Three people became ill after consuming Susumber berries at a private home. Susumber berries, members of the Nightshade family, were federally listed on the U.S. noxious weed list in 1995. The berries are commonly found in the tropics, and have been found to be toxic, although it is not clear what stage of growth is the most toxic. The berries were picked, cooked and frozen in Jamaica before being taken to the United States where they were served in a cod and rice dish. Two of the three cases experienced symptoms similar to botulism: slurred speech, drooping facial features, blurred vision, weakness and numbness. The third case consumed a smaller amount of Susumber berries compared to the other two and experienced diarrhea without neurological affects. Although the toxicity of Susumber berries is not well known, chaconine poisoning was suspected based on clinical symptoms. The contributing factor in this investigation was found to be a toxic substance naturally occurring in the Susumber berries.
