Food is essential for people to survive. But contaminated food and water may lead to illnesses, some of which are potentially life-threatening. Foodborne illness occurs when you consume food contaminated with bacteria and other disease-causing microorganisms.
Sometimes, when individuals hear about foodborne illness, the first thing that usually comes to their mind is stomach-ache. However, this disease is more than just abdominal pain. This condition has other accompanying symptoms, such as vomiting, diarrhoea, fever and dehydration.
If you own a restaurant, it is important to monitor the quality and safety of the food you serve to your customers. It helps if you have completed a food safety supervisor course in New South Wales, either online or at an accredited school.
Here are some of the common types of foodborne illnesses:
Salmonellosis is a type of food poisoning caused by the Salmonella enterica bacterium. This bacterium is present in the intestines of birds, mammals and reptiles. It can spread to human through various foods.
Salmonellosis is more common in the summer. Children, babies, pregnant women, older adults and those with a suppressed immune system are more prone to this infection.
The common signs and symptoms of salmonellosis include diarrhoea, fever and abdominal pain. The illness can last for about 4 to 7 days, and most people will recover without any treatment. However, some people may need treatment or hospitalisation, especially when they suffer from dehydration.
Escherichia coli (E. coli) are pathogens that normally live in the digestive tracts of both humans and animals. E. coli may cause severe complications of bloody diarrhoea, such as anaemia and kidney failure, which could lead to death.
Having Clostridium botulinum can lead to a condition called botulism, a life-threatening foodborne disease. It is usually found in contaminated canned goods. These bacteria can only thrive in areas or products where there is no oxygen. The common symptoms of this disease include constipation, tiredness, drooling, irritability and paralysis.
You must ensure that the water you drink and the food you eat is clean. Foodborne illnesses usually occur when there is a problem regarding food handling and preparation. As such, all food handlers must undergo training and testing before they enter the food, tourism or hospitality industry.
