Introduction: Ice can be contaminated by pathogenic bacteria. This study aimed to identify critical points in iced beverage production and distribution lines to examine the presence of pathogenic bacteria in a beverage and its processing environment, as well as when water and ice used as main ingredients. Methodology: The critical points were determined using the principles of Hazard Analytical Critical Control Point (HACCP) to analyze each processing and distribution step from the survey. Samples collected from the points of concern based on the critical points that were found were tested for pathogens by conventional method and molecular method using primers and polymerase chain reaction (PCR). Results: Escherichia coli was found in 6.34% of samples, and 0.7% of them were confirmed as enterotoxigenic Escherichia coli (ETEC) by PCR. Vibrio cholerae was found in in 0.7% of water samples used to make iced beverages and in ice production, as well as in 2.12% of distribution and production tools. Salmonella Typhimurium was found in 1.4% of water samples used to make ice and ice products. Staphylococcus aureus was found in 2.02% of the surfaces of ice distribution and production tools and in 5.05% of production and distribution workers' hands. S. aureus counts ranged from 2.4×10 2 -3.5×10 2 colonies/100 cm² surface area and 1.9×10¹ -3.7×10 2 colonies/workers' hands. Conclusion: Control on many critical points in iced beverage processing and distribution is required so that the beverages are safe for consumption.
All samples, except water, swabs of food handlers and mortars, were taken with the same weight at a different spot to collect approximately 200g and put into containers aseptically. For water, samples were collected from the tap, well, and refilled drinking water (originating from depots). The hands of food handlers and mortars were swabbed prior to preparing fried chicken.
Background: Besides their mutagenic, carcinogenic, and teratogenic effects, Aflatoxins (AFs) also act as the main contributor to hepatocellular carcinoma (HCC) which is known as the most common primary liver cancer worldwide. The main aim of this study was risk estimation of HCC due to exposure to aflatoxins in maize from Yogyakarta, Indonesia.
Methods: As a model, maize samples were taken from Yogyakarta province, Indonesia. The present research was conducted by risk assessment approach which includes hazard identification, hazard characterization, exposure assessment, and risk characterization. The aflatoxin analysis was performed using High Performance Liquid Chromatography method and the secondary data was taken from the province report.
Results: The mean total AF in raw material, dried maize chips, and fried chips were 46.58, 17.58, and 13.24 ppb, respectively. The raw material clearly had higher level of all AF types. The mean of contamination of total AF in raw material (46.58 ppb) exceeded the standard level (20 ppb), while the other products were not more than standard level. The yearly maximum exposure to AFB1 ranged from 85.07 to 92.80 ng/kg body weight per day. The estimation of HCC cases ranged from no case to 43 cases per year.
Conclusion: Preventive hygienic efforts are needed to reduce AF contamination and risk of HCC in maize consumed in this region of Indonesia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
