Red Vines is a brand of red licorice candy manufactured in Union City, California by the American Licorice Company. Red Vines Original Red twists, are also sometimes referred to as red licorice. The original Red Vines were raspberry-flavored, but in 1952, with a slight formula change, the Red Vines Original Red Twist flavor was introduced. Red Vines Red Twists appear very similar to Twizzlers candy. In August 2012 the California Department of Public Health announced a recall of one lot of Red Vines' black licorice candy due to lead contamination. Only the one-pound packages marked 'Best Before 020413' were recalled. Testing found that candy in the contaminated lot had as much as 0.33 parts per million of lead resulting in up to 13.2 micrograms of lead per serving. This was more than double the limit of 6.0 micrograms of lead per day from all dietary sources for children under 6 years old.
