Public Health England has issued advice following cases of E.coli on the Isle of Wight.
There have been 10 cases of E.coli infections since September.
Health specialists are reminding people to make sure their hands are washed before eating or preparing food, or after contact with animals.
The illness causes diarrhoea and stomach pains and in rare cases can result in hospitalisation.
PHE is working with environmental health officers from Isle of Wight Council, and is waiting for results on a number of unconfirmed cases.
