More than 1,000 of the toxic spores have been found in the homes of hundreds of homes across the UK, and more than half of those are in the South East of England.

Some of the spores have also been found on the roof of the homes where a school has been placed in the aftermath of the Manchester Arena explosion.

A Home Affairs select committee report says the condition is a “potential public health emergency”.

The report said that because of the lack of education around mould exposure and the lack on-going testing and reporting of mold, “it is difficult to know how many people may be exposed to these spores”.

“Many households are exposed to mould on a daily basis, but the vast majority of these exposures are not detected and the risk to health is low,” it said.

“If you are a householder, or even a friend, or neighbour, or someone who lives close by, it is important that you get information and advice to help protect your home.”‘

Mold-free homes’The Home Affairs committee report said it was “extremely important” that anyone who was exposed to a mould-forming microorganism should get tested and treated.

The committee said the government should be making it a priority to test all homes for mould, and ensure “mold-proofing” was carried out on them.

“The lack of test facilities, and lack of testing of those in control areas, mean that there is a significant amount of potential for contamination,” the report said.

Mould-free housesThe report also called for the establishment of a national system for testing for mould in homes, and to ensure that people in control of mould are treated and tested.

It said the number of cases of mould-related illness in the UK had increased by more than 30 per cent in the last year.

The report recommends the establishment and funding of a National Mould-Free Homes Scheme to “ensure that no homes are left in need of remediation”.

It also calls for an investigation into the government’s failure to provide advice to the public and local councils on the importance of preventing mould from spreading in houses.

The government said it would not comment on the report.

“Mould is an extremely challenging environmental problem which is affecting our communities and local people,” a spokesperson for the Department for Communities and Local Government said. 

“The Home Secretary and the Health Secretary have both committed to tackling this problem.

We are working with the public to tackle the spread of mould and the wider threat to the environment.”

A spokesman for the National Mankineshed Council said the council was looking into the report and said the boroughs plan was to build a new building at the site.

“We are looking at the report, and we are working towards building a new house in Mankins Point, which is a lot closer to the site,” the spokesman said.

A spokesperson for Greater Manchester council said the area had been “blocked” from further redevelopment.

“It is disappointing to see the Home Affairs Select Committee report that highlights the challenges faced by people in Greater Manchester who live in blighted areas and homes with mould,” the council said.

“The council has been working closely with local authorities to address the problem and will continue to work closely with them to ensure all residents in Greater London have safe, quality homes.”

Residents will be offered free council house cleaning services.”‘

A real opportunity’Mould was first identified in the US in the 1980s, when people were complaining of headaches, nosebleeds and rashes.

Its spread in the 1970s and 1980s prompted a campaign to get rid of the mould and other germs in homes.

However, mould has become a major problem in Britain and around the world, as a result of the huge increase in the number and use of air conditioning and heating.

The Home Office has issued guidance for people living in homes with black mold, but this is still not compulsory.
