Points described here are useful in designing a biosecurity program against E.coli
- E.coli does not possess any unique resistance capability
- Susceptible to physical and chemical agents like other vegetative gram-negative bacteria
- It can be killed at 60 degree Celsius for 30 minutes or 70-degree Celsius for 2 minutes
- Thermal fogging can inactivate it (90% reduction in the litter)
- It does not affect by cold or freeze
- Do not divide at pH below 4.5 or more than 9 BUT NOT KILLED
- Some virulent strains (e.g., O157:H7) are acid tolerant, which permits them to pass through the stomach without being killed.
- Organic acids are more effective than inorganic acids at inhibiting growth. Treatment with citric, tartaric, or salicylic acids significantly reduce coliform counts in poultry litter
- Stabilized chlorine dioxide is highly effective when used as a water disinfectant
- UV disinfection of water is a low-cost method of treating drinking water
