According to this widely circulated health warning, people should not eat raw or left-over onion because onions are "poisonous".
The fact is that onions are not especially prone to bacterial contamination. In fact, quite the opposite. Onions feature a variety of sulphur compounds that have antibact
erial activity. Furthermore, cutting an onion triggers the release of enzymes that initiate a chemical reaction producing propenesulfenic acid, which in turn decomposes to yield sulphuric acid.
It is the sulphuric acid that makes you cry by irritating the eyes! But sulphuric acid also inhibits the growth of bacteria. Also, a cut onion's surface dries out quickly, reducing the moisture that is needed for bacteria to multiply.
