Germs are everywhere

This is not helpful:

A TV ad for Dettol has been banned for making the misleading claim that a chopping board contains 50 times more bacteria than a toilet seat.
...
Reckitt Benckiser also pointed out that the study, and additional evidence, had been presented to the Broadcast Advertising Clearance Centre, which had approved the claim after it was checked with an independent expert. The ASA noted, however, that the study was carried out on only five households in Hertfordshire and that those households all included a child under three years old.

What I want to know is whether households in Hertfordshire have extremely clean toilet seats or extremely dirty chopping boards.
