2297/94 has nothing to do with bananas Tim, straight or otherwise! You mean 2257/94:
Commission Regulation (EC) No. 2257/94 of 16 September 1994 laying down quality standards for bananas, sometimes referred to in the media as the bendy banana law, is a
European Union regulation specifying classification standards for bananas, which took effect on 1 January 1995.
[1] It was replaced by Commission Implementing Regulation (EU) No 1333/2011 of 19 December 2011 laying down marketing standards for bananas, rules on the verification of compliance with those marketing standards and requirements for notifications in the banana sector with effect as of 9 January 2012. [Wikipedia]
It only states that bananas shall be "free from abnormal curvature", but gives no guidance on what constitutes abnormal. Oh, and it was an EC Regulation, not a Directive.
Sorry for the pedantry but I used to deal with this sort of thing for a living.
