Abstract

Chemical treatments are commonly adopted for poultry houses sanitation. In fact, ordinary floor disinfection is needed to achieve the depletion of pathogenic population (i.e. some species of bacteria and fungi) and reduce the risk of meat contamination. Recently, the increased attention of consumers and operators health, as well as the quality of food, brought farmers to consider environmental friendly alternative methods. A specific two-year experimental research (2005-2007) was carried out in a Central-Northern part of Italy in order to set up new machines and strategies for floor disinfection of poultry houses by means of an open flame. The trials were run in the machine shop of the University of Pisa (indoor, under controlled conditions) and in two different private farms (a broiler house and an outdoor pheasant farm). The first experiment consisted in a series of bench test trials, carried out in order to evaluate the efficiency and the adjustment of LPG fed open flame burners on pre-inoculated steel plates. During the second experiment, the ordinary chemical disinfection strategy was compared, in a broiler house, to the innovative technique, carried out by means of an adapted 1.5 m wide mounted flaming machine. The last experiment consisted in the evaluation of the efficiency and operative performances of a 2 m wide flaming machine prototype built for open air pheasant farms. The results obtained are very promising as, thermal disinfection strategy seems to be very effective on floor pathogens and cheaper than the ordinary chemical one.
