Are they stern about using deodorant? Do they usher smelly citizens to showers? No. Community Hygiene Concern alludes delicately to that scourge of society - head lice.
Head lice! The critters! Along with their sidekicks scabies and threadworms, other parasites the charity is intent on overcoming, they threaten people everywhere.
CHC, set up in 1988 "to protect people and pets from parasites", says head lice "produce symptoms of minor medical consequence, but cause enormous social distress".
It also helps tackle Toxocara (dog and cat roundworm), which can cause blindness in humans.
The charity says that ignoring the villains has only served to boost their activities. "They thrive in a society that cannot bear to think about personal parasites and is too embarrassed to contemplate pet hygiene," it says.
Its remedy is the non-toxic Bug Buster kit. At £5.95, it's a snip for those who want to be part of the solution, not part of the problem.
