Viral Diseases of Poultry
- Statement (I) is True: Low-level chemical disinfectants (e.g., standard quaternary ammonium compounds) kill most vegetative bacteria, lipid-enveloped viruses, and some fungi, but fail against bacterial endospores and non-enveloped viruses.
- Statement (II) is False: For industrial poultry biosecurity and sanitation, chemical disinfectants should have a rapid kill time (minimum necessary contact time) so that disinfection is accomplished quickly without requiring hours of surface wetness.
- Conclusion: Statement (I) is true, but Statement (II) is false.
Correct option: (3) Statement (I) is true but Statement (II) is false.
