Australia: Scientists warn of emerging Vibrio risk; say there should be mandatory reporting

Researchers have called for more focus on Vibrio infections in Australia because of the potential impact of climate factors and a growing industry. Australia currently produces almost 8,900 tons of oysters per year with expanded production expected in the next few years.

Since then, sporadic cases have been ...
