Step 1: Issue a press release that is reported on but doesn't give enough detail for consumers to take any meaningful action.
Step 2: Don't put the press release in the "Media releases" section of your web site, and put no information about the issue anywhere on your web site, least of all the home page. This works even better when the company involved doesn't seem to have a web site.
Step 3: Wash your hands of the problem, after all you did warn everyone! Too bad if nobody can work out exactly what products have been recalled.
I suppose our recently-installed bathroom light/fan/heater is okay since it is branded "IXL" which isn't in the ABC article's list. Though I've got no confidence about anything being accurate there.
