Family and friends of LeBlanc are now working together to raise awareness of vibriosis which causes around 100 deaths a year in the US. In warmer months the disease is more rampant and symptoms include diarrhoea, nausea, fever and chills.
People are most likely to contact the bacteria if they eat raw or undercooked seafood or have a wound exposed to sea water.
LeBlanc's partner Vicki Bergquist said: "If they really knew what could happen to them and they could literally die within 48, 36 hours of eating raw oysters, is it really worth it?"

The bacteria called vibriosis is found in oysters and other types of seafood and can be fatal in people with a weakened immune system.
