Enoki mushrooms have been recalled. The enoki mushrooms sold between January 13th and January 30th, 2009 have been recalled because of a possible Listeria contamination. The company says that the mushrooms were packaged in one-pound clear bags. These mushrooms may be contaminated with Listeria monocytogenes which can cause the sometimes fatal listeriosos.
Enoki mushrooms are considered to be gourmet mushrooms and are expensive simply because they grow at the snow line in the mountains. Typically the caps of the mushrooms are as wide as the stems are long. Listeriosis can be acquired by eating uncooked foods including meats, cheeses or vegetables. These foods can be contaminated by ill animals or when food is not completely cooked. Full cooking is the best defense against this problem.
In Illinois we have a period of time in the spring which allows for the picking of mushrooms, which by the way is a fungi neither plant nor animal. The problem with we amateur mushroom hunters is that we mess up sometimes trying to discern between a good mushroom and one that is dangerous.
