ViParc

New study on quality and labelling of antimicrobial products

ViParc researchers have recently published a study on the quality and labelling of antimicrobials used in chicken farming in the Mekong Delta of Vietnam. The study, lead by laboratory scientist Ms. Yen Nguyen Thi Phuong, tested the 20 most used antimicrobial products among a large cohort of chicken farmers that had previously been enrolled in the ViParc project (www.viparc.org). Three different batches of each different product purchased from different sources were investigated for the strength of antimicrobial active ỉngredient (AAI) declared in the label using liquid chromatography-mass spectrometry. Only 28.8% batches contained all AAIs within 10% of the declared strength. Guidelines for 65% of these products explicitly advised on prophylactic use (i.e. to prevent disease). Withdrawal times for both egg and meat production was only provided for 4/20 (20%) products. These guidelines undermine efforts to reduce prophylactic use of antimicrobials. Given the importance that farmers give to the guidelines provided in antimicrobial products, and given that often reliable advice on antimicrobial use is not available for many small-scale farmers, we recommend that authorities should take appropriate steps to ensure quality and improve the labelling of antimicrobial products.
