Sustainable practices meet the needs of the present without compromising the ability of future generations to meet their needs. Applying these concepts to food and feed production, nutritional sustainability is the ability of a food system to provide sufficient energy and essential nutrients required to maintain good health in a population without compromising the ability of future generations ...

Microbiological analyses of chicken eggs in Recife and Salvador have shown a high occurrence of Salmonella in the egg shells and yolks. Likewise, the occurrence of Salmonella plus coagulase-positive staphylococci in Coalho cheese reached alarming levels. The data revealed a significant risk of infections and intoxications from consuming these foods in the cities.

Three consecutive outbreaks of Salmonella enteritidis PT4 occurred in Wales in 1989 in which epidemiological and microbiological investigation established eggs as the likely source although kitchen inspection and food preparation histories suggested other vehicles of infection. This paper examines the contribution of analytical epidemiology in attributing causation, with particular reference to...

A quantitative model was constructed to estimate the probability that a serving of food containing eggs produced on the island of Ireland is contaminated with Salmonella spp. The model is based on the prevalence of contaminated eggs at the time of lay and a set of parameters which describe the pooling of eggs in the home and in catering situations. Both external and internal contamination of th...

The effect of temperature variability on laying birds was studied experimentally, using Japanese quail. Two aspects of temperature variability were investigated: the effects of regular daily variation in temperature, and of a sudden change in temperature. Both of these may become more common as a consequence of climate change. These manipulations were carried out at two levels of food supply. E...

Antinematodal efficacy of Saussurea lappa roots (Qust-e-Shereen) and anticestodal effect of Nigella sativa seeds (Kalonji) was studied in children infected naturally with the respective worms. The activities were judged on the basis of percentage reductions in the faecal eggs per gram (EPG) counts. The 50 mg/kg single dose of S. lappa and equivalent amount of its methanolic extract produced on ...

Four non-host plant extracts from Bifora radians, Arctium lappa, Humulus lupulus and Xanthium strumarium, were tested against adult grape berry moths, Paralobesia viteana, for their potential as repellents or oviposition deterrents. Responses were compared with those elicited by the major component of the P. viteana sex pheromone. Moths of both sexes exhibited varying electroantennogram (EAG) r...

The prevalence of allergy is markedly low in children growing up on farms. An increasing number of studies indicate that the timing of food introduction may affect allergy development. We aimed to investigate if protection against allergy in farm environments may be mediated through differences in food-introduction practices between farm and non-farm families, using an explorative approach. Twe...

Salmonella enteritidis may have been transmitted through the hands of the vendors or from those of vendors who sold egg products in the vicinity. Although raw eggs and egg products have been implicated in contamination with Salmonella enteritidis the ability of this pathogen to survive for up to 7-14 days on the surface of many fresh fruits as in melons have been reported. Since, people of almo...

The aim of this report is to describe breastfeeding duration and introduction of foods in Swedish infants born 1997-9, in relation to current recommendations. A secondary aim is to examine breastfeeding duration and introduction of certain allergenic foods in allergy-risk families (for whom allergy-preventive advice has been issued). Out of 21,700 invited infants, screening questionnaires were ...
