The aim of the study was to evaluate the microbiological and chemical contamination in settled dust at poultry farms. The scope of research included evaluating the contributions of the various granulometric fractions in settled dust samples, assessing microbial contamination using culture methods, concentrations of secondary metabolites in dust and their cytotoxicity against hepatocyte chicken ...

Cimex lectularius L. is a widespread hematophagus insect pest around the world and is currently experiencing a reemergence as a public health pest of concern. One possible source of bed bugs to the human environment is the movement of bed bugs from poultry facilities to human structures by poultry workers. No recent studies have been conducted on the susceptibility of this insect to a wide rang...

Recognising how difficult it is for some countries to fully eliminate animal diseases from their territory as a whole or to maintain an animal disease free status in parts of their national territory, the World Organisation for Animal Health (OIE) has introduced the concepts of 'zoning' and 'compartmentalisation' for the purposes of disease control and international trade. Full definitions of t...

In 1989 and 1990, a case-control study designed to identify risk factors for sporadic infections with thermotolerant Campylobacter bacteria was conducted in three counties in southeastern Norway. The investigation was confined to infections which were acquired in Norway. A total of 52 bacteriologically confirmed cases and 103 controls matched by age, sex, and geographic region were interviewed....

A wide variety of zoonotic disease risks exists in poultry. Popularity of backyard and smaller production flocks is increasing, as is public concern about global poultry disease events. This paper discusses several of the more common poultry zoonotic diseases, their prevalence and presentation in both poultry and humans.

New waste management methods are needed that can protect the environment and allow manure management to switch back to a recycling view of manure handling. We investigated the use of gas-permeable membranes as components of new processes to capture and recover the ammonia in the liquid manures or in the air of poultry houses and other livestock installations. The basic process includes the pass...

Nature of the Industry Workers in the food manufacturing industry link farmers and other agricultural producers with consumers. They do this by processing raw fruits, vegetables, grains, meats, and dairy products into finished goods ready for the grocer or wholesaler to sell to households, restaurants, or institutional food services. Food manufacturing workers perform tasks as varied as the man...

The aerial spray prediction model AgDRIFT embodies the computational engine found in the near-wake Lagrangian model AGricultural DISPersal (AGDISP) but with several important features added that improve the speed and accuracy of its predictions. This article summarizes those changes, describes the overall analytical approach to the model, and details model implementation, application, limits, a...
