“…Cleaning and disinfection procedures such as those performed in the European system are fundamental actions in the prevention of aerial dispersion and contamination by Aspergillus (Rajmani et al, 2011;Cafarchia et al, 2014). Adding to this evidence, the present study demonstrated that performing a simple cleaning and disinfection protocol has little efficiency in reducing the fungal contamination of broiler facilities.…”

“…The type of ventilation, air humidity, and ambient temperature (Sajid et al, 2006) can influence the occurrence of Aspergillus in poultry facilities. Therefore, it is important to control the microclimate of the facilities so as to reduce the development of these fungi (Cafarchia et al, 2014;Kapetanov et al, 2015). Conventional poultry facilities, as in the present study, have less microclimate control, mainly regarding ventilation, which can favor dispersion and contamination by Aspergillus (Baracho et al, 2001).…”

“…Therefore, it is important to control the microclimate of the facilities so as to reduce the development of these fungi (Cafarchia et al, 2014;Kapetanov et al, 2015). Conventional poultry facilities, as in the present study, have less microclimate control, mainly regarding ventilation, which can favor dispersion and contamination by Aspergillus (Baracho et al, 2001). It is thus fundamental to adopt procedures that reduce the fungal load of the environment, such as cleaning the facilities.…”

“…Moreover, Aspergillus spp. dispersion in the rural work environment, especially in poultry facilities, is an occupational health problem (Fairs et al, 2010;Chotirmall et al, 2013;Cafarchia et al, 2014). Procedures for cleaning and disinfecting the facilities, as well as microbiological control of feed, are fundamental for reducing the risk of infections in birds and humans (Grezzi, 2007).…”

“…Despite the wide use of water alone for cleaning purposes, studies do not recommend this practice. This also applies to detergents, which although slightly germicidal, are not suitable as disinfectants or sanitizers (Grezzi, 2007;Cafarchia et al, 2014;Kapetanov et al, 2015). Thus, the present study evaluates the influence of two cleaning and disinfection protocols on the frequency of Aspergillus spp.…”

The present study analyzes influence of two cleaning and disinfection protocols on frequency of Aspergillus spp. in broiler facilities. We conducted an observational study, applying two cleaning and disinfection protocols before housing 960 one-day-old broilers randomly allocated in 32 boxes with 30 birds. We considered two types of housing as independent experiments, which differed as to the bedding. First experiment consisted of new bedding materials, which we reused in second experiment. We applied two different treatments, Common treatment included sweeping organic matter, humidifying residual material with low pressure water, washing with water and neutral detergent, with posterior rinsing. European treatment was according to the standards of the manufacturer of disinfectants. Procedures included dry and humid organic matter removal, humidification, washing with high pressure water, application of detergent, rinsing, and application of two compound disinfectants: glutaraldehyde (250 g/L) + formaldehyde (185 g/L); p-chloro-m-cresol (210 g/L). To evaluate the presence of Aspergillus spp., we collected samples from surfaces and equipment before and after cleaning and disinfection, at 7, 14, 28, and 42 days of experimental period. Mycological assessment included streaking on Petri dishes containing AFPA (Aspergillus Flavus and Parasiticus Agar, Sigma Aldrich®). Common cleaning and disinfection treatment led to a higher presence of fungus in floors and walls (83% vs. 0% p = 0.0030 and 50% vs. 0% p = 0.0450) in first and second experiments, respectively. As this study demonstrates by using the European procedures, performing a detailed cleaning and disinfection protocol reduces the presence of Aspergillus spp. in broiler facilities.
