaminated seed stock. Sprouts used by the Florida restaurants were supplied through sources in Orlando and Tampa. Mung bean seeds were supplied by a US producer. Canada linked their outbreak to the same US warehouse. Data suggested that the mung bean seeds originated in China and was brokered or supplied through the US distributor.
