They did not know that they had increased the chance of bacterial infection from dozens of people who had . chewed the pen before.

However, bacterial infection is not something too dangerous, because most microorganisms in the human body are benign. The real harm here is a component in pen case or ballpoint pen - a chemical called bisphenol A (BPA) .

BPA is a chemical used in the plastics industry.

BPA is a chemical used in the plastics industry. This substance has been shown to have women's effects that cause neurological disorders, muscle weakness, allergies . only in very small amounts. Even research has shown that BPA can stimulate the growth of cancer cells.

There was a time when plastic bottles also contained BPA.
