From next month, shoppers who enter large retailers may want to take reusable carrier bags with them as the Government imposes a blanket 5p charge on each one used.
Retailers that employ more than 250 staff nationwide will have to charge for each carrier bag from October 5, but staff and customers may face confusion, as many items are exempt.
For example, bags solely used to contain wholly or partly unwrapped food such as loose fruit and vegetables won't carry a charge, according to the guidelines.
The same can be said for live aquatic creatures along with razor blades and knives. Meanwhile, bags intended to be used solely to contain uncooked fish or fish products, meat or meat products or poultry or poultry products are also exempt.
This could lead to confusion at the tills as the quirks are understood and digested in the coming months.
The move from the Department for Environment, Food and Rural Affairs is aimed at stopping the unnecessary use of plastic carrier bags – and tonnes of litter they produce each year, which in turn damages wildlife.
It is hoped it will encourage people to reuse them or buy 'bags for life.' Last year, 8.5billion plastic bags were dished out at British supermarkets alone, a 200million increase on a year earlier.
This is the equivalent of nearly 150 per person. It would mean the average person would see £7.50 added to their food shop over the year, if charged for each bag used.
Similar 5p charges are already in place across Scotland and Northern Ireland, although critics have questioned why the scheme does not extend to small and medium-sized stores.
The Government argues it is to reduce the administrative burden on small and medium-sized businesses. They can however charge on a voluntary basis if they wish.
Ministers have also been accused of a tax grab after it emerged VAT will apply to sales of bags.
This means the Treasury will pocket almost 1p for each one sold and estimates show it stands to make around £19million a year.
I'd like to bet that the incidence of food poisoning soars as salmonella is spread from one carrier bag full of shopping to the next!
