Policy briefAfrica Sustainable Livestock 2050: Presence and biosecurity practices of youth in poultry value chains
Evidence from urban and peri-urban subregions of Kenya and Uganda
2022Also available in:
No results found.This brief explores the presence and characteristics of youth working in the poultry sector through data collected in two urban and peri-urban subregions in Kenya and Uganda. Youth empowerment and employment have gained prominence in national and international policy agenda. The growing livestock sector has great potential to provide employment opportunities, but available evidence suggests that there is limited interest among young people in engaging in livestock activities. The sample includes mainly small and mid-size business-oriented entrepreneurs and not subsistence-oriented backyard poultry keepers. The data shows that the presence of youth involved in the poultry value chain with respect to their share in the total working age population is 16 to 32 percentage points lower in Kenya and 5 to 27 percentage points lower in Uganda. The share of young people is particularly low among producers, which may be due to high initial investment requirements. The average number of birds raised per year is lower among the age groups under 40 in Kenya, while differences in size of business are smaller in Uganda. The share of women is lower among young people along the entire value chain, which may be due to them being occupied with raising children and the lack of backyard poultry keepers in the sample. At the marketing node, considerably more young people have fixed stalls and use plastic or metal cages than their older colleagues. The data presented is on predominantly urban and peri-urban areas and the presence of youth would be probably lower in rural areas. -
ArticleRegional Sub-Saharan Africa Total Diet Study in Benin, Cameroon, Mali and Nigeria Reveals the Presence of 164 Mycotoxins and Other Secondary Metabolites in Foods 2019
Also available in:
No results found.In the framework of the first multi-centre Sub-Saharan Africa Total Diet Study (SSA-TDS), 2328 commonly consumed foods were purchased, prepared as consumed and pooled into 194 composite samples of cereals, tubers, legumes, vegetables, nuts and seeds, dairy, oils, beverages and miscellaneous. Those core foods were tested for mycotoxins and other fungal, bacterial and plant secondary metabolites by liquid chromatography, coupled with tandem mass spectrometry. The highest aflatoxin concentrations were quantified in peanuts, peanut oil and maize. The mean concentration of the sum of aflatoxins AFB1, AFB2, AFG1 and AFG2 (AFtot) in peanut samples (56.4 µg/kg) exceeded EU (4 µg/kg) and Codex (15 µg/kg) standards. The AFtot concentration (max: 246.0 µg/kg) was associated with seasonal and geographic patterns and comprised, on average, 80% AFB1, the most potent aflatoxin. Although ochratoxin A concentrations rarely exceeded existing Codex standards, it was detected in unregulated foods. One palm oil composite sample contained 98 different metabolites, including 35.4 µg/kg of ochratoxin A. In total, 164 different metabolites were detected, with unspecific metabolites like asperglaucide, cyclo(L-pro-L-val), cyclo (L-pro-L-tyr), flavoglaucin, emodin and tryptophol occurring in more than 50% of composite samples. Aflatoxin B1 (AFB1), fumonisin B1 (FB1), sterigmatocystin (STC), ochratoxin A (OTA), citrinin (CIT) and many other secondary fungal metabolites are frequent co-contaminants in staple foods, such as maize and sorghum. Populations from North Cameroon and from Benin may, therefore, suffer chronic and simultaneous exposure to AFB1, FB1, STC, OTA and CIT, which are prevalent in their diet.
