What to do if you or anyone in your party falls ill (food and water)
If you’re unfortunate enough to fall ill tell your travel company or your accommodation provider straight away. They should be able to help you get medical help if necessary and if they have provided your meals they will be able to investigate the source of the problem.
If you suffer from diarrhoea there are a number of things you can do. See the NHS Choices website for details.
If you fall seriously ill and need to go straight to hospital contact the emergency services. The standard emergency services number in the European Union is 112.
