Biosecurity measures are practices designed to prevent the introduction and spread of harmful organisms, such as pests and diseases, in agriculture and other environments. These measures can include controlling access to farms, using disinfectants, and monitoring animal health to protect crops and livestock. In addition to agriculture, biosecurity is important in areas like public health and environmental conservation. It involves strategies such as vaccination programs, surveillance of wildlife, and regulations on the movement of goods to minimize risks to human health and ecosystems. Effective biosecurity helps ensure food safety and protects biodiversity.
