Peru is currently one of the world’s leading culinary destinations, whose world-renowned cuisine uses vegetables, mainly lettuce, as frequent ingredients. Vegetable consumption promoted worldwide a part healthy diet. However, more frequently have been implicated vehicle infection for several foodborne parasites. This study aimed to determine presence potentially pathogenic parasites in lettuce marketed Central Andes Peru. A total 75 samples were collected from two largest wholesale markets...
Reformulation of cooked sausages using high-protein plant-based food such as chickpea meat extenders and vegetable oils to replace animal fat can be a suitable approach promote the consumption smaller portions meat. The pre-processing sausage cooking intensity potentially affect quality reformulated sausages. In this study, an emulsion-type made with lamb meat, olive oil was prepared in triplicate following three different formulations containing same targeted levels protein (8.9%), lipids...
Abstract Different approaches have been previously studied in order to reduce the fat content of dry‐cured sausages. Among them, use polysaccharides, such as fiber, gums, or starch, proposed for replacing. Although scarcely studied, it is likely that starchy grains and vegetables might also be used potential replacers those Quinua a seed with high nutritive value, which contains substances technological interest manufacturing. The aim this study was assess effect replacing by quinoa on...
Taenia solium taeniasis/cysticercosis is one of few potentially eradicable infectious diseases and the target control programs in several countries. The larval stage this zoonotic cestode invades human brain responsible for most cases adult-onset epilepsy world. pig natural intermediate host, harboring larvae or cysticerci. Our current understanding life cycle implicates humans as only definitive host tapeworm carrier (developing taeniasis) thus sole source infective eggs that are...
The contamination of the surface water lagoons is a common problem in developing countries, and can affect fishing activities. A case study was conducted on quality microbiological marketing chain Peruvian Amazon (Laguna de Yarinacocha). microbiological, physical–chemical parasitological parameters were evaluated three points lagoon near landing stage; facilities, handlers species fish (Prochilodus nigricans, Mylossoma duriventre Siluriforme spp.). In water, there coliform counts ≥ 23 (Most...
Procedures were evaluated for the rapid and efficient purification of oocysts esporocysts Sarcocystis aucheniae (Sa) from small intestine experimentally infected dogs with 400 Sa macrocysts obtained meat naturally alpacas. The mucosa was removed. Samples washed by centrifugation PBS, homogenized centrifuged. Large quantities attached to intestinal microvilli obtained. In first procedure, an ezimatic treatment 5% tripsin used resulting in 50% oocyst separation. second procedure samples...
El objetivo del estudio fue determinar la presencia de Listeria monocytogenes en muestras canales porcinas Lima, Perú. Se muestrearon 88 superficies procedentes un centro beneficio. Las se sometieron a pre-enriquecimiento medio BLEB y enriquecimiento microbiológico caldo PALCAM, el patógeno identificó con técnica molecular detección rápida hibridación in situ. 13.9 ± 6.1% las resultaron positivas L. monocytogenes, posiblemente debido deficiencias aplicación control buenas prácticas...
Reformulation approaches in the meat industry are required to promote nutritional improvement, health functionality, and reduce environmental impact. A relevant approach among these is amount of products. Reduced-meat products should maintain or improve sensory characteristics nutritive value compared conventional Among products, heat-treated emulsion-meat sausages widely consumed especially suitable for reformulation approaches. Due its high protein content, with functionally biological...
The aim of this study was to determine the presence Campylobacter spp in meat and cecum broilers sold three illegal abattoirs Lima, Peru. For purpose, 90 were selected, collecting 60 samples body carcasses by rinse method 30 cecum. cultured mCCDA agar at 42 °C for 48 h under microaerophilic atmosphere, biochemical tests used identify thermotolerant species. results showed that 16.7% positive, where 60% C. jejuni 40% coli. In samples, 26.7% positive spp, 72.7% 27.2%
Physical and chemical methods of home use techniques for sanitation detoxification alpaca meat infected with macrocysts Sarcocystis aucheniae were evaluated. The physical treatments boiling baking at 80 °C 5 minutes freezing 10, 15 20 days; the salting 30 days, marinated 24 hours. Dogs fed bouts treated containing 180-200 presence oocysts analyzed in faeces 18 days. Besides, lisates injected to rabbits evaluate detoxifying effect on protein content macrocysts. Only proved be effective...
El objetivo del presente trabajo fue determinar el perfil de resistencia antibiótica cepas Salmonella enterica aisladas durante proceso beneficio cerdos en un matadero Lima Metropolitana. Se utilizaron 148 muestras heces y ganglios mesentéricos cerdos. La evaluación la se realizó por método difusión disco (Kirby-Bauer). consideraron 13 antibióticos uso frecuente medicina humana, los cuales mayoría ellos son usados también como profilácticos promotores crecimiento. encontró que todas las...
