Livestock Confinement Dust and Gases
- What are the sources of health hazards to workers in confined animal operations?
- What are the symptoms that indicate that the health of workers in confinement operations is adversely being affected?
- Other than the pollutants themselves, what other factors influence worker health?
- What are some of the management options that will enhance worker safety?
Iowa Concentrated Animal Feeding Operations Air Quality Study
- What are the impacts of CAFOs on worker, environmental and community health?
- Which pollutants from CAFOs should we be concerned about?
- For which of the pollutants has a maximum residue level ( MRL) been set?
- Do pollutants from CAFOs affect the workers and those in the surrounding community differently? If so, why?
- Which federal agencies are concerned with regulating pollution from CAFOs?
- What are the policy options suggested by the authors for regulating and mitigating pollutants from CAFOs?
- At what source points do the authors suggest that pollutants from CAFOs be measured?
- What is the significance of additive effects for setting up tolerance levels?
- What is a manure management plan?
- Does the Occupational Safety and Health Administration ( OSHA) have standards to protect CAFO workers from pollutants?
- Are all CAFOs regulated by OSHA?
- What is the difference between vertical integration and vertical coordination?
- What is the potential of the suggested vertical coordination in reducing the adverse impacts of CAFOs?

- How have veterinarians and producer groups responded to the public’s concern over subtherapeutic antibiotic use in animal production?
- Why do conflicting projections regarding the extent of antibiotic usage for subtherapeutic purposes exist? How can this problem be overcome?
- How are some of the European countries, like Denmark and Sweden, managing the problem of subtherapeutic usage of antibiotics? What do their experiences reveal?
- What are the implications of banning subtherapeutic usage of antibiotics?
- What are the alternatives that can be tried instead of subtherapeutic usage of antibiotics?
