Try not to eat or drink poison, most of you do so every day.

Interesting article in the Daily Express on 30th August on how a slice of lemon in your drink, part f the article reads:

Whether it be an ice cold glass of your favourite fizzy drink or a slimline gin and tonic, a slice of lemon is always a refreshing addition.

But did you know the microbes found on your citrus wedge have the potential to cause infectious diseases?

This comes after it was revealed THIS everyday habit is "as dirty as licking your toilet".

A study published in the Journal of Environmental Health in 2007, involved researchers swabbing lemon slices that were on their drinks at 21 different restaurants.

They found almost 70 per cent of the samples produced some sort of microbial growth, including 25 different microbial species.

The researchers concluded: “The microbes found on the lemon samples in our investigation all have the potential to cause infectious diseases at various body sites, although the likelihood was not determined in this study
But it doesn't stop there, in the Express on the 11th August

So it may come as a surprise to learn that refilling your water bottle without washing it has been branded as dirtier than licking the toilet.

New research from treadmillreviews has found that refilled water bottles are covered in germs.

Researchers lab-tested reusable water bottles after each had been used by an athlete for a week.

The bottle with the highest number of bacteria – over 900,000 colony forming units per square cm on average – had more bacteria than the average toilet seat.

The research, shared with, found the average person’s water bottle had 313,499 CFU per square cm.

The germ-ridden bottles are caused by a lack of washing mixed with sweat and germs encountered on a daily basis.

Even more stomach-churning was the news researchers found 60 per cent of the germs they discovered on the water bottles were able to make people sick.

However there are ways to make water bottles less germ-covered.
 Which should be enough to examine everything we do where eating utencils, cups and plates, water bottles are concerned.

Some useful hints from these articles include:

1. Firstly, don’t use a slide-top bottle as it was found to be the worst for germs, with 933,340 CFU per square cm.

2. Squeeze top and screw-top bottles came in second, with around 160,000 CFU per square cm.

3. But the cleanest bottles were straw-tops, which had just 25,400 CFU per square cm.

4. Drinking from a stainless steel bottle is healthier than from a plastic bottle, researchers discovered.

What a load of quasi-scientific rubbish. This from the Treadmill Reviews link:
We swabbed three water bottles for each different type of water bottle (screw-top, slide-top, squeeze-top, and straw-top) for a total of 12 swabs. Each water bottle had been used by an athlete for a week without being washed. EmLab P&K performed all laboratory testing.
In other words, the bacteria identified came from the athletes themselves. Unless they were suffering from enteritis or pustulating injuries whilst exercising (unlikely!) the organisms are part of the athletes’ normal flora, and harmless to themselves.
A qualified medical microbiologist.

Thanks for useful information. Are you saying there is no need to wash waterbottles after use at all?

Effectively, yes that is what I am saying - PROVIDED THAT they do not let others drink from the same bottle. The risk to others is extremely small, but exists. One of the most famous examples of a symptomless carrier is that of “Typoid Mary”. A quick google will tell you about her!

The rule here is whenever “Experts claim…” or “Scientists claim…” is the headline, ALWAYS go back to the original source and dig for the data. These articles are churned out by junior hacks/subbies that just regurgitate stuff that they NEVER validate.

It used to be called investigative journalism. Now it’s just column inches to fill the space between the income generating display ads.

I omitted to state the obvious … if the bottle falls to the ground, gets covered in cow poo or the like, then washing it is advisable!
