    • "The most common factors contributing to insecticide exposure from foggers include inability or failure to vacate before discharge of the fogger, unintentional fogger discharge, premature re-entry, excessive number of foggers, and failure to notify others nearby (Wheeler et al. 2008). In an effort to minimize misuse caused by failure to follow label instructions, EPA has required manufacturers to make a number of labeling changes by 30 September 2011, to enhance clarity and draw increased attention to critical information (http: "

    ABSTRACT: Field-collected bed bugs (Cimex lectularius L.) showed little, if any, adverse effects after 2-h direct exposure to the aerosolized pyrethroid(s) from three over-the-counter total-release foggers ('bug bombs' or 'foggers'); Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger. One field-collected population, EPM, was an exception in that there was significant mortality at 5-7 d when bugs out in the open had been exposed to the Spectracide Fogger; mortality was low when these bugs had access to an optional harborage, a situation observed for all field-collected populations when exposed to the three foggers. Even the Harlan strain, the long-term laboratory population that is susceptible to pyrethroids and that served as an internal control in these experiments, was unaffected if the bugs were covered by a thin cloth layer that provided harborage. In residences and other settings, the majority of bed bugs hide in protected sites where they will not be directly contracted by the insecticide mist from foggers. This study provides the first scientific data supporting the position that total-release foggers should not be recommended for control of bed bugs, because 1) many field-collected bed bugs are resistant to pyrethroids, and they are not affected by brief exposure to low concentrations of pyrethrins and/or pyrethroids provided by foggers; and 2) there is minimal, if any, insecticide penetration into typical bed bug harborage sites. This study provides strong evidence that Hotshot Bedbug and Flea Fogger, Spectracide Bug Stop Indoor Fogger, and Eliminator Indoor Fogger were ineffective as bed bug control agents.

    ABSTRACT: Following the investigation of a birth defects cluster involving migrant farmworkers employed in North Carolina and Florida, it became clear that greater efforts were needed to protect agricultural workers from pesticide exposure. Documentation is drawn from peer-reviewed published articles, government reports and news accounts. The birth defects cluster was identified and investigated by state and federal pesticide poisoning surveillance system staff. Following the investigation, efforts were initiated to highlight pesticides as an important public health issue needing more attention. A series of subsequent events led to the creation and passage of important legislation recently enacted in North Carolina. The legislation resulted in funding to promote various activities to prevent harm from pesticides including strengthening surveillance, improving the quality of pesticide compliance inspections, and increasing and improving pesticide safety training. The legislation also broadened the coverage of anti-retaliation rules to include agricultural workers, and increased recordkeeping requirements pertaining to pesticide applications. The important and positive impacts that can occur through surveillance activities are highlighted. As such, it is important to continue to support and improve occupational illness and injury surveillance programs.

    ABSTRACT: Problem-based learning, which emphasizes group collaboration to solve real-world case scenarios, is an instructional approach that is well suited to occupational and environmental health nursing education. Learners actively work through case studies rather than passively receive information presented through lectures. Problem-based learning methods promote critical thinking skills and motivate learning, preparing learners for professional practice in complex, ever-changing environments. Despite these advantages, problem-based learning is under-utilized in nursing education compared to more traditional lecture methods. This article presents key concepts of problem-based learning, discusses problem-based learning in educating occupational and environmental health nurses, and describes the development of a problem-based learning case aimed at increasing occupational and environmental health nurses capacity to address pesticide exposure among migrant and seasonal agricultural workers.
