A

One hot, summer day, you returned home late from school and were very hungry. You opened the refrigerator, saw some left-over chicken, and ate it quickly. Several hours later, you felt very sick. Your stomach was painful and felt as if it had turned to liquid. You had to make frequent visits to the washroom. You felt unwell for several days and after you recovered, you thought to yourself – “It must have been something I ate.” You were probably right.

“Food poisoning” is the name given to the unpleasant symptoms you get when you eat food which is contaminated with certain types of harmful bacteria or by the poison produced by some bacteria. Contrary to popular belief, the bacteria which cause food to rot are not the most common do not usually eat food which is noticeably “off”. Usually the contaminated food which does cause food poisoning looks, smells and tastes alright.

Food poisoning is not infectious, but outbreaks of the illness often affect more than one person. The reason is that the bacteria which cause food poisoning can infect the large quantity of food prepared for many people. However, it does not follow that everybody who eats the contaminated food becomes ill and nobody knows why some people seem to escape doing so.

Food poisoning is so common nowadays that almost everyone has suffered from it, especially people who live in urban areas. This is so because city dwellers are used to eating mass-produced food in public areas where hygiene is often neglected. As people become familiar with the symptoms of food poisoning, few bother to visit their doctor when they have one of the milder forms of this illness, so it is very difficult to say just how widespread it is.
