Transcript: When you’re pregnant, even simple tasks—like microwaving a pizza or changing the litter—may seem risky. Most day-to-day household tasks are perfectly safe for women who are pregnant.  For example, there is no reason why an expectant mom shouldn’t use the microwave. There is no evidence that the minute radiation emitted from a microwave can even reach, let alone harm, a fetus. On the other hand, expectant moms should not change a cat’s litter box. That’s because of a parasite infection called toxoplasmosis, that is transferred from cat feces and is present in places where a cat does its business. Toxoplasmosis isn’t harmful to adults, but it can cause neurological damage in a developing fetus. People can also be exposed to toxoplasmosis when gardening, so expecting moms should let their partner take care of the yard work—or at least wear gloves when performing these tasks. Pregnant women should be particularly careful about lead exposure around the house. Exposure to peeling lead paint, or to lead in general, can be especially dangerous during pregnancy. That’s because lead exposure can lead to a lower IQ for the baby, as well as to a premature birth. If you’re worried about lead, get a blood test from your doctor to determine your levels. Remember: The cat and your microwave have not suddenly become the enemy. Be smart and you’ll be safe.
