The Linn and Johnson County Public Health Departments are warning the public not to eat guacamole, salsa and uncooked tamales prepared by La Reyna Supermarket & Taqueria of Iowa City before July 19.  The products were sold at farmers’ markets in Linn, Johnson and Dubuque counties and may be contaminated with salmonella. The departments say any guacamole, salsa and uncooked tamales should be thrown away and not eaten.

The salmonella investigation was initiated by Linn County Public Health officials and illnesses were traced to products produced by the restaurant in Johnson County.
