People with reduced resistance to infection, the elderly and pregnant women should avoid eating doner kebabs because of the high levels of bacteria many contain, according to the consumers association Consumentenbond.

The organisation tested 49 different doner kebabs from Groningen, Utrecht, Amsterdam, Rotterdam and Breda and found bacteria which could make people ill in half of them. In five cases, the food was found to contain bacteria associated with faeces.
High levels of bacteria indicate the food is either too old, has been kept warm for too long or that hygiene standards are poor, the association said.
