We report a case of a 17-year-old female adolescent who experienced an episode of exercise-induced anaphylactic reaction following ingestion of tuna sandwich (from soy containing canned tuna). Her medical history revealed that she had previously had one episode of urticaria after ingestion of sulfamethoxazole with trimethoprim and anaphylactic reaction after ingestion of sunflower nuts. Skin pr...

Seafood is increasingly marketed as the clean, healthy choice for consumers – full of good oils and proteins and low in fat – with canned tuna a favourite cheap source of healthy protein. But science provides everworsening reports on the state of many fisheries, and their effect on marine ecosystems. As international conservation negotiations flounder, consumers and industry are increasingly re...

The identification of biodiversity hotspots and their management for conservation have been hypothesized as effective ways to protect many species. There has been a significant effort to identify and map these areas at a global scale, but the coarse resolution of most datasets masks the small-scale patterns associated with coastal habitats or seamounts. Here we used tuna longline observer data ...

The use of community-based participatory research (CBPR) methods to conduct environmental exposure assessments provides valuable insight about disparities in seafood consumption and contaminant exposure. Ninety-five community-specific seafood consumption surveys were administered to low-income African-American women (ages 16-49) residing in the Southeast community of Newport News, VA, USA, for ...

The results of a study on the microbiological stability of canned tuna produced by Italian companies and similar canned products manufactured in countries outside Europe are reported herein. The study involved 38 samples of canned tuna of various brands, of which 14 were produced by companies outside Europe and 24 by Italian companies. Qualitative and quantitative microbiological tests were con...

A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of the system for X, the biosensor was characterized for X and Hx. A linearity was obtained in the concentration range between 5.00 x 10(-7) and 1.00 x 10(-5) M for X with equation...

Exposure to mercury from environmental sources, such as fish consumption, poses potential health risks to the public. The state of Vermont has developed educational brochures and posters displaying safe fish consumption guidelines in order to educate the public regarding mercury exposure through fish. In this study, a group of medical students from the University of Vermont College of Medicine,...

Immunoassays were developed for the simultaneous detection of staphylococcal enterotoxin B and botulinum toxoid A in buffer, with limits of detection of 0.1 ng/ml and 20 ng/ml, respectively. The toxins were also spiked and measured in a variety of food samples, including canned tomatoes, sweet corn, green beans, mushrooms, and tuna.
