Outbreak epidemiologically linked with a composite product of beef, mechanically separated chicken and textured vegetable protein contaminated with multiple serotypes of Salmonella enterica including multidrug-resistant Infantis, California 2016

Abstract

A salmonellosis outbreak occurred at a California prison in April and May 2016. In a cohort study of 371 inmates, persons who consumed dishes from the prison kitchen made from ground meat had a higher attack rate (15%) than those who did not (4%) (risk ratio 3.4, 95% CI 1.1-10.6). The ground meat product was composed exclusively of beef, mechanically separated chicken (MSC) and textured vegetable protein; eight of eight lots of the product collected from the prison and processing facility were contaminated with Salmonella enterica of eight serotypes and 17 distinct PFGE patterns, including multidrug-resistant S. Infantis. Either the MSC or the beef could have been the source of the particular strains of S. enterica isolated from patients or the product. The microbiological evidence is most consistent with MSC as the source of the high levels of S. enterica in the epidemiologically linked meat product. Our findings contribute to the growing body of evidence about the hazard posed by the use of products containing raw mechanically separated poultry in kitchens in institutions.

Prevalence of Salmonella species and factors associated with contamination of mechanically recovered poultry meat imported into South Africa, 2016–2017

“…In this study, the proportion of Salmonella positive MRPM consignments was higher than the 15% that was reported in California [45] and 13% reported in Belgium [46]. In contrast, higher prevalences of Salmonella species in MRPM have been reported in the United States (44.6%) [47] and Estonia (38.5%) [48], while Rania and Qasem reported no Salmonella species from MRPM in Jordan [49].…”

“…MAE taşıyabileceği olası patojen bakteriler yönünden incelendiğinde, 2014 yılında ABD'de tüketilen bir et ürününe bağlı meydana gelen Salmonella Heidelberg salgınında MATE'nin kaynak olduğu rapor edilmiştir (9). Yine aynı ülkede 2016 yılındaki bir diğer salgında Salmonella enterica'nın kaynağı olarak MATE gösterilmiş olup etkene ait serovarlar Enteritidis, Heidelberg, Infantis, Kentucky, Schwarzengrund, Senftenberg ve Typhimurium olarak izole edilmiştir (25).…”

El estudio retrospectivo de cohorte durante la investigación de campo de una epidemia

“…Cuadro 4. Distribución del riesgo de diarrea en viviendas de un área de nivel de ingresos bajos sin suministro de agua entubada después del sismo del 19 El cuadro 4 muestra que no hay una tendencia o variación concomitante por si misma entre la disminución del abasto de agua, esto es el RR no aumentó digamos a valores intermedios, digamos entre 2-4 para quienes tenían entre 10 y 20, sino que se mantuvo en el valor nulo de 1, y solamente se elevó en el 17% de la cohorte con menos de 10 cubetas por día. En efecto si se colapsan las categorías de 10+ cubetas por día, se obtendría el mismo resultado (RR=8.4).…”
