Food poisoning is an illness that is caused due to the consumption og eating food that is contaminated. The food standard agency has estimated that in UK each year 5.5 million people get affected by food poisoning (NHS, 2013). Ready to eat food are defined as foods that are produced by the manufacturer for direct human consumption with exclusion of any need for cooking or any processing. In the UK, salad consumption has increased widely; salads are considered as safe by the consumers. In recent years it has increased both in quantity and variety. Due to the governments 5- A- Day campaign, the trend in ready to eat salads has increased widely in UK (Little et al, 2008). Salads have become the main meal favourite of people nowadays, with the addition and accomplishment of cheese, 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.

Fourth week : During this week, I will be collecting results from the third week and plating the colonies onto different selective media (Oxford and PALCAM agar)
Fifth week: During this week, I will be collecting results from fourth week and will restreak the colonies into a non selective medium ( Tryptic soy agar)
Sixth week: during this week, I will be collecting results from fifth week and conducting different biochemical testing which include gram stain, catalase, acid production of carbohyrdrate test and API Listeria.
Seventh week: This week will be used for the collection of the biochemical testing from the sixth week.
Eighth week : this week will be used for the data analysis of the results. This will be done with the help of the SPSS software.

Isolation was successful. One colony of each unknown bacteria was transferred to an agar slant for growth. The agar slants were stored at room temperature over the weekend so that they would not grow too much.

    I also inoculated a tryptic soy broth (TSB), a nutrient gelatin deep, a motility agar deep, a fluid thioglycollate medium (FTM) tube, and a TSA plate with my unknown culture. All of these inoculated media were incubated until the next class period (about 48 hours). Then when I came to class most of my inoculated tubes and my streak plate appeared to have growth. The next step I took was making a gram stain to determine the gram reaction and cellular morphology of my unknown. I used my working slant to do this, after careful examination of the gram stain, I learned that my unknown was a gram-positive bacterium. I then preceded by making a negative stain to see the size of the cells of my unknown bacteria. The cell shape was cocci and the cells occurred in clusters of tetrads. After discovering that my unknown bacteria was gram-positive cocci, I turned to page 207 of the lab manual to narrow down my options, there was only four out of the gram-positive list that were

    What is Foodborne Illness? According to a medical dictionary, foodborne illness is an acute gastrointestinal infection caused by consuming food contaminated with pathogenic, bacteria, toxins, viruses, prions or parasites. Such contamination was caused by improper food handling, preparation or storage of food.

  • Bahrain Food Control Systems Review

    739 Words  | 2 Pages

    A SWOT analysis of the food control system in Bahrain revealed that certain strengths and weaknesses are inherent in the system. In addition to the weaknesses and the strengths, there are threats that would negatively affect the system if not prevented or brought under control. Nevertheless, the there are opportunities available for responding to the threats, making the Bahrain food control systems more efficient and effective. It is therefore important that some or all of these strengths, opportunities, threats, and weaknesses are reviewed. Conspicuous among the weaknesses is the fact that limited resources are available for the agencies and the personnel employed in the Bahrain food control system. Related to lack of resources is the lack of skills and competencies in applying modern techniques, more so in microbiological and chemical analysis. The second weakness of the Bahrain food control system is that most of the laws and regulations on food safety and control are not based on risk- or science-based analysis. In other words, the laws could be outdated and irrelevant in comparison with the latest mechanisms by which pathogens and other contaminants affect foodstuffs (Nestle, 2007). Furthermore, Bahrain lacks the technical expertise or competent enough personnel who could assess the effectiveness and the applicability of their food control laws.

Food is wasted through many different ways at farms, grocery stores, and in homes. Over 40% of the food in the United States, specifically, goes to waste and 97% percent of this waste goes straight to landfills. The main issue with food waste is that the majority of food is being wasted unnecessarily. In stores, food is often thrown out because it does not meet specific standards that dictate what may be desirable to consumers. This issue of food picking is important as foods are not always being thrown away because they have gone bad, but because they have appearances that do not seem attractive. If we hope to lessen the environmental impact we have as a result of the mass
