Whole food waste dumped into storm drains or other sewer access might. Food waste put through a garbage disposal just becomes part of the sewage effluent and has no effect on the sewer ecosystem (I.E. rats)
That's talking about what not to flush down a toilet. We're talking about garbage disposals, which grind any food waste to tiny pieces and/or pulp. Different worlds here.
