The challenge of antimicrobial resistance (AMR) is grave in developing countries. Antimicrobials are misused yet stakeholders’ contribution to antimicrobial stewardship is low. Veterinary students are future prescribers and their knowledge could influence progress in combating AMR; hence, there is a need to assess their knowledge, attitude, and awareness of AMR. A multi-institutional questionnaire was administered to undergraduates in Nigerian veterinary schools. It comprised demographics, own personal antibiotic usage, and knowledge, attitude, and awareness of AMR in humans and animals. Descriptive statistics and logistic regression were used for analyses. Of the 426 respondents, 39.2% reported personal antimicrobial use in the previous six months. Over 60% received knowledge scores lower than average and >87% requested more education on clinical use and prescriptions pre-graduation, monitored dispensing of antimicrobials, conducting AMR research, and confirmed link among human, animal, and environmental health. Less than 25% of respondents were aware of antimicrobial stewardship and global efforts/organizations for AMR. Final year students have 9-fold and 14-fold more satisfactory knowledge on antimicrobials in humans and animals compared with other students, respectively (p = 0.001). Final year students also have more knowledge (13×) and awareness of contributory factors (3×) on AMR (p = 0.001) than other students. Unsatisfactory knowledge on AMR issues exists among veterinary students yet willingness to improve was observed. Identified knowledge, attitude, and gaps in AMR awareness should be targeted by veterinary schools in Nigeria.
BackgroundAntimicrobials are used as a measure to maintain good health and productivity of lactating cows. This study assessed pastoralists’ knowledge and practices regarding AMU in lactating cows; and risk pathways for AMR dissemination from cow milk to humans.MethodsInterview questionnaire-based cross-sectional study was conducted in Fulani pastoral communities. Frequencies and proportions were used for descriptive statistics. Chi-square test and multivariable logistic regressions were used for analytic statistics at 95% confidence level.ResultsAll recruited 384 pastoral households participated. About 11% of participants indicated antimicrobials misuse as when given at under-dose, while 58.9% had no knowledge of what antimicrobial misuse entailed. Most participants (51.6%) were unaware about effects of improper AMU. Most respondents (61.7%) reported self-prescription of antimicrobials used on cows. Also, 67.4% of respondents reported arbitrary applications of antimicrobials used in cows, while 15% used antimicrobials to increase milk yield. Frequently used antimicrobials were: tetracycline (98.7%), penicillin (96.6%), streptomycin (95.8%) and sulfonamides (95.3%). Consumption of raw milk and milk products (p = 0.010); contacts with contaminated udder (p = 0.002); and aerosols of discarded contaminated milk P = 0.001) were perceived risk pathways for spread of antimicrobial resistance from cow milk. Improper AMU (p<0.001), non-enforcement of regulating laws (p<0.001), weak financial status (p<0.001), and low education and expertise (p<0.001) influenced antimicrobials misuse in lactating cows.ConclusionsThis study highlighted low levels of knowledge, risk perceptions and practices regarding AMU and AMR among survey pastoralists. This calls for education of the vulnerable populations on promotion of prudent AMU in lactating cows through ‘One Health’ approach, to assure food safety, food security, and public and environmental health.
Background Rift Valley fever (RVF) is a vector-borne emerging zoonotic disease of animals and humans, characterized by socioeconomic losses to livestock farmers and global public health threat. The study determined RVFV seroprevalence in cattle, assessed pastoralists’ knowledge about RVF, and factors that influence its occurrence in pastoral cattle herds of Nigeria. A cross-sectional study was conducted in pastoral herds of North-central Nigeria from 2017 to 2018. Data were collected using serology and questionnaire tools. Descriptive statistics were used to analyze the obtained data. Categorical variables were presented as proportions and their associations determined by Chi-square tests. Associations of risk factors were analyzed by univariable and multivariable logistic regressions analyses at 95% confidence level. Results The overall IgM seropositivity of RVFV in pastoral cattle herds was 5.6%. This was higher in nomadic herds (7.4%) than in agro-pastoral herds (3.8%). All animal demographic characteristics of age, sex and breeds were not significantly ( p > 0.05) associated with RVFV occurrence in pastoral herds. All the 403 pastoralists selected participated in the study, with the majorities of them being male, married and have no formal education. Majority of the pastoralists had low knowledge levels about zoonotic RVFV infection. All identified socio-ecological factors significantly ( p < 0.05) influenced RVFV occurrence in herds. Mosquitoes availability in cattle environment (OR = 7.81; 95% CI: 4.85, 12.37), presence of rivers and streams at grazing fields (OR = 10.80; 95% CI: 6.77, 17.34), high rainfall (OR = 4.30; 95% CI: 2.74, 6.59), irrigated rice fields (OR = 5.14; 95% CI: 3.21, 7.79) , bushy vegetation (OR = 6.11; 95% CI: 3.96, 9.43), animal movement (OR = 2.2; 95% CI: 1.45, 3.25), and seasons (OR = 2.34; 95% CI: 1.55, 3.51) were more likely to influenced RVFV occurrence in cattle herds. Conclusions Results of this study had illustrated recent circulation of RVFV in pastoral cattle herds in Nigeria and needs urgent interventions. The surveyed pastoralists had low knowledge level about RVF while the socio-ecological factors significantly influenced RVFV occurrence in herds. To address these gaps, pastoralists should be educated on clinical manifestations and modes of transmission of the disease in animals and humans, and mitigation measures. Adequate knowledge about RVF epidemiology will assure food security and public health.
Consumers' perception of food safety risk could influence their food consumption habits. This questionnaire-based (n = 327) cross-sectional study assessed consumers' attitudes about and perception of retail meat risk. Also, the hygiene of meat display tables (n = 105) and retail meat (n = 107) sold to consumers was determined using total aerobic plate count and total coliform count.Most respondents were single (82.6%) and had tertiary educational status (89.3%). Most of the respondents preferred beef (60.9%) over other meat types and made purchases from retailers (71.3%). Overall, the risk perception score on retail meat safety reported by respondents was above average (56%, n = 83), although consumers (53.8%, n = 176) declared that meat consumption is worth the risk. Meat source (χ 2 = 16.65, P = 0.034) and processed meat products (χ 2 = 28.22, P = 0.005) were associated with food safety risk.Respondents opined that meat processors (weighted mean = 3.85%) could influence food safety. The freshness of meat (weighted mean = 2.54%) was the main criterion used by consumers to determine retail meat safety.Sampled meat and meat display tables had high total aerobic counts (>8 log) and total coliform counts (>5 log).These results are indicators of consumers' risk perception and preferences; the observed microbial loads highlight the need for improved hygiene practices associated with meat sold to consumers in Nigeria.
