New York-based BrightFarms has issued a recall for various packaged greens due to the potential presence of metal.

BrightFarms recalled a number of products “after discovering that certain produce may have been compromised” because of construction at its Elkwood, Va., greenhouse, according to a notice on the U.S. Food and Drug Administration website.

The recall includes clamshells of baby romaine, mixed greens, arugula, baby kale, spring mix, spinach blend and baby spinach, with best-by dates May 22-26. Also included in the recall are the company’s basil, Thai basil and lemon basil with best-by dates May 18-23.

Those products are sold at Giant Carlisle, Giant Landover, Martin’s Food Markets and Peapod in West Virginia, Maryland, Pennsylvania, Virginia, Delaware and Washington, D.C., and may also have been distributed through the Capital Area Food Bank.

Retailers have been told to remove any recalled items from shelves.

Products grown at the company’s other greenhouses are not affected by the recall.
