Mycotoxins are metabolites produced by phytopathogenic and spoilage fungi in animal feed as a result of poor storage. The mycotoxins can also originate the field excreted milk when dairy animals consume such feeds, posing public health risk concern. aim this study was to conduct assessment informal sub-value chains rural peri-urban systems Nakuru County, determining prevalence quantity levels feeds milk. A total 74 samples 120 were simultaneously collected from individual cows actors value...
Antibiotic residues are drug substances found in food from plants or animals initially exposed to antibiotics. In animal husbandry antibiotics have widely been used for the treatment of diseases. These ability expose public serious health hazards. Kenya not only related lack withdrawal periods but also intentional addition extend milk's shelf life. The aim this study was investigate occurrence 13 veterinary drugs tetracyclines and sulphonamides along dairy sub value chain. carried out Nakuru...
Processing mango (Mangifera indica L.) is one of the ways minimizing post-harvest losses. Lactic acid bacteria (LAB) fermentation a promising processing method to expand diversity processed products. The aim this study was develop fermented leathers and evaluate effect LAB pulp on physicochemical, antioxidant, sensory properties leathers. Pulps two varieties (apple ngowe) were at 37 °C for 24, 48, 72 h using strains; Lactobacillus plantarum (DCRUST PKLP4) casei (LC-1) its physicochemical...
ABSTRACT Post‐harvest fish losses (PHFL) significantly impact the aquaculture sector in Kenya, undermining food security and economic growth. This study investigated socio‐demographic factors handling practices influencing PHFL Kakamega County's cultured tilapia value chain. Data were collected from 94 chain actors operating across multiple nodes, including farming, processing retail stages six sub‐counties using surveys observations. Results revealed that 64% of participants female, 40.3%...
In Kenya, the extensive use of agrochemicals in potato farming raises concerns about pesticide residues tubers and products. This study aimed to document application practices farmers Nyandarua County, Kenya evaluate effect on levels raw tubers. Also, evaluated various heat processing methods residue potatoes. A cross-sectional survey using semi-structured questionnaires was conducted 275 randomly selected farmers. Alongside, Shangi variety samples (n=16) from respective were analyzed for...
This study aimed to determine the effect of fermentation using an isolated Levilactobacillus brevis strain on antinutrients and protein quality cassava leaves. Cassava leaves from tajirika kibandameno variety which are considered bitter sweet varieties, respectively, were fermented probiotic isolate spontaneous was used as a control. The interest cyanide phytic acid whereas analyzed in terms total crude in-vitro digestibility. These standard procedures namely; picrate paper method for...
The aim of this study was to assess the probiotic potential and safety profile a Lactiplantibacillus plantarum EGER41 strain isolated from Kenyan spontaneously fermented milk, Amabere amaruranu. L. isolate tested for temperature sensitivity (at 15 °C, 30 37 45 °C), pH tolerance 2.0, 2.5, 3.0, 3.5, 6.5 as control), 0.4% phenol observe its survival in gastrointestinal tract humans. For evaluation isolate, antagonistic activity against pathogenic strains Staphylococcus aureus, Escherichia coli,...
Objective To assess, within communities experiencing Ebola virus outbreaks, the risks associated with disposal of human waste and to generate recommendations for mitigating such risks.Methods A team expertise in Hazard Analysis Critical Control Points framework identified products from care individuals disease constructed, tested confirmed flow diagrams showing creation products.After listing potential hazards each step diagram, conducted a hazard analysis, determined critical control points...
On-farm hygienic practices are important in assuring quality and safety of milk for consumers reducing losses at production post-harvest. This study investigated the relationship between milking practices, mastitis as well somatic cell counts (SCC) effects high SCC on post-harvest (PHL) smallholder dairy (n = 64) pastoral camel 15) herds Kenya. The collected data included test udder quarters 1236) collection samples laboratory analyses: SCC, detection Staphylococcus aureus Streptococcus...
Suusa is a spontaneously fermented milk product from raw camel used by the pastoral communities of Northern and Eastern Kenya. The can be as result intentional fermentation at ambient temperature for 3 days where it prepared women specifically home consumption. also unintentional intended sale, undergoes coagulation any node informal value chain. Since no heat treatment involved in preparation, microbial safety quality suusa completely dependent on inherent flora handling practices....
Pastoral communities in Kenya have used smoke from specific herbs as a technique of disinfecting milk-handling containers, preserving milk and to impart characteristic desired flavour raw camel milk. The smoking is expected extend the shelf life milk, despite high environmental temperatures (>28 °C). aim this study was determine antimicrobial effect on plastic container surfaces efficacy preservation method. Smoked containers (n = 25) were conveniently collected pastoral community households...
The camel milk chain was investigated for microbial quality and safety its implications to public health. At production, 66% of the samples had load less than 105 cfu/ml compared 54% at bulking marketing where over 106 colony forming units (cfu)/ml. Gram-positive cocci (42%) were majority production. Gram-negative rods formed (54%) marketing. Salmonella spp. detected production levels. There slow rate in acid development decreasing total viable count market level by 29% 5 h. Key...
Abstract Background Undernutrition accounts for nearly half of under-five child mortality in developing countries where household nutrition is largely dependent on agriculture. Despite the strong influence agroecology agriculture those countries, limited information exists whether undernutrition children under five varies with agro-ecological location. Methods Using Karamoja sub-region Uganda, one most food insecure parts Eastern Africa as a case area, and applying multi-stage sampling...
The aim of this study was to map the camel milk value chain and establish predisposing factors for increase in microbial counts along chain. Isiolo County chosen study. Data collection done through key informant interviews, structured interview schedules, observation analysis samples. During sampling, temperature, environmental time volume from which sample taken were recorded. Along chain, increased significantly log10 4.91 ± 1.04 CFU/ml at production 7.52 1.32 Nairobi market total viable...
Commercial fermented milks have health benefit potential attributed to pure probiotics used as starter culture. Lactic acid bacteria (LABs) are the and promote stabilization of gastrointestinal microecology humans by producing secondary metabolites like lactic, acetic propionic acid, hydrogen peroxide bacteriocins (bactericidal proteins produced lactic bacteria). These benefiting. Mursik, an indigenous milk product is consumed at households many Kenyan communities, for example Kalenjin. The...
The effect of a targeted training intervention on uptake recommended hygiene practices by caregivers children 6–23 months was assessed. A sub-sample 40 mothers from 303 households used for detailed study during preparation complementary foods after training. Mothers and were observed 6 evaluated using questionnaire. Data analyzed SPSS Chi-square test to determine the differences in proportions who adopted practices. Results showed significant increase followed There decrease prevalence...
The demand for Ready-To-Eat (RTE) meat products is rising especially to the busy urban dwellers. Handling, processing, and selling methods of RTE contaminate them with pathogens. However, there lack evidence risk antimicrobial resistance (AMR) In this study, 105 were sampled across Nakuru County assessed Escherichia coli load, (AMR), presence AMR genes. All contaminated coliforms E. but levels differed significantly (p<0.05) location sample collection type RTE. Antimicrobial susceptibility...
