House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room te...

In March 1995, the US Food and Drug Administration approved a live attenuated varicella vaccine for use in healthy children 12 months to 12 years old. We report here an 18-month-old girl with cell-mediated immunodeficiency who developed a severe vaccine-associated rash and clinical evidence of vaccine-associated pneumonia 1 month after inadvertent receipt of varicella vaccine.

This article investigates the conceptual and methodological challenges to develop a set of baseline indicators for South African food security targets. A food security target is a well-defined and measurable goal to reduce the numbers of people who lack enough food of the right quality to live healthy lives. To derive baseline indicators for household food security, the following question is as...

301 THE FOOD AND AGRICULTURE ORGANIZATION (FAO) of the United Nations describes live animal transport as “ideally suited for spreading disease,” given that animals may originate from different herds or flocks and are “confined together for long periods in a poorly ventilated stressful environment.”1 Given the associated “serious animal and public health problems,” the Federation of Veterinarian...

In Southeast Asia, swamp eels (Synbranchidae: Monopterus spp.) are a common source of human gnathostomiasis, a foodborne zoonosis caused by advanced third-stage larvae (AL3) of Gnathostoma spp. nematodes. Live Asian swamp eels are imported to US ethnic food markets, and wild populations exist in several states. To determine whether these eels are infected, we examined 47 eels from markets and 6...

BACKGROUND AND OBJECTIVES Infants who live in households experiencing food insecurity are at risk for negative health and developmental outcomes. Despite large numbers of households within our population experiencing food insecurity, identification of household food insecurity during standard clinical care is rare. The objective of this study was to use quality-improvement methods to increase i...

Parasitism is the most common consumer strategy among organisms, yet only recently has there been a call for the inclusion of infectious disease agents in food webs. The value of this effort hinges on whether parasites affect food-web properties. Increasing evidence suggests that parasites have the potential to uniquely alter food-web topology in terms of chain length, connectance and robustnes...

We have developed a paper-based analytical device as a platform for colorimetric detection of pathogenic bacteria responsible for foodborne illness. The food industry currently relies on time-consuming and complex analysis techniques to determine the presence of live Escherichia coli, Listeria monocytogenes, and Salmonella enterica in food products. Advantages of the paper-based design include ...

METHODS We use a geographic information system to measure availability and accessibility of supermarkets in four case study local government areas (LGAs). The location of supermarkets is analysed in relation to residential dwellings, car ownership and in terms of travel distance along the road network. RESULTS This methodology identifies differences in both availability and accessibility betw...
