Washed Eggs

The result of this experient shows that lunch meat grows more bacteria than Skittle and bacteria does grow more if we drop it. In the result of lunch meat, tile floor grows the most bacteria and for the Skittle, bacteria grows more on the cotton cloth. During the experient, I find out that it’s interesting that after 12 hours, that control sample for lunch meat grows more bacteria than the lunch meat on cotton cloth.

Schwan’s Sales Enterprise had the largest foodborne illness outbreak in history in Marshall, Minnesota around 1994 (Rubenstein, 1998). Cliff Viessman, a tanker truck operator transported a shipment of raw eggs that may have been infected with salmonella bacteria. The suspected contamination was unknown to Viessman’s employees. A foodborne illness is an infection or irritation of the gastrointestinal that caused by food or beverages that contain harmful bacteria, parasites, viruses, or chemicals. The company truck was parked and pressure washed to eliminate the bacteria. The next assignment was to transport ice cream mix to the Schwan’s plant (Rubenstein, 1998). Schwan’s company heard about the bacteria that may have affected their product and

coli were labeled as bacteria that should not be examined or touch without permission from the supervising teacher. Although the strain of E. coli used in this experiment was harmless, to avoid transmitting the bacteria to other organism, the experimenter handled the E. coli for caution (see Appendix H, I, J, K).

At prison (B), person-to-person transmission and contamination of multiple foods likely contributed to illness. Analysis of stool specimens from inmates identified eight serotypes and 15 pulsed-field gel electrophoresis (PFGE) patterns of Salmonella. This case and the reception case, although on a smaller scale, are very similar. Two distinct PFGE patterns were found in the reception strain of Salmonella, versus the 15 PFGE patterns found at the prisons. In the prison where chicken salad was contaminated, it was found that the eggs and raw chicken used were the causing ingredients. It wouldn’t be too much of an assumption to say that the eggs in the potato salad at the reception could have been contaminated by the

Clostridium is one of the most common food poisoning in the USA. Also it used the less time for regeneration or multiplication of endospores.

Naked Egg Lab Frances Jose Redmond High School Biology, Period 3 Mrs. Sinclair 7 November 2014 Introduction The objective of the Naked Egg Lab is to soak the egg in a solution and determine if that solution is isotonic, hypertonic, or hypotonic in relation to the egg. A solution is a “mixture of two or more substances in which the molecules of the substances are evenly distributed” (Miller/Levine 2000). The substances in a solution are solutes, “the substance that is dissolved” (Miller/Levine 2000), and solvents, “the substance in which the solute dissolves” (Miller/Levine 2000).

We had the Biology Department staff put the 3 petri dishes in the incubator at 37 degrees Celsius for a 24 hour period. After that they were kept refrigerated an additional 6 days. One plain agar plate should have been incubated as well to provide a control for our experiment, but it was not. Results Human lips, the soil outside of QCC, and a toilet seat were all tested for bacteria content. All three of the things tested: human lips, soil, and toilet seat had some bacteria content that grew.

Broken EggsProblem Statement: The situation in this assignment is a farmer is taking her eggs to the market in her cart, but along the way she drops her eggs cracking most of them. So, then she goes to her insurance agent to ask how many eggs she had. The insurance agent wasn’t sure, but she remembers she package the eggs in a certain pattern. This certain pattern was when she put the eggs in a group of seven there was no egg left over, but when she put them groups of 2,3,4,5, and 6 there was always one left over with those #s. So, are there more than one possibility in this situation?Process: Firstly, I tried to find multiples of seven, and I tried to find multiples of seven because, in the problem sentence it said that when the lady put the eggs in groups of seven it had no eggs left over. But, in those multiples of seven I tried to find if I divided the number by 2,3,4,5,

Foodborne illness, or food poisoning, happens everyday in the U.S. and it is estimated that 48 million people are affected by it every year. Of these 48 million, 128,000 end up in the hospital and 3000 of them die from foodborne pathogens (Tucker, 2014). Foodborne illnesses can be caused by biological, chemical, or physical contaminants. The biological contaminants consist of bacteria, viruses, parasites, and fungi. Chemical contaminants are pesticides, cleaning supplies, and toxic chemicals. Physical contaminations are dirt, glass, wood, splinters, stones, hair, jewelry, and metal shavings (Tucker, 2014). Salmonella, a bacterium, has been the most common reported cause of food poisoning. Salmonella is most commonly exposed to humans through animal feces and it is usually from animals that give us beef, poultry, and dairy products. People who do not wash their hands after being around animals can also transmit salmonella into our food. The symptoms of Salmonella are abdominal cramps, diarrhea, nausea, vomiting, and fever (Tucker, 2014). The symptoms will usually resolve on their own in healthy people but may become life threatening in those with compromised immune systems. In order to prevent Salmonellosis, raw eggs should be avoided, as well as undercooked meat, shellfish, and unpasteurized milk and juice (Tucker, 2014). It is also important to always practice hand hygiene before handling any uncooked food products. Escherichia Coli, otherwise known as E. coli, is

The hypothesis of this experiment, the organism responsible for spoiling would be of the Pseudomonas genus can be confirmed with a relatively high degree of confidence. A very accurate match to Pseudomonas azotoformans was observed when comparing the data from the Sanger sequencing of the isolated DNA to the BLAST database. This correlates with published research which identifies this microorganism as a prominent grey milk causing species (Cite). However, in order to acquire full confidence in this acquisition, Koch’s postulates should be implemented. The isolated bacteria should be inoculated into an uncontaminated milk sample and observations should be made to examine if the grey milk defect reoccurred. This would confirm that Pseudomonas

Have children stand side by side with their "eggs" (beanbags or Hacky Sack-style foot bags) on top of their feet. Players try to shuffle across the room without dropping their "eggs." If the egg is dropped the person who dropped it must move to the side and do a series of pushups, jumping jacks, and sit-ups (all 10 times each). Once they have completed the series they become a penguin shuffling around with their egg.

After you dressed, did you stop for breakfast? Did you have orange juice, or perhaps scrambled eggs, or maybe a bagel with cream cheese? The only reason you can be sure that your orange juice, eggs and cream cheese are not contaminated with bacteria that would make you sick is that public health regulates the safety of your food supply. We also teach and promote safe food handling practices that kill bacteria and help you and those who handle your food from contaminating it.

When purchasing pasteurized eggs, I would also make sure that they bear the United States Department of Agriculture (USDA) inspection label. When eggs are pasteurized they are quickly heated and maintained at the least required temperature for a certain amount of time. This process will kill salmonella. During this process it will not cook the eggs nor will it affect the color. In addition, the flavor of the egg or it nutritional value will not be altered.

Gram-negative bacteria cause numerous diseases and can affect all classes of poultry. Moreover, some of these bacteria can cause life-threatening complications and

Common illnesses that can occur are salmonella and trichinosis poisoning resulting from improper handling of chicken, eggs or pork (Jardin, 2009, para.2). Diseases such as: campylobacteriosis, cholera, and listeriosis also make the list of illnesses (Jardin, 2009, para.1). These diseases are the versions of food poisoning, which can be life-threatening. According to the World of Health article published in 2007,
