National standards, practices and techniques are provided for milk, ice cream, poultry, eggs, meat, produce and seafood. Current modes of surveillance and evaluation as well as appropriate control measures are provided for each of the above areas. Chapter 5, Insect Control discusses scientific, technological, and general information about various insects of public health significance including fleas, flies, lice, mites, mosquitoes, and roaches. There is a substantial discussion of the many diseases transmitted by insects including African Bite Fever, Bubonic Plague, Chagas Disease, Colorado Tick Fever, Dengue Fever, Ehrlichioses, Encephalitis, Lyme Disease, Malaria, Rickettsial Pox, Rocky Mountain Spotted Fever, Scabies, Scrub Typhus, Tularemia, Typhus Fever, Viral Hemorrhagic Fevers, Yellow Fever. Included in the text are the national standards, practices, and techniques utilized to conduct surveys, methods of prevention and controls of the insects. Further there is a discussion of emerging and reemerging insect borne diseases including why this is occurring. Integrated pest management is a special topic. Chapter 6, Rodent Control discusses the characteristics and behavior of murine rodents and deer mice, how they affect humans and the various diseases that they cause. National standards, practices and techniques are established for rodent poisoning and trapping, food and harborage removal, and rodent proofing. A special feature is the discussion of an actual working community rodent control program. Chapter 7, Pesticides discusses current issues, current laws and the effects of pesticides on groundwater, surface water, land, food, air and people. The various categories of pesticides and current allowable usage of inorganic insecticides and petroleum compounds, chlorinated hydrocarbons, organophosphates, carbamates, biolarvicides, and insect growth regulators are discussed. Chapter 8, Indoor Environment discusses indoor air pollution, housing, health and the housing environment, human illness, monitoring environmental disease, residential wood combustion, environmental tobacco smoke, carbon monoxide, radon gas, volatile organic compounds, asbestos, molds, bacteria and other biological contaminants, environmental lead hazards, noise, accidents and injuries. National standards, practices, and techniques are provided for all areas of the indoor environment, and survey techniques and housing studies are included. Chapter 9-Institutional Environment discusses the complex environment and potential for disease in nursing and convalescent homes, old-age homes, schools, colleges, and universities, prisons and hospitals. There are in-depth discussions on the potential for spread of disease through air, water, fomites, surfaces, people, food, laundry, insects and rodents, laboratories and biohazards, and surgical suites. Within the hospital setting there are extended discussions of heating, air conditioning, and laminar flow, housekeeping, laundry, solid and hazardous waste, maintenance, plumbing, food, hazardous chemicals, insects and rodents, radioactive materials, water supply, emergency medical services, fire safety and patient safety programs. Handwashing and hospital environmental control is explained in depth including the various microorganisms that may be transmitted by hands. There is a special discussion on laboratories and bio hazards including bacterial agents, fungal agents, parasitic agents, prions, rickettsial agents, viral agents, arborviruses and related zoological viruses. There are additional discussions on human immunodeficiency virus, hepatitis B virus, hepatitis C virus, tuberculosis, resistant organisms. Emerging and reemerging infection problems are of great significance. Hospital acquired infection and routes of transmission are significant problems. Occupational health and safety problems in the hospital are analyzed. The most recent CDC guidelines for all these areas are included. A significant number of inspection and survey forms are included in order for the reader to get a better understanding of specific problems in a specific institution. Chapter 10-Recreational Environment includes problems and solutions to problems in water quality, water supply, sewage, plumbing, shelter, food, solid waste, fish handling, stables, swimming and boating. Chapter 11-Occupational Environment includes a discussion of the interrelated challenges of various pressures in the environment. It includes physical agents such as sound, non-ionizing radiation, ionizing radiation, hot and cold temperature extremes. It also includes discussions of chemical agents such as toxic chemicals, flammable chemicals, corrosive chemicals, reactive agents. It includes discussions of biological agents. Ergonomics is an essential part of the chapter.
