AIMS Raw fruits and vegetables have been increasingly associated with human infections caused by Shiga toxin-producing Escherichia coli. This study evaluates the isolation and detection of E. coli O26, O111 and O157 from vegetable samples using immunomagnetic particles. METHODS AND RESULTS Standard cultivation and immunomagnetic separation (IMS) procedures were compared. It was found that imm...

The aim of the present study was to verify the association between seropositivity for IgG anti-Toxoplasma gondii antibodies and social, economic and environmental variables of pregnant women attending the public health centers of Paraná, Brazil. From January 2007 to July 2010, 2226 pregnant women were interviewed and detection of anti-T. gondii specific IgG and IgM antibodies was performed by c...

Faba beans are widely consumed in Egypt as a vegetable by many ways. A study was conducted to determine the levels of phenolic compounds and antioxidant properties of raw seeds, green seeds and sprouts of ten faba bean cultivars commonly consumed in Egypt. Nubaria 2, Sakha 2 and Nubaria 1 cultivars showed higher amounts of phenolic compounds and exhibited the highest antioxidant activities (DPP...

BACKGROUND Toxoplasma gondii infections during pregnancy can result in abortion or congenital defects. Prevalence and risk factors of toxoplasmosis in women of child-bearing age in Ethiopia are unknown. The current study was conducted with the objectives of estimating the seroprevalence and potential risk factors in acquiring T. gondii infection by women of child-bearing age in Central Ethiopia...

BACKGROUND Cabbage vegetables, like Brassica group, are perceived as very valuable food products. They have a very good nutritive value, high antioxidant activity and pro-healthy potential. Especially, kale (Brassica oleracea L. var. acephala) is characterized by good nutritional and pro-healthy properties, but this vegetable is not popular in Poland. The aim of this work was to assess the chem...

Vegetable oils and fats may be used as cheap substitutes for milk fat to manufacture imitation cheese or imitation ice cream. In this study, 400 MHz nuclear magnetic resonance (NMR) spectroscopy of the fat fraction of the products was used in the context of food surveillance to validate the labeling of milk-based products. For sample preparation, the fat was extracted using an automated Weibull...

OBJECTIVE Brassica vegetable consumption (e.g. broccoli) leads to excretion of isothiocyanates (ITC) in urine. We evaluated the consistency of ITC as a biomarker for dietary Brassica vegetable consumption across the types of vegetables and methods of preparation used in Western societies, and across consumption levels. DESIGN A single-armed behavioural intervention with duplicate baseline ass...
