Cases of food poisoning are on the rise, with the most common culprit being poor food hygiene. There are simple ways you can prevent it. — Dr Rob Hicks (cited in BBC)
What is it?
According to wikipedia, food poisoning, also referred as foodborne disease, is any illness resulting from the consumption of food and drink.
It is a common, usually mild, but occasionally deadly illness often accompanied by fever, muscle aches, shivering and feeling exhausted.
Food can be contaminated by many different disease-causing microbes, pathogens and poisonous chemicals, or other harmful substances.
As a result, the symptoms of food poisoning appear very different, including nausea, abdominal pain, vomiting, diarrhea, gastroenteritis, fever, headache and fatigue.
What causes it?
Food poisoning arises from someone eats food or drink that contaminated with bacteria or toxins, such as poisonous mushrooms and vegetables that sprayed with pesticides.
Food might be polluted by improper handling, preparation, or storage.
Commonly recognised food poisoning infections include:
- Campylobacter infection is the most frequent cause. It likes to live in milk, raw poultry meat and the intestines of healthy birds.
- Salmonella. It may spreads from the intestines of birds, reptiles and mammals to humans by eating animal organs, such as kidney and liver. Salmonellosis, the illness it causes, can invade the bloodstream and cause life-threatening infections.
- E. coli O157:H7. This is a bacterial pathogen that has a reservoir in cattle and other similar animals. Human illness typically follows consumption of food or water that polluted with microscopic amounts of cow feces.
- Norwalk-like virus. It spread primarily from one infected person to another. For example, infected fishermen can contaminate oysters as they harvested them; infected kitchen workers can contaminate food as they prepare it.
How can I prevent it?
Here are some tips from the Centers for Disease Control and Prevention
- Make sure that food from animal sources (meat, dairy, eggs) is cooked thoroughly or pasteurized.
- Carefully select and prepare fish and shellfish to ensure quality and freshness.
- If you are served an undercooked meat or egg product in a restaurant, send it back for further cooking. You should also ask for a new plate.
- Wash your hands, cutting boards, and knives with antibacterial soap and warm to hot water after handling raw meat, poultry, seafood, or eggs.
- Do not thaw foods at room temperature. Thaw foods in the refrigerator and use them promptly.
- Mother’s milk is the safest food for young infants. Breast-feeding may prevent many foodborne illnesses and other health problems.
What’s the treatment?
According to BBC, most infections begin several hours to several days after consumption of polluted food and will last 24 to 48 hours.
During this period fluid is often lost from vomiting and diarrhoea. To prevent dehydration, drink plenty of cooled boiled water and use rehydration powders if the symptoms continue.
A health care provider should be consulted in the following situations: (cited in Mediac8 Family Health)
- High fever (temperature over 101.5 F, measured orally)
- Blood in the stools
- Prolonged vomiting that prevents keeping liquids down (which can lead to dehydration)
- Signs of dehydration, including a decrease in urination, a dry mouth and throat, and feeling dizzy when standing up.
- Diarrhoeal illness that lasts more than 3 days
