Food Safety
Food safety is a major focus of food microbiology. Pathogenic bacteria, viruses and toxins produced by microorganisms are all possible contaminants of food. However, microorganisms and their products can also be used to combat these pathogenic microbes. Probiotic bacteria, including those that produce bacteriocins, can kill and inhibit pathogens. Alternatively, purified bacteriocins such as nisin can be added directly to food products. Finally, bacteriophages, viruses that only infect bacteria, can be used to kill bacterial pathogens. Thorough preparation of food, including proper cooking, eliminates most bacteria and viruses. However, toxins produced by contaminants may not be heat-labile, and some are not eliminated by cooking

Famous quotes containing the words food and/or safety:
“Would mankind be but contented without the continual use of that little but significant pronoun “mine” or “my own,” with what luxurious delight might they revel in the property of others!... But if envy makes me sicken at the sight of everything that is excellent out of my own possession, then will the sweetest food be sharp as vinegar, and every beauty will in my depraved eyes appear as deformity.”
—Sarah Fielding (1710–1768)
“The high sentiments always win in the end, the leaders who offer blood, toil, tears and sweat always get more out of their followers than those who offer safety and a good time. When it comes to the pinch, human beings are heroic.”
—George Orwell (1903–1950)
