The onions wont contaminate into bacterial formation. This is just opposite. The onions have some good features of sulphur compounds, it have antibacterial activity. While cutting the onion, it release the enzymes of chemical reaction which produces propenesulfenic acid, which decomposes sulphuric acid.
