China to restrict fly numbers in its public toilets
New measures planned to improve toilet hygiene standards

Chinese Health Ministry is planning to improve the hygiene standards of China’s public toilets – it even intends to restrict the number of flies in them. Under the new requirements, no more than three flies will be allowed per square metre in each toilet.
At the most, only three flies will be allowed per square metre in stand-alone public toilets. Only one fly will be allowed in public toilets built within other facilities, according to the new draft hygiene standards.
The new requirements classify all public toilets into four classes according to their odour levels. These are: no odours; slight odours; apparent odours; and strong odours.
Under the new rules, no toilet will be allowed to have more than a slight odour. Odour levels, caused by ammonia and hydrogen sulphide, will be evaluated by special teams.
China has long been notorious for its dirty public toilets. The new draft regulations reflect the government’s determination to change this.
