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.
Foodborne diseases are the illnesses contracted from eating contaminated food or beverages. Illnesses include foodborne intoxications and infections, which are often incorrectly referred to as food poisoning. There are more than 250 different foodborne diseases. They are caused by viruses, bacteria, parasites, toxins, metals, and prions. Symptoms of foodborne illness range from mild gastroenteritis to life-threatening neurologic, hepatic, and renal syndromes.
