Straighterline Microbiology Lab BIO250L Lab 6 Food Microbiology Worksheet 2024/2025 (Verified) Escherichia coli is one of the most common causes of foodborne illness, yet it is also a common microorganism found within the human gut. What explains this disparity? E. coli is a bacteria that primarily lives in the intestines and normally has no negative effects on the health of the intestines. However, some strains of pathogenic E. coli, particularly those that generate Shiga toxin, are more likely to contaminate food and water supplies and, if consumed, can cause foodborne diseases. This information was given by the American Food and Drug Administration. 2. There are several foods and beverages listed in this lab that are created through the actions of microorganisms. Name five of the foods and the specific microorganisms that are used to make each of them. Saccharomyces cerevisiae and Lactobacillus can be detected in sourdough bread, whereas Swiss cheese contains Propionibacterium freundenreichii. Beer contains Saccharomyces pastorianus, Saccharomyces cerevisiae and, and kimchi containsLactobacillus plantarum and Leuconostoc mesenteroides. The microbes that produce vinegar are Acetobacter and Gluconobacter. Straighterline Microbiology Lab BIO250L Lab 6 Food Microbiology Worksheet 2024/2025 BIO250L 3. Using an online research tool such as the A-Z index on the CDC website, explain why Listeria monocytogenes is a major threat to pregnant women and their developing fetuses, who are ten times more likely to get sick than other demographic groups. Listeria is a bacteria that is frequently discovered in vegetables, particularly unpasteurized dairy products. The Centers for Disease Control and Prevention (CDC) BIO250L reports that soft cheeses, celery, sprouts, melons, and ice cream are frequently implicated in outbreaks. Expectant mothers, their developing fetuses, and women who are already pregnant are all at serious danger from it. Immunity is compromised in people. Pregnant women should be extremely cautious since listeria infection can cause miscarriages, stillbirths, and preterm labor. Infants could result from it. (serious illness and death)
