Seems like another one of those things we've been doinf for ages has wound up on the "Things we can't do anymore" list... *sigh...
I know they're probably right, but i can't help but wonder "What next?"

Don't reuse plastic bottles
YOU could be drinking a cocktail of germs and bacteria if you store water in a reused plastic bottle.
Research has found that reusing such plastic bottles could be very unhealthly indeed.
A study published in the Canadian Journal Of Public Health found bacteria and chemical compounds in water from bottles that had been repeatedly washed and reused.
Based on water samples collected from young schoolchildren, researchers from the University of Calgary found found faecal coliform - a bacteria found in human faeces - in nearly 9 per cent of the samples.
It also found a toxin called DEHA in some. DEHA has been found to cause weight loss and liver problems, and is also suspected of causing cancer.
Mineral water and soft drink bottles are made of a plastic called polyethylene terephthalate, meant only for one-time use.
Associate Professor Simo O Pehkonen from the National University of Singapore's Chemical and Environmental Engineering department said that frequent washing would break down the plastic.
The chemical compounds then leach into the bottle's contents.
He said: 'Bacteria builds up on the walls of the bottle. If you use it maybe six times, it is still okay. If you use it for a prolonged period, the bacteria will form colonies and you can't even see it.'
Head of the Agri-Food and Veterinary Authority's (AVA) Food Control Division Seah Huay Leng agreed that the bottles were intended for one-time use only.
A spokesman for F&N Coca-Cola (Singapore) also advised customers not to reuse drink bottles as they are difficult to properly sterilise.
The best place for such bottles is therefore a recycling bin.
