The phages Escos1 and Escog1 were isolated from sewage and garden soil samples respectively and characterized for morphology, genome size and sensitivity to pH, temperature and chloroform. Carrot slices of uniform surface area were sterilized by exposure to a radiation dose of 6 kGy. One set of these sterile slices was spiked with Escherichia coli (E. coli) DH5-α (8-log₁₀ Colony Forming Units (CFUs) ml⁻¹). The spiked slices were dried and treated with a high titre (10¹⁰ Plaque Forming Units (PFUs) ml⁻¹) cocktail of Escos1 and Escog1. The slices were  then incubated at room temperature (R.T.) and checked for reduction in bacterial CFUs over 6 days, in comparison with a control. Another set of sterile slices was pre-treated with the cocktail and dried. This was followed by artificial E. coli contamination of pre-treated slices on consecutive days. The surviving CFUs were determined to study the prophylactic potential of the phage cocktail. An average of 6.23-log₁₀ reduction in E. coli CFUs per carrot slice was obtained in the post-contamination treatments studies. Pre-contamination treatment reduced the bacterial load by an average of 6.22-log₁₀ CFUs per slice. More than 99.99% of the phages used for the treatment could be removed with gentle rinsing.
