That is exactly the point that the Frenchman was making. They are prepared to take a risk so that they can have interesting food, and they make a personal choice in order to experience it. The French have a different attitude towards risk, and that extends to a lot of activities. If a UK food safety geezer went to a summer market selling thick local cream he would go ballistic.
There's more to it than that though. It's certainly an image they like to project but the French don't have as relaxed an attitude to food safety as anecdotal evidence might suggest. They are subject to exactly the same EC food safety law as we are in the UK and how they enforce it is subject to external scrutiny and monitoring. National stereotypes and holiday experiences play a part in views on this, of course, and there will be some real variations across the EC but there is no great difference between the two countries.
I will use my own anecdotal evidence, as "a UK food safety geezer", in that I have colleagues working for UK food companies operating in France and a French food safety officer working in my team. His own experience is that what we do in the UK is very similar to France. The main difference is that the French food safety officers operate in a more draconian enforcement environment. They have similar powers to us but the courts are much more biased against the defendant and more or less assume guilt at the outset. I also have a friend who set up a B&B in France and found the experience with the French food safety system far more intimidating and bureaucratic than here.
I'm not sure why I would be expected to go ballistic over French thick cream, though. I don't worry that much about my food. About the only no-no for me is raw milk, desite being brought up on it and loving its taste.
