“…The last measurement point (location 5) considerably differed from other ones in this respect. Microorganisms, including E. coli, can be transferred over long distances (Cox & Wathes, 1995, Radon, 2007, Ritz et al, 2006, Stetzenbach et al, 2004. It is important that such objects were specially secured and fenced with screens preventing the entry of contaminated air to the surrounding areas.…”

The presence of Escherichia coli in the air of facilities involved in management and composting of post-slaughter poultry wastes in selected plants of West Western Pomerania region was studied. Measurements were made on four dates in a variety of weather conditions during the year. The study was conducted at 5 objects that differ in the type of waste and the degree of preparation for composting. These were: chemical treatment and preliminary processing plant, liquid wastes reservoir, platform for preparation of materials for composting, storage of biological sediments, and composting facility. Measurement of bacteria count was carried out in accordance with the applicable procedures on selective chromogenic TBX medium. The assays revealed the presence of E. coli at all test objects, but not always on all measurement dates. It has been shown that the presence of E. coli was from 20 to 3047 CFU•m -3 of air, although the largest quantities were most frequently detected in the air of the building for post-slaughter waste pre-treatment in chemical treatment plant.

“…Reductions in PM concentrations indoors are in agreement with lower ranges of reductions reported for PM concentrations in other studies. Higher reductions of PM concentrations, 43% in a broiler house (Ritz et al, 2006), and 61% in a broiler breeder house (Mitchell et al, 2004) have been reported. These higher reduction percentages are probably only referred to PM10, as regards to different PM fractions (PM10 and PM2.5), as in our experiment.…”

“…For odor, control levels were above the reference level of 0.24 ou E s -1 bird -1 for Dutch broiler houses (Infomil, 2009). Some studies have presented reductions of NH 3 when using ionization in broiler houses (Mitchell et al, 2004;Ritz et al, 2006). However, results are ambiguous, with reductions ranging from 13 to 56%.…”

“…Concentrations and emissions of PM emissions can therefore be reduced in any of the steps described in Figure 2.6. Research has given ground to the development of a wide range of PM reduction strategies, which have proven to be efficient in livestock systems: "low-dust" feed Nannen et al, 2005), dedusted bedding material, use of feed additives Takai and Pedersen, 2000;Zhang et al, 1995), water or oil sprinkling (Takai and Pedersen, 2000;Zhang et al, 1995), changes in ventilation rate and air distribution (Aarnink and Wagemans, 1997;Gustafsson andvon Wachenfelt, 2006), vacuum cleaning (Nilsson, 1982), end-of-pipe techniques (filtration and wet scrubbing) (Bottcher et al, 2000;Kosch et al, 2005;Melse and Ogink, 2005;Willis et al, 1987;Zhang et al, 2005), and electrostatic precipitation and ionization Dolejs et al, 2006;Mitchell et al, 2000;Mitchell et al, 2004;Ritz et al, 2006;. These strategies can be classified into three main groups: source-control techniques which aim at reducing PM emission from the source, dilution and effective air room distribution, and PM removal or air cleaning techniques (e.g.…”

High ambient concentrations of PM can threaten human and animal health and welfare, as well as the environment. The best approach to reduce PM emissions from livestock houses seems to be to prevent it from being generated. Controlling PM at source not only reduces emissions but also improves inside air quality. Furthermore, data on particle morphology...

Due to greater consumption of poultry products and an increase in exports, more poultry houses will be needed. Therefore, it is important to investigate ways that poultry facilities can coexist in close proximity to residential areas without odors and environmental challenges. Ammonia (NH) is the greatest concern for environmental pollution from poultry production. When birds consume protein, they produce uric acid, ultimately converted to NH under favorable conditions. Factors that increase production include pH, temperature, moisture content, litter type, bird age, manure age, relative humidity, and ventilation rate (VR). NH concentration and emissions in poultry houses depend on VR; seasons also have effects on NH production. Modern ventilation systems can minimize NH in enclosed production spaces quickly but increase its emissions to the environment. NH adversely affects the ecosystem, environment, and health of birds and people. Less than 10 ppm is the ideal limit for exposure, but up to 25 ppm is also not harmful. NH can be minimized by housing type, aerobic and anaerobic conditions, manure handling practices, litter amendment, and diet manipulation without affecting performance and production. Antibiotics can minimize NH, but consumers have concerns about health effects. Administration of probiotics seems to be a useful replacement for antibiotics. More studies have been conducted on broilers, necessitating the need to evaluate the effect of probiotics on NH production in conjunction with laying hen performance and egg quality. This comprehensive review focuses on research from 1950 to 2018.
