The cactus was sold at two locations in the East Bay -- at La Superior Supermercado in Pittsburg and at Mercado del Valle in Concord.
The product, imported from Mexico, was sold in bulk bins without any specific labeling or branding.
The state Department of Public Health said Sunday that a recent inspection of the cactus found traces of Monocrotophos, a pesticide that has been barred from use in the United States since 1989. Consumption of the pesticide can lead to neurotoxicity and permanent nerve damage.
The department is urging anyone who bought the contaminated product at the following stores between Feb. 6 and 12 to return it or get rid of it.
