The objective of this study was to compare the efficiency of washing and trimming broiler carcasses to reduce bacterial contamination. At the postevisceration site, 100 broiler carcasses were collected during 4 visits to a slaughterhouse in Santa Catarina State, Brazil. Birds were from the same flock, age, and approximately 2.4 kg of weight. Groups were as follows: group 1, with fecal contamination; group 2, without fecal contamination; group 3, with fecal contamination and trimmed; group 4, with fecal contamination and washed; group 5, with fecal contamination, and washed and trimmed. Carcass washings were performed with at least 1.5 L/bird of potable water (0.5 to 1 mg/kg of residual chlorine) at room temperature (20-25°C) using spray cabinets with 44 spray nozzles distributed into 2 chambers (pressure of 2 kgf/cm(2) and 4 kgf/cm(2)). Washed carcasses (trimmed or not) showed significantly (P < 0.05) lower counts of aerobic mesophiles (plate count agar) on the third evaluation, and even lower (P < 0.01) counts for total coliforms (CT) and fecal coliforms (Escherichia coli). Trimmed carcasses showed significantly lower counts (P < 0.05) for plate count agar; however, we observed higher counts for E. coli (P < 0.05). The association of both treatments (washing and trimming) showed significantly higher (P < 0.05) counts for coliforms (CT and E. coli). We can conclude that the washing method is overall more efficient than the trimming method to decontaminate chicken carcasses at the postevisceration site. Hopefully, our findings can help poultry companies to minimize production costs by applying the washing method for carcass decontamination.
O consumo de papinhas para linha infantil cresce com o passar dos anos e tem ganho cada vez mais destaque no mercado brasileiro visto a sua grande praticidade. Em paralelo, tem-se um aumento significativo na ingestão excessiva de sódio e potássio pelos consumidores, também oriundo da alta ingestão de produtos industrializados. Assim, este trabalho objetivou quantificar o teor de sódio e potássio em papinhas infantis, utilizando o método de fotometria de chama, em vinte e sete amostras de papinhas infantis de três diferentes marcas comercializadas na cidade de Chapecó/SC. Para investigação, utilizou-se papinhas industrializadas e papinhas orgânicas. Os resultados foram submetidos à análise de variância (ANOVA) e, em seguida, ao teste de comparação de médias Tukey ao nível de significância de 5% (p<0,05). Para sódio, todas as amostras, independente de sua origem, ultrapassaram os valores descritos no rótulo e sua ingestão diária de 1500 mg/dia. A papinha orgânica 8 a base de carne foi a que apresentou maior valor, 12,262 mg de sódio/g da amostra. Para potássio, todas as amostras ultrapassaram o valor da ingestão diária, 3,5 mg/dia. Com isto ressalta-se a importância de implantar e manter programas de monitoramento de alimentos no país bem como o fornecimento de ferramentas para auxiliar as indústrias no controle de adição de sal na alimentação.
