Federal regulators have issued a recall for approximately 5 million swimming pools due to a significant safety hazard. A strap design on the pool's exterior can inadvertently create a foothold, allowing unsupervised children to climb into the pool without a ladder. This defect has been linked to the tragic drowning deaths of nine children. Consumers are urged to immediately stop using the affected pools and contact the manufacturer for a refund or replacement. The recall aims to prevent further child fatalities and injuries associated with this design flaw.
