Campylobacter, a zoonotic pathogen of global importance: Prevalence and risk factors in the fast-evolving chicken meat system of Nairobi, Kenya por Carron, M., Yu-Mei Chang, Momanyi, Kelvin N., Akoko, James M., Kiiru, J., Bettridge, Judy M., Chaloner, G., Rushton, Jonathan, O'Brien, S., Williams, N., Fèvre, Eric M., Häsler, Barbara

“…Multivariable logistic regression identified the selling of defrosted meat as a retailer risk factor (OR: 4.69; 95% CI: 1.31–19.97), calling for more investigation of the reported repetitive freezing-thawing processes and cold chain improvement options. At the farm-level, having a pen floor of material not easy to clean was found to increase the risk (OR: 2.31; 95%CI: 1.06–5.37). …”

Application of deep tillage and Berken Maresha for hardpan sites to improve infiltration and crop productivity [Abstract only] por Muche, H., Abdela, M., Schmitter, Petra S., Nakawuka, Prossie, Tilahun, Seifu A., Steenhuis, Tammo S., Langan, Simon J.

“…Long term use of Maresha plow, a conventional plow pulled by oxen, has resulted in the formation of a restrictive layer thereby limiting water movement and aeration as well as root zone penetration in the soil profile. Several studies have shown that improved tillage practices can positively affect infiltration and aeration resulting in increased rainwater use efficiency and agricultural production. …”
