BACKGROUND
The widespread indiscriminate application of antibiotics to food crops to control plant disease represents a potential human health risk. In this study, the presence of antibiotic-resistant staphylococci associated with workers and orange orchard environments was determined. A total of 20 orchards (orange and other fruits) were enrolled in the study. Trees in the orange orchards were treated with ampicillin on a pre-determined schedule. Environmental samples (n = 60) included soil, water, and oranges; 152 hand and nasal samples were collected from 76 healthy workers. Antibiotic susceptibility profiles were determined for all staphylococcal isolates.
RESULTS
This investigation revealed that of the total spp. recovered from the orange orchard, 30% (3/10) were resistant to erythromycin, 20% (2/10) were resistant to ampicillin, and 20% (2/10) resistant to both erythromycin and ampicillin.
CONCLUSION
The application of antibiotics to orange trees in open production environments to halt the spread of bacterial disease presents risks to the environment and creates health concerns for Thai farmers using those agents. ARB on crops such as oranges may enter the global food supply and adversely affect public health.
背景
广泛、无差别地将抗生素应用于农作物以控制植物病害，这对人类健康构成了潜在威胁。本研究旨在确定与工人和橘园环境相关的耐抗生素葡萄球菌的存在情况。共有 20 个果园（包括橘园和其他果园）参与了此项研究。橘园中，按照预定计划定期使用氨苄青霉素处理橘树。共采集了 60 份环境样本（土壤、水和橘子），并从 76 名健康工人中采集了 152 份手部和鼻腔样本。对所有葡萄球菌分离株进行了抗生素药敏性分析。
结果
本研究发现，从橘园中总共分离出的 10 株 spp.中，有 30%（3/10）对红霉素耐药，20%（2/10）对氨苄青霉素耐药，20%（2/10）对红霉素和氨苄青霉素均耐药。
结论
在开放式生产环境中，将抗生素应用于橘树以阻止细菌病害的传播，这不仅对环境构成了风险，而且也使使用这些药剂的泰国农民产生了健康隐忧。此类抗生素在作物（如橘子）上的使用，可能会进入全球食品供应，并对公众健康产生不利影响。
