Is It Safe? with Guest Amy Ziff

How do we know something is safe? From lotion to food to soap and shampoo, we interact with so many different items in a single day. Who is checking that these items are safe? Amy Ziff was a journalist living in Silicon Valley who asked these questions when twins were having allergic reaction to otherwise normal items such as pillows and diapers. She had an older child who did not have any sort of reaction to these items. What was happening with her younger children? What chemicals were going into household items? Are these all listed on packages? If not, how did Amy figure out what was contained in various items? Even when doing the research, how are we able to filter what is truth and based in science rather than a blogger's speculation?
