BACKGROUND The epidemiology of Toxocara infection in humans in Mexico has been poorly explored. There is a lack of information about Toxocara infection in waste pickers. AIMS Determine the seroepidemiology of Toxocara infection in waste pickers. METHODS Through a case control study design, the presence of anti-Toxocara IgG antibodies was determined in 90 waste pickers and 90 age- and gender...

BACKGROUND The epidemiology of Helicobacter pylori (H. pylori) infection in waste pickers had not been previously studied. This study aims to determine the association of H. pylori seropositivity and waste picking activity; and to determine socio-demographic, clinical, work, and behavioral characteristics associated with H. pylori seropositivity in waste pickers. METHODS Through a case-contro...

BACKGROUND Infection with Leptospira may occur by contact with Leptospira-infected animals. Waste pickers are in contact with rodents and dogs while picking in the garbage. Whether waste pickers are at risk for Leptospira infection is largely unknown. This study was aimed to determine the association of Leptospira IgG seroprevalence with the occupation of waste picking, and to determine the epi...

Congestion is a problem in order-picking-systems. We developed CTMC models to represent picker blocking in cases including pickers with different exponentially distributed picking times and k pickers, for narrow and wide aisle systems. The focus was not to produce an all-inclusive model, but to generate models that give designers insight of the system, allowing them to reduce the number of vari...

OBJECTIVE To present the pitiable working conditions of clinical waste pickers in hospitals in the Northwest region of Cameroon and associated exposure to health hazards. METHODS Observe clinical waste pickers as they carry out their functions for three days and carry out informal consultations (discussion) with the waste pickers on their working conditions, possible health risks and avenues ...

Helping to eliminate poverty and achieve sustainable development through public-private partnerships in infrastructure noTE no. 44 – oCT 2008 F or the urban poor in developing countries, informal waste recycling is a common way to earn income. There are few reliable estimates of the number of people engaged in waste picking or of its economic and environmental impact. Yet studies suggest that w...

Batching orders and routing order pickers is a commonly studied problem in many picker-to-parts warehouses. The impact of individual differences in picking skills on performance has received little attention. In this paper, we show that taking into account differences in the skills of individual pickers when assigning work has a substantial effect on total batch execution time and picker produc...

Management of burgeoning solid wastes has become a critical issue for almost all the major cities in India. Although the responsibility of solid waste management remains primarily with the municipal bodies, several other stakeholder groups play significant roles in the process. In the Indian scenario the so-called waste pickers, who come from highly vulnerable social backgrounds, play a unique ...

BACKGROUND The occupation of waste-picking characterised as 3Ds - dangerous, drudgery and demanding. In this context, the study aimed to assess occupational morbidities among the waste-pickers and attempts to identify potential individual level risk factors enhancing health risks. Additionally, economic burden of morbidities has been assessed. METHODS The burden of the morbidities was assesse...

BACKGROUND Farm workers and female cotton pickers are exposed to residual impacts of pesticide use in cotton production, in addition to dust, ultraviolet radiation, etc. Cotton picking causes various health hazards among cotton pickers with varied health cost. A soil bacterium known as Bacillus thuringiensis (Bt) is incorporated in cotton seed through genetic modification and it has resistance ...
