A researcher became a caregiver at a day care chain for six months to observe childcare practices. The researcher saw caregivers who folled to wash their hands after assisting a child who had a cough. In addition, she noticed that caregivers placed the children's food on trays using their fingers rather than the tongs that were provided. The researcher used research to determine that more monitoring is needed to make sure that caregivers at this day care chain comply with sanitary regulations.
