A focus group study with 37 residents of Manhattan, Kansas, was conducted to examine consumers' risk perceptions of foodborne illnesses from eating beef. The four focus-group sessions were designed to determine (1) relative preferences for alternative combinations of public food safety measures (Hazard Analysis Critical Control Points [HACCP], carcass pasteurization, irradiation) and private pr...

Listeria monocytogenes is the agent of listeriosis, a food-borne disease. It represents a serious problem for the food industry because of its environmental persistence mainly due to its ability to form biofilm on a variety of surfaces. Microrganisms attached on the surfaces are a potential source of contamination for environment and animals and humans. Titanium dioxide nanoparticles (TiO2 NPs)...

Food irradiation is acknowledged as a safe process to improve food quality by reducing microbial contamination. Information on the toxicological potential of 2-alkylcyclobutanones (2-ACBs), radiolytic derivatives of triglycerides found exclusively in irradiated food, is scarce. Wistar rats received daily a solution of highly pure 2-tetradecylcyclobutanone (2-tDCB) or 2-(tetradec-5-enyl)-cyclobu...

Gamma radiation has been used as a post-harvest food preservation process for many years. Chestnuts are a seasonal product consumed fresh or processed, and gamma irradiation emerged recently as a possible alternative technology for their post-harvest processing, to fulfil the requirements of international phytosanitary trade laws. After harvest and storage, several problems may occur, such as t...

the immunogenicity of γ-irradiated tachyzoites of a highly virulent strain of toxoplasma gondii (rh strain) was investigated. immunized mice survived challenge infection and displayed increased interferon gamma (inf-γ ) production. on the other hand, nonimmunized controls died after 10 days and displayed a significantly decreased lymphoproliferative response to concanavalin a (con a). no tachyz...

Background: Flour is one of the most important food sources, therefore it must be kept healthy and clean. As a potential pest control modality, we aimed to examine whether flour irradiation is a feasible tool to eradicate Tribolium confusum adults from infected flour considering probable health effects of infested flour consumption. Materials and Methods: unirradiated and irradiated flour were ...

Diabetes mellitus (DM) is a common and serious metabolic disorder throughout the world. Several herbs have been known to cure and control diabetes without any side effects. Corn silk (CS) is one of these herbs that are rich in phenolic and flavonoid compounds that have antioxidant activity. The purpose of this study is to investigate the hypoglycemic and hypolipidemic effect of gamma-irradiated...

In our previous studies carried out on inbred Sprague-Dawley rats, we reported a striking increase in the incidence of tumors following total-body gamma-irradiation [150 rads (1.5 Gy) five times at weekly intervals]. Subsequently, we observed that two or three irradiations, and to a lesser extent even a single irradiation, were sufficient to induce an impressive increase in the incidence of tum...
