New Study Highlights Levels of Antimicrobial Usage in Chicken Flocks in the Mekong Delta

A recent published article in Frontiers in Veterinary Science of ViParc highlights the magnitude of antimicrobial use in chicken production in the Mekong Delta of Vietnam. The study, led by Nguyen Van Cuong (ViParc study co-ordinator), described all antimicrobials used and quantified their antimicrobial active ingredient content using different metrics. It was based on a sample of 102 small-scale chicken farms and 203 full production cycles, was carried out between October 2016 and May 2018. The study identified 236 different antimicrobial-containing products used by farmers on their flocks. In terms of doses, up to sixty percent of total usage were given in the early stage (‘brooding’), when chickens are small. Three out of four antimicrobial products contained active ingredients (i.e. colistin, quinolones, macrolides…) that are of ‘critical importance’ according to the World Health Organization. Worryingly, 16 of the products used were intended for human medicine. On average, chickens consumed 791.8 mg/kg of chicken at treatment, 323.4 mg/kg of chicken sold, and the treatment incident was 382.6 per 1,000 days. These results suggest that AMU reduction efforts should preferentially target the early (brooding) period, whilst restricting access to antimicrobials of critical importance for human medicine.
