On the other hand there are a lot of certifications and for each certificate there is an audit while some parts are overlapping!!
A friend of me once made a excell file putting all the certification manuals together and found out that one audit could be enough to see if a producer was global gap, nature's choice, fruitnet, ipm, ........
And indeed sometimes when weather conditions etc are favorable Global Gap can even save costs. It are just the so many audits by different auditing companies that can make life more difficult and expensive for the producer.
Indeed the market is getting more competitive and prices are under pressure. But without Global Gap the produce will have far less chance to reach the shelves of the supermarket store.
TK: More comments followed, and as you can tell, the group has a decidedly international flavor. The various food safety "schemes" employed by British retailers were discussed. All in all, the thread points to the pressing need for harmonization of food safety certifications, both on a national and international basis. By the way, if you are not a member of the LinkedIn group, I will be glad to welcome you as a member.
