The problem with this relates directly to false positives caused by hand sanitizers. The positive is caused by the inhalations of the vapors, not the absorption by the skin. Obviously this same problem can occur when someone cooks with alcohol. Wine seems like it would be harmless as the alcohol content, and thus the resulting vapors, are low--however, one should be careful when using liquor. That said, one should only be concerned if they're taking a test shortly after cooking and the test has a low detection level such as 100ng/ml.
