Animal waste and refuse

A laboratory may dispose of animal waste and refuse onsite (e.g., incineration) or may use a contract service for pickup and disposal. Some animal waste and refuse may... 

Containers with tight-fitting lids should be used for the temporary storage of animal waste and refuse before disposal to minimize vermin infestation, odors, disease hazards, and environmental contamination. 

A laboratory may dispose of animal waste and refuse on site (e.g., incineration) or may use a contract service for pickup and disposal. Some animal waste and refuse may meet EPA s definition of hazardous waste (e.g., waste or refuse from animals treated with hazardous materials or animals carrying infectious diseases) and must be disposed of in compliance with EPA regulations issued under the RCRA. Waste and refuse from animals treated with radioactive... 

Do the facilities provide for the collection and disposal of all animal waste and refuse or for safe sanitary storage of waste before removal from the facility ... 

At the other end of the material flow, facilities need proper provisions for the collection and disposal of all kinds of wastes, e.g. animal waste and refuse or contaminated water, soil, or other spent materials. If such waste cannot be disposed immediately provision has also to be made for safe sanitary storage of such waste before removal, by appropriate transportation procedures. 

Storm water runoff from cities and villages presents another problem. This runoff contains salts from road deicing, street refuse, animal waste, food litter, residue from atmospheric deposition of sulfuric and nitric acid, metals, asbestos from automobile brakes, rubber from tires, hydrocarbons from motor vehicle exhaust condensates, oil and grease, soil and inorganic nutrients from construction sites, and a variety of other chemicals. Research shows a heavy impact of urban nonpoint pollution on freshwater quality (World Resources Institute, 1988). 

Collection of chemical carcinogens, all waste products, animal carcasses and other materials from the laboratory should be performed by designated personnel on a scheduled basis or when necessary. The suspect or carcinogenic materials should not be placed on uncontrolled loading docks for pickup by general refuse collection personnel. At the National Institutes of Health, the special collection of hazardous materials, including chemical carcinogens, is done by personnel of the Fire Department. In the instance of one of the NCI contractor sites, Frederick Cancer Research Center, located at a military post, personnel from the safety offices perform this service.

Medical waste has been a growing concern because of recent incidents of public exposure to discarded blood vials, needles (sharps), empty prescription botdes, and syringes. Medical waste can typically include general refuse, human blood and blood products, cultures and stocks of infectious agents, laboratory animal carcasses, contaminated bedding material, and pathological wastes. 

Whether due to reduction in TdO activity, reduced glyconeogenesis, or both, Weber et al. (1994) proposed that an initial increase in tryptophan levels result in some initial feed refusal, which in turn initiates the wasting of body mass and increases the supply of tryptophan with which the animals cannot deal. A vicious cycle develops which results in strongly elevated tryptophan levels and increased serotonin turnover, which acts as an appetite suppressant. 

Waste Fats.—Under this classification may be included marrow fat, skin greases, bone fats, animal grease, melted stuff from hotel and restaurant refuse, and similar fatty products. The following is a fair typical selection —...
