New report calls for clean-up of public attitudes to hygiene

Tuesday, June 25, 2019

The Royal Society for Public Health has today published Too Clean or Not Too Clean?, a new report calling for an end to the myth that some people are being too hygienic for their own good. The report follows a national survey looking at public understanding and practice of hygiene, revealing that while the broad value of hygiene is understood, there are key misconceptions and gaps in understanding that could be increasing the risk of spread of infections. [1]

Key findings include that:

• There is substantial public confusion about the relationship between cleanliness and hygiene: two in five (61%) believe dirty hands from outdoor play are likely to spread harmful germs, despite there being little evidence that outdoor dirt carries harmful microbes. [2]

• Over one third of the public (36%) believe dirt is usually or always harmful.

• Although many people can identify lifestyle factors responsible for preventing children from coming into contact with bacteria that are good for their health – such as using too many antibiotics (59%) and spending too much time indoors (56%) – almost as many believe incorrectly that keeping one’s home ‘too clean’ also has this effect (55%).

• Men are more than twice as likely as women to think there’s low or no risk associated with not washing hands with soap after using the toilet (16% vs 7%), or after handling raw meat (8% vs 4%).

• The public generally agree that good hygiene is important, including for its role in reducing pressure on the NHS (73%) and in tackling antibiotic resistance (50%).

The report emphasises that getting outdoors and interacting with friends, family, pets and the natural environment is important for getting exposure to ‘good bacteria’ – which is vital for building a healthy microbiome (the array of micro-organisms hosted by our bodies). However, misleading headlines from sections of the media appear to have reinforced the myth that children ought to be exposed to harmful germs to build their immune system – a harmful and discredited myth believed by as many as one in four (23%) of the public. This misconception is particularly dangerous as it heightens a child’s risk of infection, which in turn requires antibiotics that can harm their microbiome.

In fact, a healthy microbiome is best supported by a more focused approach to hygiene – targeted hygiene. You can learn more about targeted hygiene in UKCPI's hygiene golden rules section.
By focusing hygiene in the places and times that matter, it is possible to break the chain of infection and at the same time stay exposed to the ‘good bacteria’ required for a healthy microbiome.

The eight most crucial times to practise hygiene are:
1. During food handling.
2. Whilst eating with fingers.
3. Using the toilet.
4. Coughing, sneezing and nose blowing.
5. Handling and laundering ‘dirty’ clothing and household linens
6. Caring for domestic animals.
7. Handling and disposing of refuse.
8. Caring for an infected family member.

RSPH is calling for the widespread adoption of targeted hygiene as the most effective way of breaking the chain of infection. Schools, the media, and manufacturers of hygiene products all have a responsibility to advocate for clear messages about targeted hygiene – dispelling myths, improving the wellbeing of our children, and slashing the risk of infection outbreaks.

Professor Lisa Ackerley, RSPH Trustee and food hygiene expert, said:
“Getting outdoors and playing with friends, family and pets is great for exposure to ‘good bacteria’ and building a healthy microbiome, but it’s also crucial that the public don’t get the wrong end of the stick – this doesn’t need to get in the way of good hygiene. Targeted hygiene undertaken at the crucial times and places is a way of preventing infection that is cheap on time and low effort, and still exposes you to all the ‘good bacteria’ your body benefits from.
“Good hygiene in the home and everyday life helps to reduce infections, is vitally important to protecting our children and reducing pressure on the NHS, and has a huge role to play in the battle against antibiotic resistance. It is good to see the majority of the public on board with these key messages, but at the same time worrying that key misconceptions persist. Failing to practise targeted hygiene at the critical places and times can have serious consequences, as the recent outbreaks of Listeria serve to remind us.”

Professor Sally Bloomfield of London School of Hygiene and Tropical Medicine and Chairman of the International Scientific Forum on Home Hygiene commented:
“Government health agencies also agree that practising good hygiene is vital for safeguarding health and reducing antibiotic prescribing. The 2019 UK Antimicrobial Resistance Action Plan says ‘Health providers can only do so much; when it comes to preventing infections in the community, the public have a huge part to play.’
“The problem is that we have become confused about what hygiene is, and how it differs from cleanliness. Whereas cleaning means removing dirt and microbes, hygiene means cleaning in the places and times that matter – in the right way – to break the chain of infection whilst preparing food, using the toilet, caring for pets etc.
“Growing awareness that exposure to “good” microbes in order to build a healthy microbiome is essential for health means we need to view our microbial world differently and adopt appropriate lifestyles. Targeted hygiene offers a lifestyle which maximises protection at times when we risk exposure to harmful microbes, but at the same time maximizes ongoing interaction with microbial friends from human, animal and natural environments.”
