Migration of nanoparticles from nano-silver food containers

Based on the antimicrobial action of nano-silver, a number of “active” FCMs have been developed that are claimed to extend the shelf-life of food by inhibiting the growth of microorganisms. As commercialization of nano-silver grows, the public and the governments become more concerned about the safety and environmental effects of the widespread use of products containing nano-silver [2]. Several studies have been carried out and they demonstrated the toxicity of nano-silver, which is proved to be hazardous to different kind of cells and edible plants [3-5].
