BACKGROUND: Antibacterial drug use in food producing animals, in addition to the very beneficial effects on the prevention, treatment, and control of infectious diseases, can lead to health risks including microbial resistance and drug residues. This survey was conducted due to the lack of information on the status of antibacterial drug use in dairy farms of Qom province. OBJECTIVES: To study the usage pattern of antibacterial drugs and compliance with public health- related measures in dairy cattle farms in Qom province. METHODS: In this study, 100 dairy herds were surveyed in three areas of Qom province including the southern part (Kahak), West (Jafar-abad and Khalajestan) and central part (Qom and the suburbs) using a questionnaire and direct interview. RESULTS: Injectable oxytetracycline, tylosin, penicillin + streptomycin were the most frequently used antibacterial products in dairy farms of Qom province (94%, 89% and 87%, respectively). A range of other antibacterial drugs showed high percentages of usage, as well. Among the 9 intramammary products, Tetranebalon®/Mastijet Forte® and Linconeocin MC® with 50% and 40% of frequency were the most commonly used products. Also, in a significant percentage of dairy farms, the milk collected from livestock treated with antibacterial drugs for mastitis (35%) or other illnesses (41%) was introduced into the milk reservoirs to be used in humans. CONCLUSIONS: In Qom province, there was an overuse of antibacterial drugs and high percentage of dairy farm units that did not follow the principles of rational drug therapy and the withdrawal times of milk and meat. This could be due to inadequate awareness of livestock workers regarding the public health implications of using these drugs and insufficient monitoring of veterinary authority in the province.
