Case Study

• This is what happened the night before the outbreak of foodborne illness at a restaurant.

A junior cook worked right away after changing his uniform. He started to prepare the buffet’s set up 4 hours earlier than usual. He brought out a bowl of Caesar salad which hadn’t covered with cling film. He put it on the salad bar, but he forgot to switch on the bar’s display fridge.

He went on to prepare beef congee, and he left the cooked congee on the counter at room temperature. He stored the unused raw meats (beef) without covering them in the same fridge with sushi. Time to time, he covered his nose when he sneezes and carries on with food preparation right afterwards.

After the investigation into the outbreak of foodborne illness by the officer from the Food and Environmental Hygiene Department, he commanded “KEEP HOT FOOD HOT AND COLD FOOD COLD”

• Answer the following questions:
