US-based company BrightFarms is recalling salad products sold in Giant Food stores due to possible metal contamination.

As confirmed by the US Food and Drug Administration (FDA), the packaged products are possibly contaminated with metal as a result of construction at BrightFarms’ greenhouse farm in Elkwood, Virginia.

The products that are subject to recall include various mixed salad packages and basil products.

Packaged in clear and plastic clamshells, the products feature best by dates of 22 May, 23 May, 24 May, 25 May and 26 May.

"The recall has been initiated after BrightFarms discovered that certain produce may have been compromised."

The products are sold at the Giant Landover, Giant Carlisle, Peapod and Martin’s Food Markets in Pennsylvania, Maryland, Virginia, Delaware, West Virginia and Washington DC.

The recalled products may also have been distributed through the Capital Area Food Bank.

The affected basil products feature best by dates of 18 May, 19 May, 20 May, 21 May, 22 May and 23 May.

BrightFarms products from greenhouses in other regions are not affected by the recall.

The recall has been initiated after BrightFarms discovered that certain produce may have been compromised.

Retailers carrying the affected products have been instructed to remove them from store shelves.

Consumers who have bought the affected products have been urged to discard them or return the products to their place of purchase for a full refund.
