It's still around BUT possibly not the same quality as of old. I purchased some to replace that at the bottom of kitchen cabinets in my mothers house which didn't survive a washing machine hose leak. The quality of the chipboard beneath its white plastic covering was poor with a very open structure.
Surely real wood with a coat of varnish is hygienic and can cope with the vigorous cleaning? The white coating on the chipbaord is likely to start coming off where the spray polish gets behind the surface at the edges and starts attacking the glue. or expanding the wheatabix chipboard.
