“…Lues et al (2007) found that the highest counts of microorganisms were recorded in the initial stages of processing, comprising the receiving-killing and defeathering areas, whereas the counts toward the evisceration, air chilling, packaging and dispatch areas decreased. Tsola et al (2008) reported a significant (P < 0.001) decrease in both TVC, coliforms and E. coli after internal and external washing. In a Swedish study (Lindblat et al 2006) TVC from 3.4 to 4.4 log cfu/cm 2 was recorded after chilling which is similar to our results.…”

Microbial contamination of poultry carcasses can be influenced by many factors during transport and slaughtering. The aim of this study was to evaluate the impact of four processing steps (plucking, evisceration, washing and chilling) on the total viable counts (TVC), counts of Escherichia coli, Salmonella spp. and Listeria spp. incidence on broiler carcasses. A total of 160 broiler carcasses originating from one farm were collected during one year period at a Czech slaughterhouse and examined. Both TVC and E. coli counts decreased during processing from 4.6 log cfu/cm 2 and 3.5 log cfu/cm 2 to 3.7 log cfu/cm 2 and 1.8 log cfu/cm 2 , respectively, with a major impact of washing on TVC and washing and chilling on E. coli decrease (P < 0.001). Both Salmonella spp. (6 strains) and Listeria spp. (12 strains, none of L. monocytogenes) were found sporadically in all processing steps followed. However, a decreasing trend was observed in Salmonella counts and Listeria spp. incidence during the processing. Thus, this study brings new valuable information on the dynamics of microflora during modern poultry processing.

“…Despite indicating the hygienic conditions of production, the distinct microorganisms groups present in chicken carcasses can also contribute to the spoilage of these products when present at high counts (ÁLVAREZ-ASTORGA et al, 2002;TSOLA et al, 2008). For avian products some guidelines are suggested, such as the limit of 6log 10 cfu g -1 of MA and 3log 10 cfu g -1 of EC, specifically in Spain.…”

“…The slaughterhouse is considered an ideal environment for spreading antimicrobial-resistant zoonotic pathogens that contaminate surfaces, meat products, and wastewater (56,57). The spread of antimicrobial resistance genes throughout the food chain increases the resistance gene pool from which both pathogens and commensals can pick up resistance determinants, including those that pose a potential threat to public health and ecological balance (21,58,59).…”

The aim of this study was to investigate the phenotypic and genotypic antibiotic resistance profiles of pseudomonads isolated from surfaces of a goat and lamb slaughterhouse, which were representative of areas that are possible sources of meat contamination. Mesophilic (85 isolates) and psychrotrophic (37 isolates) pseudomonads identified at the species level generally were resistant to sulfamethoxazole, erythromycin, amoxicillin, ampicillin, chloramphenicol, trimethoprim, rifampin, and ceftazidime (especially mesophiles), as well as colistin and tetracycline (especially psychrotrophes). However, they generally were sensitive to ciprofloxacin, gentamicin, imipenem, and kanamycin regardless of species identity. Worryingly, in the present study, we found multidrug resistance (MDR) to up to 13 antibiotics, which was related to intrinsic and acquired resistance mechanisms. Furthermore, a link between various antimicrobial resistance genes was shown for beta-lactams and tetracycline, trimethoprim, and sulfonamides. The distribution and resistomebased analysis of MDR pseudomonads in different slaughterhouse zones indicated that the main sources of the identical or related pseudomonad strains were the animals (feet and wool) and the slaughterhouse environment, being disseminated from the beginning, or entrance environment, to the environment of the finished meat products. Those facts must be taken into consideration to avoid cross-contamination with the subsequent flow of mobile resistance determinants throughout all slaughterhouse zones and then to humans and the environment by the application of adequate practices of hygiene and disinfection measures, including those for animal wool and feet and also the entrance environment.
