Analys av ismaskiner i olika verksamheter : en jämförelse mellan traditionell dricksvattenanalys och ATP-analysBurström, Frida January 2018 (has links)
Food businesses must be able to ensure that they deliver safe food to the customers. Previous studies have shown that sufficiently cleanliness in ice machines are not always achieved. Since ice can be consumed the consequence of contaminated ice is that the food safety is not guaranteed. The aim of the study was to investigate bacterial contamination in ice machine in different food businesses with either an ordinary way to analyse ice as drinking water sample or with a newer and faster method measuring adenosine triphosphate (ATP). With the ATP-method a result will be obtained within about 30 seconds. In this study tests on the ice machines were made for microbiology testing the water, testing the surfaces with ATP and testing the water with ATP. Half of the result from the microbiology tested ice had results beyond the limit value. The categories of food businesses had problems, but the food stores had the highest proportions of unsatisfactory results. The result of the samplings shows a correlation between the parameters total microorganisms and ATP samples of water. The study also shows problems with the limits put up to the ATP-measuring and translating them to the testing for drinking water.
