Evaluation Of Smoked Fish Market Trends In The City Of Ngaoundere (Adamawa-Cameroon)

This study was conducted to evaluate the market trends of smoked fish in the city of Ngaoundere (Adamawa-Cameroon). A questionnaire survey was conducted among 37 smoked fish retailers in 2 subdivisions of Ngaoundere. The data collected were analysed and processed using Excel software 2016. The results showed that in the Ngaoundere I and II subdivisions, consumers of smoked fish experience scarcity during certain periods of the year and this is related to the biological cycle of the fish. Also, smoked fish is sold mainly by men (89.19%), young people aged between 20 and 40 years (83.79%). The ethnic group most represented in the sector is Mousgoum (72.97%). The main source of supply for retailers is Lagdo (54.05%). Only 10.81% of retailers obtain their supplies locally, so that 89.19% of fish sold in Ngaoundere town comes from elsewhere (Lagdo, Tibati, Lom pangar, Maga, etc.). Tilapia is the most popular species (51.35%) because of its organoleptic properties and accessibility. The average daily income of a trader is less than 15,000 FCFA (56.76%). Smoked fish is subject to attacks by pests, which are mainly insect pests (76%). The most common means of combating pests are heating with wood fires (48.65%) and the use of insecticides (24.32%). Retailers (100%) face several institutional, financial, economic and commercial constraints in carrying out their activity which if adequately addressed can help better organise the sector for the protection of stakeholders

Technico-Economical Diagnosis of Traditional Goats Farms Based on Zootechnical Performances in the Locality of Wakwa (Adamawa Region-Cameroon)

A survey was carried out in the locality of Wakwa, region of Adamawa-Cameroon during the month of April 2021. The purpose of this study was to determine the elements of calculation of the gross product, intermediate consumption, and the method of calculation of the added value of traditional farms in the area with the zootechnical parameters of the goat as elements of economic production through the administration of a previously established questionnaire. The questions asked concerned: the socio-economic profile of the breeders, the farming or breeding system practiced the zootechnical parameters and the price and cost elements of inputs. It was noticed from this survey that the gender profile of the farmers is made up mostly of men (80%), most of who were above twenty years (92%), with agriculture (56%) as principal activity, trade (20%), handicrafts, pottery, sewing and other side activities (24%). They were mostly persons having received no formal education (68%). Regarding zootechnical parameters, the size of the herd did not exceed 10 animals for the majority of farms (76%). The selling price of the animals varied between 15,000 FCFA and 60,000 FCFA. The Litter of birth goat obeyed the principle of twinning with less than two litters per year or five cubs for a goat. The mortality of neonates and kids was less than 30%, which brings the number of adult goats to between 3 and 4 per year. Grosso modo, the goat breeding activity provides breeders with an estimated annual income of around 64,251.709 CFA, with a total cost of intermediate consumption over the mother's career of 7,904.9922 FCFA for a Gross Added Value of a mother over the duration of her career estimated at 143,300.698 FCFA

Seroprevalence and risk factors of brucellosis among slaughtered indigenous cattle, abattoir personnel and pregnant women in Ngaoundéré, Cameroon

Abstract Background Brucellosis is a neglected debilitating zoonosis with a high prevalence in many developing countries. Bovine brucellosis is widespread in Cameroon but the epidemiological situation of human brucellosis is not known. A cross sectional study was carried to determine the seroprevalence and factors associated with bovine and human Brucellosis among abattoir personnel and pregnant women in Ngaoundéré, Cameroon. Methods Serum sample from 590 abattoir cattle and 816 plausible occupational risk and vulnerable humans to brucellosis (107 abattoir personnel and 709 pregnant women) were collected and screened for anti-brucella antibodies using Rose Bengal Plate Test (RBPT) and ELISA tests. Structured questionnaires were used to collect data on socio-demographics and risk-factors. The differences in proportions between seropositive and seronegative reactors were tested using odds-ratio and χ2tests. Results Bovine brucellosis seroprevalence was at 3.40% (n = 590; 3.4% for RBPT, 5.93% for i-ELISA). Human Brucella seroprevalence was at 5.6% among abattoir personnel (n = 107; 5.6% for RBPT, 12.15% for Brucella IgG ELISA) and 0.28% in pregnant women (n = 709; both tests). Breed (P  200 U/ml) and clinical data for Brucella IgG ELISA seropositive humans. Several potential factors were associated (P > 0.05) with increased risk of human brucellosis seroprevalence among the abattoir personnel. The abattoir personnel were essentially males; the seropositive respondents were male and did not use protective equipment at work. Handling of foetus and uterine contents (OR = 13.00, 95%CI: 1.51–111.88) was associated with increased risk of human brucellosis. Conclusions Antibrucella antibodies are prevalent in cattle (3.40%), among abattoir personnel (5.60%) and in pregnant women (0.28%) in Ngaoundéré, Cameroon. The study reports the first evidence of human brucellosis in Cameroon and therefore, an indication of a real public health problem. Public awareness campaigns and health education especially among livestock professional and in agropastoral communities should be highlighted to disseminate knowledge, associated risk factors and control measures of brucellosis
