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.
A foodborne illness is any illness that results from consuming food contaminated with pathogenic microorganisms, or toxic compounds released by microorganisms. The disease-causing microorganisms are most often bacteria, but can also include fungi, viruses and protozoa.
