“…All the cases showed significant increase with time (P<0.01). Most of the experiments on yeast mold counts of meat show the satisfactory level of YMC 10 2 -10 3 cfu/g (Barros et al, 2007 andHuang et al 2014). In this experiment yeast mold count crossed satisfactory level in almost all the cases at 5 hours and were not satisfactory according to YMC level.…”

This study was conducted to assess the microbial load of Black Bengal goat meat during handling and selling in different markets of Mymensingh, Bangladesh. Total 27 samples were collected from three different places of the city, including KR market, Seshmore and Mesua Bazar. These samples were subjected to determine Total Viable Count (TVC), Total Coliform Count (TCC) and Yeast Mold Count (YMC) by using standard protocols. In raw meat, mean value of TVC were highest in Seshmore market (5.24±0.42 log cfu/g) at 0 hour but having no significant differences with other two places. In case of TCC and YMC highest count were in meat of Mesua Bazar. In case of TCC, difference were observed (P<0.05) among the markets. At 5 hours all the bacterial counts were increased having significant differences with the initial count and in most of the cases the bacterial count crossed the acceptable limit. This was may be due to the unhygienic practices of butchers. Consumers were not conscious. Suggestion has been given to improve the knowledge on hygiene among the meat producers to reduce microbial load.

“…Microbiological contamination can occur at different steps in the lamb chain. Several authors have reported microbiological contamination of ruminant meats and surfaces in slaughterhouses, processing plants, and butcher shops (Barros, Nero, Monteiro, & Beloti, 2007;Battisti et al, 2006;Sharma, Gill, Aulakh, Bedi, & Sharma, 2007;Small et al, 2002;Worsfold & Griffith, 2001). In order to control microbiological food safety, an effective Food Safety Management System (FSMS) should be in place at all actors along the meat supply chain (Nørrung & Buncic, 2008).…”

ResumoO objetivo do presente estudo foi comparar diferentes critérios de classificação e interpretação de análises de Escherichia coli genérica, utilizadas na verificação de controles de processos de abate. Utilizaram-se três critérios para a classificação de 1111 análises de superfície de carcaças bovinas: aceitáveis (negativas); marginais (positivas porém inferiores a um limite superior); e inaceitáveis (acima do limite superior). Como limite superior adotaram-se parâmetros estabelecidos pelas legislações americana (100 UFC/cm²) e australiana (20 UFC/cm²), e dois valores obtidos da média mais duas vezes o desvio padrão dos 1111 resultados (5,31 UFC/cm²) e apenas dos 49 resultados positivos (27,43 UFC/cm²). Para a avaliação das análises, foram comparadas duas estratégias de janela móvel, com limites para a ocorrência de resultados marginais e inaceitáveis. Houve diferença significativa apenas quando utilizados o menor e o maior limites superiores. Com o limite de 5,31 UFC/cm² o número de resultados inaceitáveis (16,32%) foi superior ao esperado estatisticamente. Com 100 UFC/cm², observaram-se apenas resultados aceitáveis. Essa variação demonstra que o uso de um limite inadequado poderia levar a tomada de medidas corretivas excessivas ou insuficientes, prejudicando o controle de processos. Contudo, quando os resultados foram aplicados às duas metodologias de janela móvel, não foram observadas diferenças significativas quanto ao número de ações corretivas a serem tomadas. Portanto, a média da contagem de E. coli calculada em cada estabelecimento, obtida somente dos resultados positivos, somada ao uso de uma janela móvel, mostra-se a ferramenta mais aplicável para um diagnóstico contínuo e manutenção do controle de processos de abate.Palavras-chave: análise bacteriológica, carcaça bovina, Escherichia coli genérica. AbstractEscherichia coli tests are used to verify the adequacy of slaughter process controls whit respect to fecal contamination. This research aimed to evaluate different performance criteria for generic E. coli test results, in 1111 swab samples of beef carcasses. Results were classified as acceptable, marginal and unacceptable by the American and Australian standards, 100 and 20 CFU/ cm² respectively, and two parameters calculated according Brazilian guidelines considering the mean plus two standard deviations: 5.31 CFU/cm², obtained from the total of results; and 27.43 CFU/cm² considering only positive samples. Only the limits of 5,31 and 100 CFU/cm² did not present the expected distribution of marginal and unacceptable results (83.68% and 16.32%; and 100% and 0%, respectively), and could lead to excessive or insufficient corrective actions to prevent fecal contamination. The evaluation of E. coli results were performed using two strategies of a moving window approach, considering 13 or 15 consecutive samples and limits on occurrence of marginal and unacceptable results. No significant differences were observed in the number of necessary corrective actions, which indicates that moving window approa...
