Other harmful toxins
Exposure to harmful chemical and toxins can affect the unborn baby. For example, if you work regularly with chemicals or around x-rays, you should take extra precautions to avoid exposure before and during your pregnancy.
If you have a dog or a cat, you may also be at risk from toxoplasmosis – a disease caused by parasites that live in certain mammals. You can become infected by coming in contact with cat faeces, either in a litter box or in the soil, as well as by eating some raw meats. Get someone else to change litter boxes for you, or wear gloves when you do it. Infection during pregnancy may cause premature birth or low birth weight.
