Efficiency of Sanitary Treatment in Poultry Breeding and Poultry Meat Processing Plant

Abstract

The aim of this study was to observe the effectiveness of disinfection on a broiler farm and in a plant processing the poultry from this farm. The broiler farm was disinfected with a preparation based on peracetic acid while a preparation based on quarternary ammonium salt was used in the processing plant. We evaluated swabs taken from surfaces, which come into contact with broilers and broiler meat. Results of the swabs taken by standard microbiological swabbing method were evaluated with results of the swabs taken by the ATP-bioluminescence method. The microbiological examination included total counts of microorganisms, coliform count and moulds. When using the standard plate counts method on the broiler farm we found that the plate counts in 0% of swabs were < 1, in 12% of swabs ranged between 1 -100 CFU while in 88% of swabs reached > 100 CFU. In the processing plant, out of 22% of swabs < 1 CFU were recovered, in 36% of swabs plate counts ranged between 1 -100 CFU and in 42% of swabs plate counts reached > 100. The bioluminescence method was applied only in the processing plant where < 100, 100 -300 and > 300 RLU were measured in 80, 10 and 10% of swabs, resp. Our observations and results allowed us to conclude that the disinfectants tested appeared suitable for the respective premises and the ATP bioluminescence method could be use as a as a suitable complement for detection of cleanliness of individual surfaces. Sanitization, disinfection, poultry, processing plant, standard plate countsThe present requirements on the production of high-quality and safe food are a subject of concern of professionals and wide consumer public in advanced countries with terminal impact on economics of agricultural production, particularly the primary production. According to the valid standards in the Slovak Republic, and in the interest of protection of consumer's health and WHO and FAO recommendations, food producers are bound to make steps which eventually prevent the risk associated with consumption of their products (Hofmann 2000;Burdová et al. 2001). As a result, all production stages must comply with the rules of correct operation practice and the HACCP system must be introduced gradually as an extension of correct operation practice. Sanitation processes are an inevitable part of food production as they influence hygiene and outcome of the entire production system (Bremner and Johnston 1996).Poultry industry is one of the most hygiene-conscious sectors of livestock breeding. The cleaning and disinfection in large plants is ensured by specialized sanitation teams.Monitoring of hygiene under operating conditions is ensured by traditional microbiological swabs and lately also by the ATP-detecting bioluminescence method capable of providing information about contamination of surfaces in less than 10 minutes (Green et al. 1999).

“…Decimal reduction values (D values) expressing the exposure time required for a reduction of surviving cell counts by 90% of the initial value were estimated for the first and the second phase by D1= ln 10/k1 and D2= ln 10/k2, respectively. Survival at the transition from the first to the second inactivation phase was estimated by NTr /N0 = 1 -f. The root mean sum of squared error (RMSE) values calculated by GInaFiT for each fit were in the ranges of the coefficients of variations of the spore counts, indicating that the biphasic model was well suited to represent the experimental data (Geeraerd et al, 2005).…”

“…Mean values of the inactivation kinetic data were fitted to a biphasic inactivation model (Cerf 1977) with the GInaFiT macro (Geeraerd et al, 2005). In this model, the relation between survival and exposure time is given by the equation:…”

A new class of quaternary ammonium compounds as potent and environmental friendly disinfectants

“…In addition, QACs are widely used in textiles ( Li, Z.S. et al, 2020b ; Zhang et al, 2018 ), hospitals ( Ogilvie et al, 2021 ; Schrank et al, 2020 ), aquaculture ( Kaskova et al, 2006 ), paper industry ( He et al, 2015 ; Zhao et al, 2020 ), and other fields and for sewage treatment ( Liu et al, 2020 ; Wu and Li, 2008 ). During the COVID-19 pandemic, the use of QAC disinfectants increased rapidly and exposure to QACs was common, especially in the indoor environment ( Zheng et al, 2020 ).…”
