“…The accumulation of airborne pollutants, including dust, ammonia, and microbial contaminants, irritates the respiratory tract and compromises lung function. Respiratory distress, a consequence of poor ventilation, predisposes birds to respiratory infections, exacerbating the burden of immunosuppression within poultry populations [111]. Moreover, the high stocking densities characteristic of intensive farming environments foster rapid pathogen transmission.…”

Immunosuppression refers to a condition in which the body’s immune system becomes weakened or suppressed, making them more susceptible to infections, diseases and other health problems. Immunosuppression in poultry can be caused by a variety of factors, including infectious activity (viruses, bacteria, parasites, and fungi), environmental stress, malnutrition, and poor management. Viruses have the most dominant immunosuppressive effect on the poultry population, especially infectious bursitis virus, infectious anemia virus and Marek’s disease virus. Immunosuppression in poultry can have significant consequences on their health, welfare, and overall productivity. The biggest losses in poultry production are reflected in reduced growth and performance of individuals, reduced egg production and shell quality, increased morbidity and mortality rates, and greater susceptibility of immunocompromised individuals to secondary infections. Effective management strategies are key to minimizing the impact of immunosuppression in poultry. Biosecurity measures, strict hygiene protocols, immunoprophylaxis, control, and reduced transport of poultry and people, adequate diet, and correct husbandry and housing conditions are some of the factors that result in prevention and/or solvation of this problem.

“…Workers in broiler houses are consistently exposed to PM due to frequent barn management compared to other livestock species [4,5]. The livestock PM contains various bacteria, molds, and harmful gases, such as ammonia, hydrogen sulfide, methane, acetaldehyde, formaldehyde, methylamine, and carbon monoxide [6][7][8][9]. The aging of agricultural workers raises serious concerns about the health issues resulting from the inhalation of PM, which can lead to respiratory and immune system disorders, as well as conditions such as asthma [10][11][12][13][14][15][16].…”

In livestock houses, particulate matter (PM) is a critical factor not only for disease and odor spread but also for the work environment. In particular, workers are exposed to high concentrations of organic particulate matter and harmful gases while performing their tasks, and, as they age, they become more vulnerable to respiratory diseases. This study analyzed the PM concentrations in commercial broiler houses, focusing on the differences in ventilation rates according to the season and the type of work, categorized into a static work period (SWP) and dynamic work period (DWP). In the regional monitoring using gravimetric methods, the average PM concentrations were found to be within acceptable limits, with TSP at 1042 µg/m3, PM-10 at 718 µg/m3, and PM-2.5 at 137 µg/m3. These values did not exceed the recommended exposure limits for inhalable dust at 2400 µg/m3 and respirable dust at 160 µg/m3 in chicken farmers. However, in the personal monitoring using a real-time aerosol spectrometer, it was revealed that the aerosol concentrations during DWP exceeded the standards by up to 214%. Specifically, during DWP, the concentrations were 1.74 times higher for TSP, 1.40 times higher for PM-10, and 1.22 times higher for PM-2.5 compared to SWP. It was observed that during the movement of workers, the physical generation of particles around 10 µm, such as feed and bedding, occurred due to the movement of chickens, which influenced the aerosol concentration.

“…So, the concentrations of airborne dust and bacteria were higher in broiler houses as compared with laying hen houses [14,18,25], as well as in broiler houses with deep litter systems as compared with other floor systems [26,27]. Other factors that can contribute to poultry house air contamination with dust and bacteria include poultry age, weight and activity, stocking density, lighting programs, type of bedding and feeding, type of ventilation and ventilation rate, farm management, microclimate conditions, and seasons, as well as the method and time of sampling [6,11,20,28,29].…”

This study aimed to investigate dust and bacterial air contamination in a broiler house during different seasons. The study was carried out in commercial housing conditions during five weeks of the rearing cycle in summer and winter. The total dust concentration ranged from 1.90 to 4.50 mg/m3 in summer and from 2.80 to 5.10 mg/m3 in winter. The total bacterial count ranged from 2.85 × 104 to 1.03 × 105 CFU/m3 in summer and from 2.12 × 104 to 2.28 × 105 CFU/m3 in winter. The study results showed the dust concentration to be increased in winter as compared to summer, yielding a significant correlation (r = 0.602, p < 0.05) with a significantly higher airborne bacterial count in winter (p < 0.001). Furthermore, dust concentration showed significant correlations (p < 0.05) with air temperature (r = −0.418), relative humidity (r = 0.673), and broiler activity (r = 0.709), while bacterial count yielded significant correlations (p < 0.05) with air temperature (r = −0.756), relative humidity (r = 0.831), and airflow rate (r = 0.511). The results obtained in the study can prove useful in the field. Seasonal variability in dust and bacterial air contamination should be considered in the development of guidelines or standards of air quality in broiler housing and evaluation of the effectiveness of remedial strategies.
