Customers are advised to wash their hands thoroughly after visiting the supermarket in an attempt to curb the spread of the dreaded norovirus. The Health Council of Swansea Bay University said buyers should be aware of the large number of people handling trolleys every day, potentially carrying insects and viruses.
"The handles of supermarket shopping carts can be handled by hundreds of people every day.
"Please, wash your hands thoroughly with soap and water when you return home, to reduce the risk of contracting an infection such as norovirus, colds or flu." . "
Joanna Walters, Director of the Infection Control and Infection Control Department, also asked people to wash their hands after touching "TV remotes, your cell phone, switches, doorknobs" and not to "Share the towels with the members of your household".
