- PublicationDetermination of total microorganisms count and vibrio species in crustaceans(2017-05)Lutfi, Nurul Allia Ezzati MdVibrio microorganisms are very common in coastal environments, thus they are usually present in seafood. The most prevalent Vibrio microorganisms discovered in seafood, particularly crustaceans are V parahaemolyticus, V cholerae, and V vulnificus. However, currently in Malaysia, there is no set standard for the permissible limit of Vibrio microorganisms in crustaceans. Hence, the aim of this study was to determine their presence in crustaceans available in Malaysia. The methodology being utilized in this study was as according to Bacteriological Analytical Methods from the Food and Drug Administration (FDA). For this study, 10 different species of crustaceans were purchased from markets around Kota Bharu, Kelantan and were analyzed both for the total microorganisms count and Vibrio microorganism's profile. The results had shown that Metapemeopsisbarbata, or sand prawn was the type of crustaceans which had the highest microorganisms count at 1.33x 1010cfu/g as compared to the other tested crustaceans. 30% of the samples tested had a higher microorganisms count than the established standard, in which that the limit for total microorganisms count in fishery products stated by Ministry of Health Malaysia is at most at 106cfu/g. This may posed a threat to those who are unaware of the risk that may be present. Around 60% of the crustaceans harboured both V parahaemolyticusand V cholerae, which could lead to health complications if prepared inappropriately, particularly to those with compromised immune system. In conclusion, by making this information accessible to the general population, the incidence of food poisoning due to Vibrio microorganisms could be decreased and proper handling of crustaceans during preparation could be widely practiced.

- PublicationMicrobial contaminations on hands among visitors at critical units of Hospital Universiti Sains Malaysia(2017-06)Mazlan, Nurul AimiVisitors’ hands can be contaminated with pathogenic microorganisms that are dangerous to the vulnerable and immunocompromised critical unit patients. Inadequate cleaning of hands could carry the pathogenic organisms and transmit disease to one self as well as to the visited patients. This study was done to determine the presence of Escherichia coli (E. coli) and Methicilin-resistant Staphylococcus aureus (MRSA) contamination on hands among visitors at critical units with respect to their hand hygiene practices. A total of 52 visitors were selected into this study using grab sampling. Questionnaire gathering information on hand hygiene were distributed among the visitors prior their dominant hand swabbing. Identification of the microorganisms were conducted by gram staining, biochemical tests, disc diffusion test and selective agar medium. It was found that 98.1% (n=51) of their hands were contaminated by microorganisms (3.87xl014±1.65xl013 CFU/ml). E. coli was isolated MRSA found. Only 40.4% (n=21) visitors performed hand hygiene before meeting with patients. There was marginally significant association between washing hands before meeting patients and the presence of E. coli (p=0.052). A significant difference was obtained in Staphylococcus aureus contamination among those who perform hand washing before patient contact (p=0.014). As a conclusion, a higher bacterial contamination on hands might be contributed by inadequacy of proper hand hygiene practices as it was unacceptably low (less than 50%), despites no MRSA was found. Thus, behaviour and attitudes regarding hand hygiene among visitors need to be improved by multidisciplinary approach.
- PublicationKnowledge, attitude and practices of prophetic diet (dates) among Islamic and health sciences student background(2018-06)Abdullah, Nor Faizatul NajwaThe purpose of this cross-sectional study was to investigate the level of Knowledge, Attitude and Practice (KAP) on date fruit among final year degree KIAS students (Islamic background) and final year PPSK USM students (Health Sciences background). A total of 207 respondents from USM (with mean age: 23.14 ± 0.77) and 96 respondents from KIAS technique. A structured questionnaire consisted of sociodemographic information, KAP and physical characteristics question used to assess the data among Health Sciences background and Islamic background. Result from this study showed respondents from Health Sciences background recorded higher percentage of normal body weight compared to Islamic background respondents which is 44.0% and 36.5% respectively. However, respondents from Islamic background have higher percentage of underweight (35.4%) compared to respondents from Health Sciences background only 27.5%. Besides, respondents from Health Sciences background also have higher percentage of overweight (21.7%) compare to Islamic background respondents which is 14.6%. For obese, Islamic background respondents recorded higher percentage compare to Health Sciences background which is 13.5% and 6.8% respectively. Result from this study showed that 88.5% of the respondents from Islamic background (KIAS) have high level of knowledge on dates compare to Health Sciences background (USM) which is only 59.4%. For level of attitude on date fruit among this two population, study found that 65.6% of the respondents from Islamic background have high level of attitude toward dates compared to 32.4% of respondents from Health Sciences background. Majority of the respondents from Health Sciences background (96.1%) and Islamic background (94.8%) consumed dates during the last Ramadhan. However during outside Ramadhan, 27.1% and 14.6% respondents from Health Sciences background and Islamic background respectively never consumed dates. From overall data in this study, it seems that the students from Islamic background (KIAS) have good level of knowledge, attitude and practices compare to Health Sciences background (USM).
- PublicationAssessment on knowledge, attitude & belief on dietary calcium & dairy intake among undergraduate students, health campus, Universiti Sains Malaysia(2018-06)Bohari, HaziqahCalcium intake has been recognised to reduce the incidence of osteoporosis in humans. Calcium is important for humans but deficient in diets of young adults. This study was conducted to identify the level of knowledge, attitude & belict in calcium intake among university students at Health Campus, Universiti Sains Malaysia, Kelantan. Cross-sectional study was conducted on 158 students aged 18 to 32 years old. Convenience sampling method used to select respondents around the campus area. A modified questionnaire was used to assess the level of knowledge, attitude and beliefs of the respondents, while the Food Frequency Questionnaire (FFQ) was used for calcium intake. Based on Recommended Nutrient Intakes (RN1) for Malaysia, respondents were categorized into two groups, high calcium intake (>800 mg / day) and low calcium intake (<800 mg / day). Analysis of 84.8% of respondents has been identified to have low levels of calcium intake where male respondents had higher levels of calcium intake than female. More than half of the participants had a low knowledge of 58.9%. However, their attitude and belief were positive respectively to 65.8% and 65.2%. There is no significant association found between the level of knowledge, attitude and belief with level of calcium intake. Furthermore, there is no significant association found between the level of knowledge, attitudes and belief based on gender. Study also found that there was no significant association between gender and level of calcium intake (p = 0.211). In conclusion, although no significant association found in knowledge, attitude and belief was identified, it still can be a factor that contributes to calcium intake of participants. Intervention program such as health education can be implemented to improve the knowledge, attitude and belief of university students and increase calcium intake.
