**5. Conclusions and prospects**

Without any doubt, environmental monitoring and food safety are the main universal worries that we humans have to oppose and are constantly struggling to take them over. In this chapter, we evidently demonstrated the applications of reported promising platforms of phage-based sensors in the screening of food- and environment-related contaminants. We reviewed demonstrative phage/phage components applied in sensors' development for diagnosis of food pollutants specifically comprising pathogens and toxins. By collaboration with engineers and scientists from multidisciplinary area to design a field applicable sensor and make advancements in phage-based sensors for food safety and environmental monitoring, we expect that this chapter might bring together the technologies related to application of phage-based sensors, in food and environmental safety, and infectious disease
