A family eat a chicken meal at a restaurant. Two days later, several members of the family have Salmonella food poisoning.
Give two symptoms of Salmonella food poisoning.
The chicken had not been cooked all the way through. Explain why cooking chicken thoroughly reduces the risk of Salmonella food poisoning.
In the restaurant kitchen, the raw chicken had been prepared on the same board as the salad. Suggest why this increases the risk of Salmonella food poisoning.
