The cooling profile of hot-cooked mussels stored in domestic insulated coolers amongst food vendors in Prince Edward Island, Canada.

It is common during outdoor events on Prince Edward Island, Canada for vendors to store hot-cooked mussels in domestic coolers. Provincial legislation states that hot product should be maintained at a minimum of 60 °C. A study was conducted to ascertain how long mussels could be stored before the temperature decreased to less than 60 °C. Hot, cooked mussels were placed into coolers and the temperature measured every 10 min for 4 h. It was found that when the cooler was unopened, the mean temperature dropped to less than 60 °C in 56 min. For coolers opened every 10 min, the mean temperature decreased to less than 60 °C in 38 min. For coolers opened every 10 min with mussels removed, the mean temperature decreased to less than 60 °C in 52 min. It was concluded that mussels should not be stored for more than 30 min and temperature should be regularly monitored.
