“…These results highlight the need to improve the quality of raw materials provided by pork slaughterhouses in a screened complex, with particular emphasis on the most important parameters and procedures in each stages, such as timetemperature couples, handling, or general hygiene [9,14]. Considering that Salmonella on the skin of pigs entering the slaughter line is a common finding [3,15], the low Salmonella isolation rate recorded at the scalding point of the investigated slaughterhouse suggests the efficiency of scalding in Salmonella reduction, as was previously demonstrated by Davies et al (1999). On the other hand, contrary to what would be expected, a relatively high frequency isolation rate of Salmonella was observed in the detritus from the hair removal equipment.…”

Introduction: Reported human salmonellosis cases have increased in Romania. Antibiotic susceptibility testing of Salmonella strains isolated from pork and chicken meat indicate a worrying multidrug resistance pattern. This study aimed to investigate the occurrence of Salmonella and to evaluate the antibiotic resistance of Salmonella strains in a pig slaughterhouse-processing complex, which receives animals from 30% of the large industrialized swine farms in Romania. Methodology: A total of 108 samples, including pork (n = 47), packaged pork products (n = 44), scald water sludge (n = 8), and detritus from the hair removal machine of the slaughterhouse (n = 9) were examined for the presence of Salmonella through standard methods. The antibiotic susceptibility of the isolated strains to 17 antibiotics was tested using the Vitek 2 system. Results: Twenty-six (24.1%) samples were found to be Salmonella positive; this included 25.5% of meat samples and 15.9% of packaged products, as well as samples from two different points of the slaughter (41.2%). Resistance was observed against tetracycline (61.5%), ampicillin (50%), piperacillin (50%), trimethoprim-sulfamethoxazole (34.6%), amoxicillin/clavulanic acid (26.9%), nitrofurantion (23.1%), cefazolin (15.4%), piperacillin/tazobactam (7.7%), imipenem (3.8%), ciprofloxacin (3.8%), and norfloxacin (3.8%). No resistance towards cefoxitin, cefotaxime, ceftazidime, cefepime, amikacin, and gentamicin was found. Conclusions: Our study demonstrated the occurrence of multidrug-resistant Salmonella strains in the investigated pork production complex and highlighted it as a potential source of human infections. The results demonstrate the seriousness of antibiotic resistance of Salmonella in Romania, while providing a useful insight for the treatment of human salmonellosis by specialists.

“…However, the numbers of these three groups of microorganisms were not significantly different between skinned and chilled carcasses at the same plant or on the same type of carcasses at the two plants (p >0.05). Total aerobic counts between 10 4 and 10 10 cfu/cm 2 on hides have been reported in studies from various countries (Antic et al, 2010;Bacon et al, 2000;Blagojevic, Antic, Ducic, & Buncic, 2011;Yang, Badoni, Tran, & Gill, 2015;Zweifel, Capek, & Stephan, 2014). Some of those bacteria will inevitably be transferred to the meat during hide removal, from direct contact of hides with carcasses, aerosols generated during pulling of the hides and/or equipment that is used for opening cuts (C.

The objective of this study was to investigate spoilage microflora of decontaminated and not decontaminated beef carcasses. Carcasses after skinning and after chilling at two beef plants (A, a small plant where no interventions but dry chilling are used; B, a large plant where multiple antimicrobial interventions and spray chilling are used) were swab-sampled for determination of carcass microflora. The numbers of aerobes, Pseudomonas, Brochothrix thermosphacta, lactic acid bacteria (LAB), and Enterobacteriaceae (EB) on carcasses at plant A after skinning were 5.2, 3.7, 2.8, 3.9, and 1.6 log cfu 15,000 cm -2 and they were not significantly different (p>0.05) from those on carcasses at plant B at equivalent times. The numbers of EB were significantly lower (p<0.05) on carcasses after chilling at both plants. However, no difference was observed for the other four groups of microorganisms (p>0.05). At plant A, the microflora on carcasses after skinning and after chilling included 18 and 19 bacterial species, with Psychrobacter (30.9%) and Psychrobacter (42.9%) being the respective predominant genus, respectively. At plant B, the microflora after skinning and after chilling included 21 and 17 bacterial species, with Chryseobacterium (18.6%), Kocuria (18.6%) and Brevibacterium (18.6%), and Pseudomonas (33.3%) being the respective predominant genera. The spoilage microflora of decontaminated beef carcasses is similar in numbers to that of conventionally produced carcasses, suggesting the decontamination treatments for beef carcasses may not cause major difference in storage life of chilled vacuum packaged beef, the major form of beef for international and domestic trading in North America.

ResumoO objetivo da presente pesquisa foi avaliar as condições higiênico-sanitárias através do nível de contaminação bacteriológica inicial e a cada duas horas consecutivas de equipamentos da sala de desossa durante a jornada de trabalho, a fim de certificar a eficácia da aplicação de limpeza a seco como procedimento padronizado de higienização operacional. Neste sentido foram coletadas amostras em triplicata para análise bacteriológica no início e a cada duas horas consecutivas da rotina diária de desossa em quatro equipamentos distintos que entram em contato direto com o produto final. Estas coletas foram realizadas durante cinco dias produtivos consecutivos totalizando cinco repetições. As coletas foram realizadas através da técnica do "swab test" e método rápido de análise. As contagens de bactérias aeróbias mesófilas se mantiveram dentro do limite aceitável estabelecido de até 1,0 log UFC.cm -2 para o horário 1 e de até 5,0 log UFC.cm -2 para os demais horários. Todas as contagens de enterobactérias se mantiveram dentro do limite aceitável estabelecido de até 3 log UFC.cm -2 , notando-se que não houve diferenças (p>0,05) entre os valores encontrados nos quatro equipamentos nos diferentes horários amostrados. Sendo assim, a aplicação da limpeza a seco durante toda a jornada de trabalho na sala de desossa é eficaz para o controle da contagem de bactérias aeróbias mesófilas e de enterobactérias, portanto contribui para a produção de alimento seguro ao consumidor.Palavras-chave: carne bovina, contaminação, limpeza, micro-organismos, sala de desossa. AbstractThe objective of the present research were evaluate the sanitary conditions through initial bacteriological contamination level and every two consecutive hours of the deboning room equipments during workday to ensure the effectiveness of dry cleaning application as standardized procedure of operational hygiene. The samples were collected in triplicate for bacteriological analysis was proceded at baseline and every two consecutive hours of deboning daily routine in four different equipments that comes into direct contact with the end product. These samples were taken for five consecutive productive days totaling five repetitions. The collections were made using the technique of swab test and rapid method of analysis. The aerobic mesophilic counts not exceeded the acceptable limit of 1.0 log UFC.cm -2 for one hours and up to 5.0 log UFC.cm -2 for other times. All enterobacteria counts not exceeded the acceptable limit of up to 3.0 log UFC.cm -2 . There were no differences among values observed from the different equipment analyzed. In addition, the application of dry cleaning throughout the workday in the deboning room was an effective control of mesophilic aerobic bacteria and enterobacteria, thus ensuring the production of safe food the consumer.
