Listeria monocytogenes Introduction Listeria monocytogenes, a motile, gram-positive rod, is an opportunistic food-borne pathogen capable of causing listeriosis in humans. Listeriosis includes manifestations of septicemia, meningitis, pneumonia, and encephalitis. L. monocytogenes is also implicated in miscarriages, stillbirth, and premature birth for pregnant women. L. monocytogenes is a tough bacterium resistant to freezing, drying, and heat; most strains have been shown to be pathogenic. It
Introduction The genus Listeria contains six species, two of which are considered pathogenic: Listeria monocytogenes and Listeria ivanovii. L. monocytogenes is the only species that is associated with listeriosis in humans (1). L. monocytogenes is a Gram-positive rod, facultative anaerobe; at room temperature, it exhibits tumbling motility due to peritrichous flagella (1). It has an optimal growth temperature of 32-35oC, but L. monocytogenes can grow between 0-45oC, pH 4.4-9.4, and a water activity
Blue Bell Creameries Listeria Crisis An organization’s quick response to crisis and effective crisis management are both vital to their sustainability. Blue Bell Creameries faced crisis in April, when a bacterial contamination caused operations to halt world-wide. Crisis management for this company has involved much more than finding and fixing the issue. This company has responded to financial loss, legal ramifications, employee impact, and perhaps the most crucial – public perception. About
pasta, couscous etc. (Food safety agency, 2014) This study is based on testing of refrigerated ready to eat salads which includes both fresh cut and bagged salads. In this study the main bacterium that is going to be determined are Listeria spp. Specifically Listeria monocytogenes. The study is aimed to establish the microbiological quality of ready to eat fresh cut salads and bagged salads from different catering and retail premises. RESEARCH BACKGROUND The common causes of food poisoning are bacteria
People are sick, and it is because of listeria. Jeni’s Splendid Ice Cream is doing all they can do to help fight the listeria outbreak before it is blown up, more than it already is. Jeni’s Ice Cream is safe to eat because they have no deaths from their produce. The news and consumers have blown this outbreak up way more than it needed to be because they didn’t realize that Jeni didn’t have contaminated produce that they could consume. Jeni’s Ice Cream should be doing as well as it used to because
The Effect of Listeriosis in Ovine Vs. Bovine Introduction Listeria, also referred to by the name Listeriosis, is an infection that is caused by eating contaminated food containing the bacterium Listeria Monocytogenes. This particular disease can affect not only animals, but also older adults, pregnant women, newborns, and adults with weakened immune systems. When looking at these bacteria under a microscope, they appear to be small and rod-like and can sometimes be seen arranged in short
People are sick, and it is because of Listeria. Jeni’s Splendid Ice Cream is doing all they can do to help fight the Listeria outbreak before it becomes more blown up than it already is. There has been skeptulations in the media about if Jeni’s Splendid Ice Cream is safe to eat or if the consumer will get Listeria. Jeni’s Ice Cream is safe to eat because they have no deaths from their produce. The news and consumers have blown this outbreak up a considerable amount more than it needed to be because
effective treatment which further underscores the urgent need for the development of alternative therapeutic options (Mohamed et al., 2014). This scourge is further compounded by intracellular zoonotic pathogens, such as Mycobacterium, Salmonella, Listeria, and Brucella that reside and thrive inside mammalian cells (Seleem et al., 2009a, 2009b; Nepal et al., 2015). Treatment of infections caused by these intracellular pathogens is very challenging because most antibiotics are unable to access intracellular
video, he emphasized the history of the company, a commitment to get it right, and sympathy for lost ice cream. Most importantly, he referred to the Listeria incident as a "heartbroken situation." In addition to the video, Blue Bell utilized its website as an information portal on Listeria. The website provided information on the side effects of Listeria, press releases, the statement by Paul Cruse, as well as a "Commitment to You" page reiterating its commitment to production quality and
common, but fewer than 20 of the many thousands of different bacteria actually are the culprits. More than 90 percent of the cases of food poisoning each year are caused by Staphylococcus aureus, Salmonella, Clostridium perfringens, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus, Bacillus cereus, and Entero-pathogenic Escherichia coli. These bacteria are commonly found on many raw foods. Normally a large number of food-poisoning bacteria must be present to cause illness. Therefore
food poisoning, patients can see blood in their vomit or diarrhea. In extreme cases of Escherichia coli food poisoning, kidney failure can be experienced. There can be death from food poisoning, but it is rare (Lowinger 1). Like Escherichia coli, Listeria and Campylobacter can have some very extreme cases that can potentially cause major
Microbe is a microorganism, that is known as a bacterium that cause diseases or fermentation. Microbes can have a powerful impact on each individual’s health and well-being. The role of antibiotics is through the influence of things that the cells of bacteria have. ("Microbe", 2017, p.2). This essay will briefly outline a range of common microbes that affect human health and discuss the benefits and risks of antibiotics, and discuss a range of therapeutic uses of microbes. For many years antibiotics
farmers were arrested over a deadly Food Bourne Illness, listeria. In 2011 the FDA said that the Janson’s farm led to the listeria outbreak that killed thirty three people. Also, the FDA said that people in twenty eight different states ate the contaminated fruit, and one hundred and forty seven people were hospitalized. In Ohio, A woman named Constance George filed a lawsuit against Dole Fresh Vegetables, after a salad mix tainted with listeria put her mother, Kiki Christofield, in a coma. She bought
significant and important public health problems in United States causing numerous illnesses, hospitalizations and deaths of people. Centre for Disease control and Prevention report Nontyphoidal Salmonella, norovirus, Campylobacter spp., Toxoplasma gondii, Listeria monocytogenes, Clostridium perfringens, Escherichia coli O157 and Staphylococcus aureus as the major food borne pathogens significant in US. CDC estimates that roughly 1 in 6 peoples got sick with 128, 000 hospitalizations and 3,000 deaths each year
spread the bacteria. However, other meningitis causing bacteria are not spread person to person, but can cause disease due to the certain risk factors, such as, a weak immune system or head trauma. It should be noted, that one can get meningitis from Listeria monocytogenes by eating
need for several vitamins and minerals, such as folate and iron. Also of importance is adequate calcium intake and avoidance of excessive mercury (some fish e.g. flake) and vitamin A(e.g. liver products) and alcohol as well as potential sources of listeria (e.g. soft cheeses and cold/undercooked meat) as they can be harmful to the developing foetus.[1, 2, 5] In order to highlight these required nutritional intake changes during pregnancy and the consequential changes to dietary behaviours I attempted

Maple Leaf Food’s Code of Business Conduct (Appendix A) talks about management’s commitment to ensuring Maple Leaf and its employees demonstrate the highest standards of ethics and integrity in all business activities (Henry, 2013). The numerous reports and studies that have been undertaken since the listeria outbreak demonstrate how Maple Leaf’s response was able to build the
THE HEALTH RISKS ASSOCIATED WITH THE USE OF FEEDLOTS IN AMERICA Chanel Bailer AP Capstone Mrs. OT Period 5 Word Count: 1432 Most American beef is raised on feedlots, to provide a lot of beef in a short period of time. These feedlots are crowded, which can cause the corn-fed cows to breed diseases that could be potentially harmful to the consumers. Feedlot owners have to give cows antibiotics to try to prevent the spread of diseases from animal to animal. Yet, sometimes these antibiotics
