Because corrosion is a diffusion-controlled process, it occurs on exposed surfaces. As a result, methods to reduce the activity of the exposed surface, such as passivation and chromate conversion, can increase a material's corrosion resistance.
Foodborne Illnesses Definition: A foodborne illness is an infection or poisoning caused by a bacterium, virus, parasite, or chemical transmitted by food. A foodborne outbreak is an illness event that typically includes two or more people infected from a common food source.
However, the term food poisoning is misleading, since it groups all food-related illnesses by symptoms, rather than by the pathogen that causes the illness such as a toxin, bacteria or virus. Food-related illness or food-borne disease is caused by a wide variety of pathogens and toxins.nfection from food-borne pathogens may be caused by bacteria, parasites or viruses. Common food-borne pathogens are Escherichia coli (E. coli), Salmonella, Norovirus and Listeria. Food-related illnesses from infectious pathogens typically take much longer to produce symptoms than toxins do.
