The Canadian Food Inspection Agency has issued a warning to consumers not to purchase or eat certain brands of bagged lettuce.

The ready-to-eat products may be contaminated with salmonella.

A number of brands of Fresh Express Romaine-based salads are included in a recall issued by the manufacturer, Fresh Express Incorporated.

The CFIA issued the warning after the Salinas, California-based company announced the recall.

The products have use-by dates from May 13 to May 16 and have an "S" in the product code, the CFIA said.

The use-by date is located in the upper right hand corner of the package with the product code immediately underneath.

The recalled products have been distributed in B.C., Alberta, Manitoba, Ontario and Quebec and may have been distributed nationally.

There have been no reported illnesses associated with the consumption of these products.
