Random checks carried out on Dutch cucumbers, tomatoes, bell peppers and lettuces have not found traces of the EHEC bacteria responsible for a serious outbreak of E-coli poisoning in Germany, the market garden product board says.

The tests were carried out by a German laboratory.
Some 16 people have died so far, 14 of whom were women. Some nine cases have been identified in Netherlands.
The source of the outbreak has not yet been identified. At one time it was thought Spanish cucumbers were to blame but they have since been cleared.
Dutch cucumber exports to Germany have collapsed since the outbreak began.
