Apples caused failed drunk-driving test?

A vendor piles up boxes of apples before closing his stall at a wholesale market in Nanjing, Jiangsu province March 10, 2009.

WARSAW (Reuters) - A Polish lawmaker who failed a drink-driving test said he had eaten too many apples, the website of daily Gazeta Wyborcza said Monday.

Asked why a traffic police check Sunday showed he had 0.7 units of alcohol in his blood, Marek Latas denied having drunk alcohol that day.

"I am diabetic, I ate a few apples before driving.

"I have been involved in no accident, I underwent a routine roadside check. I was confident there was no chance I had alcohol in my blood," said Latas, a member of parliament for the conservative opposition Law and Justice Party.

The prosecutor's office is investigating his case, the website said. In Poland, the legal limit for alcohol when driving is 0.2 units. Fermented apple juice can be used to make cider, an alcoholic drink.
