A walkway for a liquid heat transfer cabinet for food products to preclude contamination of the liquid heat transfer medium so that an operator can manually load and unload the cabinet with product to be subjected to a heat transfer operation. The walkway includes a fixed channel-shaped member mounted above the floor so that the liquid level cannot enter the fixed member and a swingable channel-shaped member functioning as a cover to the fixed member and also disposable in open position to define a walkway area like the fixed member and above the liquid level. In closed position the cover member prevents liquid from entering the area of the fixed channel-shaped member.
