Talks to end council worker strikes which have seen rubbish pile up in the streets of two thirds of Scottish local authorities are continuing amid warnings over the impact on public health.
Bosses at Public Health Scotland have told councils that the “decontamination of public areas where bins have overflowed may be required”.
It comes as the organisation warned that “if organic waste builds up it can become a risk to human health”.
Unison and GMB members in 20 local authorities began the first of two four-day strikes on August 26.
They joined workers represented by Unite who began a week-long strike in 14 councils on Wednesday.
People are being advised to double bag items such as food waste and used nappies or put them in containers.
Public Health Scotland said the spread of strike action by council workers – sparked by a dispute over pay – may result in “more widespread waste accumulation”.
Scottish Deputy First Minister John Swinney has already said the piles of rubbish building up throughout Edinburgh are “deeply concerning” for public health.
The waste strikes are scheduled to last into next week – with further dates for action already fixed if the pay row can not be resolved.
Public Health Scotland has said: “Organic waste includes food waste, animal waste (from food or excrement), human waste (including nappies) and manure.”
The health body said the impact of waste on health is “varied” and “may depend on numerous factors, including the nature of the waste and weather conditions that may accelerate decomposition of waste”.
It said: “There are some simple precautions which people can take in order to reduce the possible health impacts of waste.
“When handling waste at home, people should always wash hands thoroughly. Where possible, organic waste and medical waste should be stored in containers.
“If containers are not available, waste which is likely to rot or decompose should be double bagged.”
It said people should avoid contact with rubbish in public areas.
And it warned: “The accumulation of waste may increase fire risk so households may wish to consider their fire safety preparedness.”
As well as the strike by waste workers, council staff working in schools and education in parts of Scotland are preparing to walk out next month if no deal on pay can be reached.
Glasgow City Council, Scotland’s largest local authority, has already said this will see its primary schools and nurseries forced to close for the three days of the action, currently scheduled to take place between September 6 and 8.
