Public awareness, risk perceptions and behaviour towards antibiotic use in food-producing animals and antimicrobial resistance in Malaysia: A cross-sectional study

Antimicrobial resistance (AMR) is a growing global public health problem, particularly in low- and middleincome countries, including Malaysia. Understanding risk perceptions on antimicrobial use (AMU) in foodproducing animals from the general public perspective is an essential component in addressing AMR. However, little is known about public risk perceptions of AMU and AMR in food-producing animals in Malaysia. The objectives of this study were to assess the level of awareness, risk perceptions, and behaviour regarding antibiotic use in food-producing animals and antimicrobial resistance and to examine the factors associated with risk perceptions and the relationship between knowledge, awareness, risk perceptions and behaviour among the general public in Malaysia. A cross-sectional survey was used. Both descriptive and analytical statistics were used to analyse data and present results. Correlation and regression analyses were conducted to examine the factors associated with risk perceptions and the relationship between risk perceptions and behaviour. A total of 416 individuals participated in the study. The majority of the participants (69.2 %) had low knowledge of antibiotics and antibiotic use in food-producing animals. The levels of awareness of antibiotic use and the perceived route of antibiotic resistance transfer were moderate. Participants had a high level of general risk perception (GRP) of antibiotic use, a moderate level of personal-level risk perception (PRP) of antibiotic resistance transmission, and a high level of societal-level risk perception (SRP) of antibiotic resistance transmission. Awareness of antibiotic use was a significant predictor of GRP (beta = 0.27, 95 %CI: 0.12-0.31, P < 0.001). Awareness of route of resistance transfer was a significant predictor of PRP (beta = 0.54, 95 %CI: 0.32-0.44, P < 0.001) and SRP (beta = 0.47, 95 %CI: 0.32-0.46, P < 0.001). PRP is the only significant predictor of behavioural changes towards antibiotic use and antibiotic resistance (OR = 1.45 [1.02-2.07], P = 0.041). Overall, there is a general lack of knowledge and little awareness of antibiotic use and antibiotic resistance in food-producing animals in Malaysia. Risk perceptions were moderate to high and were significantly predicted by awareness of antibiotic use and route of resistance transfer. Personal-level risk perception was a significant predictor of behavioural changes aimed at reducing the risk of AMU and AMR. It is imperative to raise public awareness and understanding of the risks associated with AMU in food-producing animals. Risk communication should be emphasised to ensure the translation of public risk perceptions into behavioural changes.
