The New York City Department of Health and Mental Hygiene's Division of Environmental Health works to prevent and control illness and injury related to environmental and occupational health risks through outreach, education, surveillance, and enforcement. With staff of 1,000, the Division covers a broad range of subject matter, including oversight of environmental investigations, lead poisoning, injury prevention, occupational health, food safety, childcare, radiation control, recreational and drinking water quality, air quality, climate health, vector control, veterinary public health and pest control. The Bureau of Food Safety and Community Sanitation (BFSCS) protects the public, including New York's most vulnerable citizens from a broad range of hazards that may pose a threat to health or safety. This includes hazards related to food safety wherever meals are served to the public, including restaurants, school cafeterias, mobile food vending carts, senior centers, and soup kitchens, first-hand and second-hand smoke for all places of employment and public spaces. BFSCS also monitors compliance with regulations in other facilities, such as tattoo parlors, correctional facilities, and homeless shelters. Additionally, BFSCS investigates environmental health complaints received from New York City residents.
