Summary
This summary is machine-generated.Coxiella burnetii, the cause of Q fever, was detected in 18.8% of dairy products in Kwara State, Nigeria. This highlights a significant risk for milk-borne zoonotic disease transmission to consumers.
Area Of Science
- Veterinary Microbiology
- Food Safety
- Zoonotic Diseases
Background
- Coxiella burnetii is the causative agent of Q fever, a zoonotic disease of growing public health significance.
- Q fever causes substantial economic losses in livestock farming.
- Contaminated dairy products present a direct threat to human consumers.
Purpose Of The Study
- To determine the prevalence of Coxiella burnetii in dairy products within Kwara State, Nigeria.
- To assess the risk of zoonotic disease transmission through the dairy value chain in the region.
Main Methods
- A cross-sectional study was conducted on 51 traditional Fulani transhumance farms.
- A total of 204 pooled raw milk samples and 18 cheese samples were collected.
- Real-time PCR targeting the IS1111 element was used for pathogen detection.
Main Results
- The overall apparent prevalence of Coxiella burnetii in milk and cheese was 18.8%.
- Cheese samples showed a higher positivity rate (22.2%) compared to raw milk (17.6%).
- Prevalence varied significantly across different local government areas, with Moro LGA showing higher rates.
Conclusions
- The presence of Coxiella burnetii in dairy products poses a direct risk of milk-borne zoonotic disease transmission.
- Public education on dairy product safety and consumption of unpasteurized milk is crucial.
- Further molecular studies are needed to characterize Coxiella burnetii genotypes in Nigeria.
