Professor Hugh Pennington, from the University of Aberdeen, one of Britain's leading infection experts, said: "I would like to get rid of washing-up bowls altogether. They are an absolute menace."
Professor Pennington said that placing chopping boards and knives teeming with germs together with plates and glasses in a plastic bowl created an ideal environment for the spread of bugs.
Colleague Professor Sally Bloomfield, from King's College, London, said there was a high risk of salmonella being transmitted from chopping boards to plates in the washing-up bowl.
The experts said disposable paper cloths should be used instead of tea-towels that could easily spread infection.
They also recommended using "good old fashioned bleach" in the kitchen rather than newer anti-bacterial products that were only vaguely effective.
Thousands of cases
Last year there were more than 17,000 reported cases of salmonella poisoning in England and Wales and 55,000 cases of infection by campylobacter, a common bug that causes stomach upsets.
Estimates for unreported cases pushed the number of salmonella infections up to more than 50,000 and campylobacter to more than 400,000.
Viruses were responsible for a vast number of infections, possibly amounting to more than three million cases.
Professor Pennington said: "One in five of us each year will get diarrhoea.
"To me, that's a public health scandal, because it's preventable."
He said it was best to get rid of the washing-bowl and instead use the whole sink.
