“…Moreover, our results showed that chicken had the highest level of contamination, while packaged products such as sausages and hot dogs had the lowest level of contamination. These findings are consistent with other reports in which the highest amount of microbial contamination was found in chicken and the lowest in sausage, respectively ( Cansian et al, 2005 ; Ibrahim et al, 2014 ; Trimoulinard et al, 2017 ). These results suggest that chicken may be a potential source of Actinomycetes contamination in meat and meat products and highlight the importance of implementing appropriate measures to ensure the safety of meat and meat products for consumers.…”

“…In this study, according to the mentioned statistical formula, the number of sampling locations, and the number of samples in similar studies, 60 meat and meat products samples were collected, of which 21 (35%) actinomycete isolates were isolated. This isolation rate is consistent with other actinomycete isolation reports ( Cansian et al, 2005 ; Ibrahim et al, 2014 ; Trimoulinard et al, 2017 ). However, this result cannot be accurately reported as the prevalence rate due to the limitation and small volume of samples.…”

IntroductionActinomycetes can colonize surfaces of tools and equipment and can be transferred to meat and meat products during manufacture, processing, handling, and storage. Moreover, washing the meat does not eliminate the microorganisms; it only spreads them. As a result, these opportunistic pathogens can enter the human body and cause various infections. Therefore, the aim of the current study was to screen, identify, and determine the antibiotic susceptibility of Actinomycetes species from meat and meat products in the Markazi province of Iran.MethodsA total of 60 meat and meat product samples, including minced meat, mutton, beef, chicken, hamburgers, and sausages, were collected from slaughterhouses, butchers, and restaurants in the Markazi province of Iran. The samples were analyzed using standard microbiological protocols for the isolation and characterization of Actinomycetes. PCR amplification of hsp65 and 16SrRNA genes and sequence analysis of 16SrRNA were used for genus and species identification. The minimum inhibitory concentrations (MICs) of antimicrobial agents were determined by the broth microdilution method and interpreted according to the CLSI guidelines.ResultsA total of 21 (35%) Actinomycetes isolates from 5 genera and 12 species were isolated from 60 samples. The most prevalent Actinomycetes were from the genus Mycobacterium, with six (28.6%) isolates (M. avium complex, M. terrae, M. smegmatis, and M. novocastrense), followed by the genus Rhodococcus with five (23.8%) isolates (R. equi and R. erythropolis), the genus Actinomyces with four (19.1%) isolates (A. ruminicola and A. viscosus), the genus Nocardia with four (19.1%) isolates (N. asiatica, N. seriolae, and N. niigatensis), and the genus Streptomyces with two (9.5%) isolates (S. albus). Chicken and sausage samples had the highest and lowest levels of contamination, with six and one isolates. Respectively, the results of drug susceptibility testing (DST) showed that all isolates were susceptible to Ofloxacin, Amikacin, Ciprofloxacin, and Levofloxacin, whereas all of them were resistant to Doxycycline and Rifampicin.DiscussionThe findings suggest that meat and meat products play an important role as a reservoir for the transmission of Actinomycetes to humans, thus causing life-threatening foodborne diseases such as gastrointestinal and cutaneous disorders. Therefore, it is essential to incorporate basic hygiene measures into the cycle of meat production to ensure food safety.

“…Despite the fact that 19 named species have been classified, only few of them are recognized as human pathogens, such as A. hydrophila complex, A. caviae and A. veronii, representing almost 85% of the clinical isolates, although other species have been recovered from the clinical sources (Janda and Abbot, 1998). Aeromonads are also found in a variety of sources, such as the food (Granum et al, 1998;Cansian et al, 2005;Ullmann et al, 2005;Martin Talavea et al, 2006), natural water (Ghenghesh et al, 2001;Østensvik, 2001, Sousa andSilva-Souza 2001) and drinking water (Kuhn et al, 1997;Villari et al, 2003), and it is known that psycrophilic species are mainly etiologic agents in the fishes (Garduño et al, 2000). In human immunocompetent hosts, the members of this genus may be responsible for the intense gastroenteritis, called traveler's diarrhea (Janda and Abbot, 1998;Vila et al, 2003), but in the immunocompromised hosts, these bacteria could be implicated in the cases of myonecrosis, bacteremia, septicaemia (Martino et al, 1997) and hepatic cirrhosis and neoplasys (Chien Ko and Chuang, 1995).…”

“…Processing a chicken for the human consumption requires 12 to 24L of water (Chaves et al, 2005). According to the Brazilian Union of Aviculture, the production of chicken in 1998 was around 4.5x10 6 ton (Cansian et al, 2005). The variation in quantity and organic load present in the effluents from different industries depends on the degree of recycling and care taken during the operation, particularly with blood (Ruiz et al, 1997;Pohlmann, 2004).…”

The effectiveness of the anaerobic treatment of effluent from a swine and bovine slaughterhouse was assessed in two sets of two-phase anaerobic digesters, operated with or without temperature control. Set A, consisting of an acidogenic reactor with recirculation and an upflow biological filter as the methanogenic phase, was operated at room temperature, while set B, consisting of an acidogenic reactor without recirculation and an upflow biological filter as the methanogenic phase, was maintained at 32°C. The methanogenic reactors showed COD (Chemical Demand of Oxygen) removal above 60% for HRT (Hydraulic Retention Time) values of 20, 15, 10, 8, 6, 4, and 2 days. When the HRT value in those reactors was changed to 1 day, the COD percentage removal decreased to 50%. The temperature variations did not have harmful effects on the performance of reactors in set A.
Avaliou-se a eficiência do tratamento anaeróbio de efluente de matadouro de suínos e bovinos em dois conjuntos de biodigestores anaeróbios de duas fases, operados com e sem controle de temperatura. O conjunto A, formado por um reator acidogênico com recirculação e um filtro biológico de fluxo ascendente, foi operado a temperatura ambiente e o conjunto B, formado por um reator de fluxo ascendente e um filtro biológico de fluxo ascendente, foi mantido a 32°C. Os reatores metanogênicos apresentaram remoção de DQO acima de 60 % para os TRHs de 20, 15, 10, oito, seis, quatro e dois dias. Quando o TRH destes reatores foi mudado para um dia observou-se uma queda da porcentagem de remoção de DQO para 50 %. As variações de temperatura parecem não ter prejudicado o desempenho dos reatores do conjunto A
