The Independent- Beware of the cat: Britain's hidden toxoplasma problem
This newspaper headline points out the massive risks of infection from Toxoplasma, a parasite carried by cats. Pregnant women are particularly vulnerable and infection can result in congenital birth deformities, blindness, dementia and even death.
This parasite can infect soil through cat excrement. Taking your shoes off before you enter your home and asking visitors to do the same can therefore help to reduce the risk of infection.
