Abstract

Samples of dry‐roasted groundnuts purchased from street hawkers, markets and retail shops in southwestern Nigeria were analysed for moisture content, fungal populations and aflatoxin contamination. The moisture content varied from 2.1 to 3.6 per cent, while the mould counts using the dilution plating method ranged from 2.9 × 102 to 6.3 × 102 colony‐forming units per gram in samples. Aflatoxin B1 was found in 64.2 per cent of samples with a mean of 25.5 ppb. Aflatoxins B2, G1 and G2 were detected in 26.4, 11.3 and 2.8 per cent of the samples with mean levels of 10.7, 7.2 and 8 ppb respectively in contaminated samples. It is concluded that the regular consumption of DRG by Nigerians might present potential health hazards.

Abstract

This chapter draws on experiences of research with children who work as street traders in Nigeria, with a focus on establishing trust and the related concepts of power and rights. The discussion stems from a study which used a rights-based approach to gather children’s accounts of their experiences of working as street traders within a large market in a Nigerian city. Seventeen children (aged 10–15 years) took part in semi-structured interviews and focus groups. Children talked about difficult situations as they undertook tiring work and received conflicting messages about the importance of making an economic contribution to the family, versus the need to attend school. Researching these accounts entailed a number of ethical challenges, which centred on access and recruitment; consent/assent and participation; sensitivity of research; and researcher positionality. First, recruitment was limited to children with parents/guardians who could give consent, with assent from the children. Second, a relationship of trust had to be negotiated between the researcher and the participating children. This involved acknowledging different elements of adult–child positionality, which had implications for the ways in which children participated in the study. Third, sensitivity was essential given that children could discuss attitudes or activities, which were not universally seen as acceptable. Fourth, researcher positionality influenced all aspects of the study, including access to children, how relationships were forged and the interpretation of data. All of these challenges relied heavily on building trust with children. However, the authors illustrate how trust must be employed cautiously in research with children, given adult–child power disparities.
