(CNN) – Tanimura and Antle is voluntarily recalling thousands of heads of romaine lettuce over possible e. Coli contamination
The recall appeared on the Food and Drug Administration website.
The grower is recalling nearly 3,400 cartons distributed in 19 states and Puerto Rico under its namesake brand.
Each case has between a dozen and two dozen heads of lettuce.
Each head is individually packaged.
The labels say they were packed on October 15 or 16.
The recall is based on a random sample collected and analyzed by Michigan health officials.
There are no reports of sickness linked to the product.
Tanimura and Antle says the recall is being done out of an abundance of caution.
The lettuce was shipped to Alaska, Oregon, California, Texas, Arkansas, Oklahoma, Indiana, Nebraska, Missouri, Tennessee, Wisconsin, New Mexico, South Carolina, Washington, North Carolina, Ohio, Virginia, Massachusetts, Illinois and Puerto Rico.
