This is primarily because two sprouting facilities in two states were linked with the implicated alfalfa sprouts and only one lot of seeds from Idaho State was common to Michigan and Virginia. Therefore, the likely point of contamination include during growth or harvesting, seed processing, in storage, or during transportation of the food. This implies that the identification of the actual point of contamination requires collection of more information on each of these steps.
Question 17:
The results of inspection of the alfalfa fields indicated that the three possible source of contamination include cattle manure, deer feces, and irrigation water. Generally, cattle are the basic reservoir for E. coli O157:H7 while other animals like deer can either be carriers of or become infected by the bacteria. Therefore, inspecting the alfalfa fields and harvesting process may require consideration of the site of the fields, soil, fertilizer, pesticides, irrigation water, harvesting and processing equipment, storage containers and rooms, and shipping trucks.
Question 18:
Generally, dealing with the issue of seed sprouts as a high risk mechanism for foodborne illness is a relatively difficult task that requires consideration of short- and long-term measures when suggesting the most appropriate intervention or control measures. Some of these short-term and long-term measures under consideration include the immediate problem with the implicated lot of seed and the wider issue of seed sprouts as channels for pathogenic agents respectively. However, few options exist with regards to intervention or control measures because of the nature of sprout production and the present inability to remove contamination.
Some of the intervention / control measures I would suggest at this point include ongoing applied research to identify ways to successfully decontaminate the seeds or sprouts. Secondly, the public should be educated regarding the risks of sprouts while individuals...
Question 14 The main criteria that should be considered is the type of infection based on microbiological evidence. Additionally, it is important to determine whether or not there was onsite mishandling which may have led to E. coli being present on particular products. The scope of the outbreak would also be important, as it would show either a local outbreak, or a more widespread one that would indicate a larger producer. Question
DISCUSSION QUESTIONS Clinical Case Study Discussion Questions1. What is the most likely causative microorganism in this outbreak?The most likely causative microorganism in this case is Listeria monocytogenes. This pathogen has been described by Osek, Lachtara and Wieczorek (2022) as �a gram-positive, facultative intracellular rod bacteria...� (413). As the authors further indicate, this pathogen happens to be responsible for a serious infection called listeriosis which is associated with the consumption of
Microbiology & Spontaneous Generation Microbiology is the study of microbes that are practically invisible to the human eye. Although microbes are usually associated with causing and aiding disease, they are essential organisms in the ecological world. They allow for life to thrive and are of great interests for food, scientific, and medical industries (Black, 2008). The term microorganism encompasses bacteria, protozoa, fungi, archaea, parasites, algae, prions, and viruses (Nester, Anderson, &
Microbiology Please develop your own strategy for TB prevention. The Source of the Disease As mentioned in the above question, tuberculosis is a complex disease that has ravaged society for centuries. Whereas in the Western countries, it is now possible to receive treatment and become healthy despite contacting tuberculosis, there are areas of the world where, due to societal or environmental and political problems, it is difficult both to seek and obtain care,
Instituting these measures showed that the company was vitally interested in not only maintaining the company's integrity, professionalism and reputation but also in ensuring that the problems never arose again. Other methods initiated by the company included a program that would test heat cleaning of apples that would kill the bacteria while not affecting the taste of the apples. The company also introduced a process of cleaning and decontamination called
Air traffic has continued to increase and it now constitutes a considerable proportion of the travelling public. The amount of long-hour flights has increased significantly. Based on the International Civil Aviation authority, air traffic can be anticipated to double amid till 2020. Airline travel, especially over longer distances, makes air travelers vulnerable to numerous facets that will impact their health and well-being. Particularly, the speed with which influenza spreads and
