Ron - there are a lot of concerns with black mold exposure. Do a Google. A couple years ago there were many 'alerts' about the prevalence of black mold and heart issues were just some of the complications. I recall in my FM health network, there were numerous teleconferences about the toxicity and systemic implications. Check www.mercola.com.... at the time he was actively publishing news.
The remediation of black mold requires certified experts dealing with such as it's very difficult to get rid of, apparently.
Sorry you have this concern right when you are getting ready for your Bordeaux trip.
Best to you,
Jackie
