New study pointed out that handbags of women are contaminated with bacteria much more than the numbers of bacteria found in a restroom.

One would hardly expect the most contaminated item to be the hand cream which contained more bacteria than a toilet seat. Mascara and lipstick followed suit with fewer bacteria as compared to the cream.
Tests also revealed that leather purses contain more bacteria because of their spongy structure and this makes it very conducive for the growth and spread of bacteria.
Researchers cautioned that women should clean their handbags more often and also use a antibacterial gel to clean their hands to stop the spread of these germs.
