A major European health agency report warns that widely-used fungicides sprayed on crops to prevent plant diseases may be creating resistant fungi that can infect humans and make medical treatments ineffective. The study found that about 10,000 tonnes of these azole fungicides are used in Europe annually, and their residues accumulate in the environment where they can cause harmful fungi to become resistant to the same medicines doctors use to treat patients. The report calls for urgent action to better monitor this problem and prevent resistance through smarter use and regulation of agricultural fungicides.
