High Pathogenic Avian Influenza (HPAI) may pose a major threat for the Belgium poultry sector, as an outbreak of HPAI results in tremendous economic losses. In order to reduce the economic damage for an outbreak, different strategies to control HPAI are evaluated. In a first stage the structure of the Belgium poultry sector is described and risks are analyzed. The actual risks are dependent of the intensive character of poultry farming in Belgium, the large number of transport movements of living poultry, the presence of sensitive nature areas and the border with the Netherlands where the poultry density is even larger. In a second stage the possible intervention strategies are evaluated. Starting from the current regulation, two strategies are worked out: stamping out and emergency vaccination. The success of emergency vaccination is associated with the correct identification of compartments at risk, prompt deployment of emergency vaccines, rapid enforcement of appropriate complementary control measures and also the level of being ready. In a third stage an economic analysis of control strategies for HPAI outbreaks is made. Results suggest that from an economic point of view, stamping-out is at farm level a better option then emergency vaccination within the current context.

ABSTRACTHatchery waste, an animal by-product of the poultry industry, needs sanitation treatment before further use as fertilizer or as a substrate in biogas or composting plants, owing to the potential presence of opportunistic pathogens, including zoonotic viruses. Effective sanitation is also important in viral epizootic outbreaks and as a routine, ensuring high hygiene standards on farms. This study examined the use of ammonia at different concentrations and temperatures to disinfect hatchery waste. Inactivation kinetics of high-pathogenic avian influenza virus H7N1 and low-pathogenic avian influenza virus H5N3, as representatives of notifiable avian viral diseases, were determined in spiked hatchery waste. Bovine parainfluenza virus type 3, feline coronavirus, and feline calicivirus were used as models for other important avian pathogens, such as Newcastle disease virus, infectious bronchitis virus, and avian hepatitis E virus. Bacteriophage MS2 was also monitored as a stable indicator. Coronavirus was the most sensitive virus, with decimal reduction (D) values of 1.2 and 0.63 h after addition of 0.5% (wt/wt) ammonia at 14 and 25°C, respectively. Under similar conditions, high-pathogenic avian influenza H7N1 was the most resistant, withDvalues of 3.0 and 1.4 h. MS2 was more resistant than the viruses to all treatments and proved to be a suitable indicator of viral inactivation. The results indicate that ammonia treatment of hatchery waste is efficient in inactivating enveloped and naked single-stranded RNA viruses. Based on theDvalues and confidence intervals obtained, guidelines for treatment were proposed, and one was successfully validated at full scale at a hatchery, with MS2 added to hatchery waste.
