aquatic organisms are one of most important human food sources but they can accumulate heavy metals entered aquatic ecosystems in their tissues and organs same time and can be transferred through the food chain to higher food levels and in the most top into the human body. shrimps are of the main groups of sea foods; and because they are benthic species, they can absorb high concentrations of h...
Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...
biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. the cultivation of genetically modified (gm) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. considering the fast pace of new advances in production of genetically modified crops,...

However, animal feeds can be contaminated with undesirable substances such as dioxins, mycotoxins, heavy metals, pesticides and veterinary drugs at any time during the processing, storage and dispersal. These substance can be transmitted through...
Background Low-moisture foods, such as nuts, generally have been considered low risk for foodborne illness because they are consumed in a dry state. In low-moisture foods the water activity (available moisture) is too low to support microbial growth. For example, the water activity in tree nuts is generally less than 0.7. This may lead to the common misconception that low levels of pathogenic b...
Animal production has moved quite rapidly to a consolidated structure of fewer, larger farms, ranches, and animal feeding units in both developed and developing countries. Driven by economies of scale arising from steady advances in technology, the trend shows no sign of slowing. This new structural concept and features increased concentration of large-scale livestock and specialty crop product...
