O104 EHEC

It can't be food - far too many female victims.

[update]

It can't be *only* female, a few male victims.

It must be something mostly women use.

My tip: Lipstick, perhaps?

Update; Well ... after ruining many a cucumber-farmer (mainly in Spain), closely followed by lettuce and tomato farmers almost everywhere, they say that they *definitively* traced it to sprouts, usually served as part of a salad. IF so THEN it would appear that 'leaf-eaters' are overwhelmingly female. No offence, ladies... and lipstick can make you look prettier, no danger there.
