Environmental and occupational health is a very broad field within public health which includes ensuring that food is inspected  for possible contaminants, workplaces and public facilities (such as swimming pools and daycare centers) are free of possible  injury-causing situations or infectious disease-causing issues, and health rules are followed. This may involve collecting data  and analyzing many types of work environments and work procedures. Specialists inspect workplaces for adherence to  regulations on safety, health, and the environment. These professionals inspect, test, and evaluate workplace environments,  equipment, and practices to ensure that they follow safety standards and government regulations, and prepare written reports  on their findings. The field also includes toxicologists who research potentially harmful chemicals (in food, drugs, or consumer  products), individuals who manage environmental health research projects, people who design workplaces to ensure that  workers are less likely to be injured, and environmental policy specialists.
