    PMID: 20208424
    Recently, many cases related to viral gastroenteritis outbreaks have been reported all over the world. Noroviruses are found to be leading as the major cause of outbreaks of acute gastroenteritis. Patients with the acute gastroenteritis normally found to be positive with norovirus when stools and vomit were analyzed. This paper reviews various activities and previous reports that describe norovirus contaminated in various food matrixes and relationship between food handlers. Lately, a numbers of norovirus outbreaks have been reported which are involved fresh produce (such as vegetables, fruits), shellfish and prepared food. Food produces by infected food handlers may therefore easily contaminated. In addition, food that required much handling and have been eaten without heat treatment gave the high risk for getting foodborne illnesses. The standard method for detection of norovirus has already been available for stool samples. However, only few methods for detection of norovirus in food samples have been developed until now.

    Toh PS
    Int J Environ Health Res, 2002 Dec;12(4):311-6.
    PMID: 12596745 DOI: 10.1080/0960312021000056447
    This study investigates the practices and knowledge of a Control Authority dealing with the environment and the safety and control of hawker foods. Experience and background education are used as likely determinants of food safety practices and knowledge of the control authority. A total of 60 questionnaires were distributed to the Health Inspectors (HIs) in the Hawkers' and Health Departments, City Hall, Kuala Lumpur. The return rate was 93%. The structured questionnaire contained 14 main food safety practices and knowledge constructs. Significance was found pertaining to knowledge of HIs with different experience backgrounds but experience was not demonstrated to impact on practices of HIs. However, education was noted to have significantly but inconsistently influenced certain Practices and Knowledge scores of HIs. A Pearson bivariate coefficient characterised an association between food safety practices and knowledge of the control authority. The findings: (1) highlight the actual shortcomings in the staff resources relating to environmental health, food safety, foodborne illnesses and their control, and (2) provide information on the control aspect within the hawker micro-industry with the view of protecting the public from health hazards arising from the hawkers' practices and consumption of hawker foods.

    MyJurnal
    According to the World Health Organisation (WHO), globally 600 million people suffer
    from food-borne diseases (FBD), and 420,000 people die as a result. The European Food
    Safety Authority (EFSA) has stated that FBD are linked to the food industry, with the
    most common means of transmission being due to poor food handling and hygiene by
    food handlers working in the food industry. The aim of this research was to investigate the
    effectiveness of mandatory food handler training programmes (FHTP) to prevent FBD in
    Malaysia and Ireland. To do this, the FHTP existing in Malaysia and Ireland were
    analysed, in addition to the legislation they fall under in each respective country.
    Effectiveness was determined by investigating the level of food safety knowledge (FSK)
    and food safety practices (FSP) of food handlers in Malaysia and Ireland. A systematic
    literature review (SLR) and a narrative literature review (NLR) were conducted for this
    research. The SLR was based on the PRISMA diagram, using the Confidence in the
    Evidence from Reviews of Qualitative research (CERQual) approach to evaluate the
    studies used for this research. A total of 8 Malaysian studies and 1 Irish study were used to
    determine the level of FSK and FSP of food handlers in each respective country, to
    examine the effectiveness of FHTP. The results of the studies used for this research have
    depicted overall good FSP and FSK of food handlers in Malaysia and Ireland; yet trends
    continue to show that food handlers are one of the biggest contributors to FBD,
    demonstrating that FHTP are not effective in preventing FBD. The findings from this
    research highlights that although these trainings can be an effective tool to prevent FBD, if
    they are not executed correctly, food handlers will continue to contribute to FBD.

    Teh SS, Hock Ong AS, Mah SH
    J Oleo Sci, 2017;66(11):1183-1191.
    PMID: 29093377 DOI: 10.5650/jos.ess17078
    The environmental impacts of palm oil mill effluent (POME) have been a concern due to the water pollution and greenhouse gases emissions. Thus, this study was conducted to recover the value-added products from POME source before being discharged. The samples, before (X) and after (Y) the pre-recovery system in the clarification tank were sampled and analysed and proximate analysis indicated that both samples are energy rich source of food due to high contents of fats and carbohydrates. GCMS analysis showed that the oil extracts contain predominantly palmitic, oleic, linoleic and stearic acids. Regiospecific analysis of oil extracts by quantitative 13C-NMR spectroscopy demonstrated that both oil extracts contain similar degree of saturation of fatty acids at sn-2 and sn-1,3 positions. The samples are rich in various phytonutrients, pro-vitamin A, vitamin E, squalene and phytosterols, thus contributing to exceptionally high total flavonoid contents and moderate antioxidant activities. Overall, samples X and Y are good alternative food sources, besides reducing the environmental impact of POME.

    PMID: 27168760 DOI: 10.1186/s12995-016-0112-y
    BACKGROUND: Marine stings and envenomation are fairly common in Malaysia. Possible contact to various marine life occurs during diving, fishing and food handling. Even though majority of fish stings are benign, there are several venomous species such as puffer fish, scorpion fish, lionfish, stingray and stonefish that require urgent medical treatment. Stonefish is one of the most venomous fish in the world with potential fatal local and systemic toxicity effects to human.

    CASE PRESENTATION: We reported a case of stonefish sting complicated with impending compartment syndrome.

    CONCLUSIONS: Medical staff should be alert about the possibility of this potential emergency in standard management of stonefish stings.

  6. Fulltext Comparison between airborne ultrasound and contact ultrasound to intensify air drying of blackberry: Heat and mass transfer simulation, energy consumption and quality evaluation
    Tao Y, Li D, Siong Chai W, Show PL, Yang X, Manickam S, et al.
    Ultrason Sonochem, 2021 Apr;72:105410.
    PMID: 33341708 DOI: 10.1016/j.ultsonch.2020.105410
    This study aimed at investigating the performances of air drying of blackberries assisted by airborne ultrasound and contact ultrasound. The drying experiments were conducted in a self-designed dryer coupled with a 20-kHz ultrasound probe. A numerical model for unsteady heat and mass transfer considering temperature dependent diffusivity, shrinkage pattern and input ultrasonic energies were applied to explore the drying mechanism, while the energy consumption and quality were analyzed experimentally. Generally, both airborne ultrasound and contact ultrasound accelerated the drying process, reduced the energy consumption and enhanced the retentions of blackberry anthocyanins and organic acids in comparison to air drying alone. At the same input ultrasound intensity level, blackberries received more ultrasound energies under contact sonication (0.299 W) than airborne sonication (0.245 W), thus avoiding the attenuation of ultrasonic energies by air. The modeling results revealed that contact ultrasound was more capable than airborne ultrasound to intensify the inner moisture diffusion and heat conduction, as well as surface exchange of heat and moisture with air. During air drying, contact ultrasound treatment eliminated the gradients of temperature and moisture inside blackberry easier than airborne ultrasound, leading to more homogenous distributions. Moreover, the total energy consumption under air drying with contact ultrasound assistance was 27.0% lower than that with airborne ultrasound assistance. Besides, blackberries dehydrated by contact ultrasound contained more anthocyanins and organic acids than those dried by airborne ultrasound, implying a higher quality. Overall, direct contact sonication can well benefit blackberry drying in both energy and quality aspects.

    Tang MY, Cheong YM, Zainuldin T
    Med J Malaysia, 1994 Sep;49(3):217-22.
    PMID: 7845269
    From April 1992 to September 1992, 280 samples of 10 different fresh vegetables, bought from four different market outlets in Kuala Lumpur were examined for the presence of Listeria spp. Most of the market produce were locally grown with the exception of carrots. The isolation procedure was based on the Food & Drug Administration method (modified) used for the detection of Listeria spp. Isolation media used were Listeria Selective medium and LiCl- phenylethanol-Moxalactam agars. The identification of isolates was by means of conventional biochemical tests and API Listeria identification system. Five out of the 280 samples showed Listeria contamination, Listeria monocytogenes was isolated in lettuce, sengkuang (Pachyrrhizus erosus) and selom Oenanthe javanica) and Listeria innocua was isolated from sengkuang (Pachyrrhizus erosus) and pegaga (Hydrocotyle asiatica).

    Tan, S.L., Cheng, P.L., Soon, H.K., Ghazali, H., Mahyudin, N.A.
    International Food Research Journal, 2013;20(1):71-76.
    MyJurnal
    A study was conducted to determine personal hygiene knowledge among 25 food handlers at 12 selected primary schools in Klang Valley area, Selangor, Malaysia. A qualitative approach using in-depth interviews was employed and respondents were selected by a convenience sampling. The results showed that the respondents had basic knowledge on personal hygiene practices, mainly on hand washing (30.7%) and glove use (18.7%). The food handlers (90%) practiced various good hand washing practices, with only 36% did not practice washing hands after eating or drinking. Most respondents (>70%) practiced glove use, however more than 50% did not wash hands with every glove change, change gloves when change type of products and after preparing raw material. The study showed that the food handlers have basic knowledge one good personal hygiene practices. However, some discrepancies were revealed in the proper hand washing procedure. This study recommended good hand washing procedure to be reiterated among the food handlers. There is also an immediate need for continuous training among food handlers regarding good personal hygiene practices.

    Tan, S.L., Lee, H.Y., Abu Bakar, F., Abdul Karim, M.S., Rukayadi, Y., Mahyudin, N.A.
    International Food Research Journal, 2013;20(5):2973-2977.
    MyJurnal
    A total of 85 food handlers participated in this study to determine the hygienic status of their hands in primary schools located in the state of Selangor (Malaysia). Overall findings revealed that the fecal contamination and personal hygiene of the food handlers were well maintained with the range of mean bacterial counts from 0.18 to 0.47 log10 Colony Forming Units/cm2 during the three intervals of hand swabbing (before, during and after) preparation of ready-to-eat foods. However, the general indication of the microbiological quality (Aerobic Plate Count) was out of the standard (range of mean bacterial counts from 1.39 to 1.56 log10 Colony Forming Units/cm2) based on previous literature. This study highlighted that the food handler’s adherence to Good Manufacturing Practice and Sanitation Standard Operating Procedures was insufficient and suggested that attention should be emphasized on their practices at the intervals of school recess: before, during and after the preparation of ready-to-eat foods. In addition, there is also a need in the implementation of an effective HACCP program in Malaysia school foodservice operations.

  11. A physicochemical investigation of membrane fouling in cold microfiltration of skim milk
    Tan TJ, Wang D, Moraru CI
    J Dairy Sci, 2014;97(8):4759-71.
    PMID: 24881794 DOI: 10.3168/jds.2014-7957
    The main challenge in microfiltration (MF) is membrane fouling, which leads to a significant decline in permeate flux and a change in membrane selectivity over time. This work aims to elucidate the mechanisms of membrane fouling in cold MF of skim milk by identifying and quantifying the proteins and minerals involved in external and internal membrane fouling. Microfiltration was conducted using a 1.4-μm ceramic membrane, at a temperature of 6±1°C, cross-flow velocity of 6m/s, and transmembrane pressure of 159kPa, for 90min. Internal and external foulants were extracted from a ceramic membrane both after a brief contact between the membrane and skim milk, to evaluate instantaneous adsorption of foulants, and after MF. Four foulant streams were collected: weakly attached external foulants, weakly attached internal foulants, strongly attached external foulants, and strongly attached internal foulants. Liquid chromatography coupled with tandem mass spectrometry analysis showed that all major milk proteins were present in all foulant streams. Proteins did appear to be the major cause of membrane fouling. Proteomics analysis of the foulants indicated elevated levels of serum proteins as compared with milk in the foulant fractions collected from the adsorption study. Caseins were preferentially introduced into the fouling layer during MF, when transmembrane pressure was applied, as confirmed both by proteomics and mineral analyses. The knowledge generated in this study advances the understanding of fouling mechanisms in cold MF of skim milk and can be used to identify solutions for minimizing membrane fouling and increasing the efficiency of milk MF.

  12. Sonication reduces the attachment of Salmonella Typhimurium ATCC 14028 cells to bacterial cellulose-based plant cell wall models and cut plant material
    Tan MSF, Rahman S, Dykes GA
    Food Microbiol, 2017 Apr;62:62-67.
    PMID: 27889167 DOI: 10.1016/j.fm.2016.10.009
    This study investigated the removal of bacterial surface structures, particularly flagella, using sonication, and examined its effect on the attachment of Salmonella Typhimurium ATCC 14028 cells to plant cell walls. S. Typhimurium ATCC 14028 cells were subjected to sonication at 20 kHz to remove surface structures without affecting cell viability. Effective removal of flagella was determined by staining flagella of sonicated cells with Ryu's stain and enumerating the flagella remaining by direct microscopic counting. The attachment of sonicated S. Typhimurium cells to bacterial cellulose-based plant cell wall models and cut plant material (potato, apple, lettuce) was then evaluated. Varying concentrations of pectin and/or xyloglucan were used to produce a range of bacterial cellulose-based plant cell wall models. As compared to the non-sonicated controls, sonicated S. Typhimurium cells attached in significantly lower numbers (between 0.5 and 1.0 log CFU/cm2) to all surfaces except to the bacterial cellulose-only composite without pectin and xyloglucan. Since attachment of S. Typhimurium to the bacterial cellulose-only composite was not affected by sonication, this suggests that bacterial surface structures, particularly flagella, could have specific interactions with pectin and xyloglucan. This study indicates that sonication may have potential applications for reducing Salmonella attachment during the processing of fresh produce.

  13. Strawberry puree processed by thermal, high pressure, or power ultrasound: Process energy requirements and quality modeling during storage
    Sulaiman A, Farid M, Silva FV
    Food Sci Technol Int, 2017 Jun;23(4):293-309.
    PMID: 28595485 DOI: 10.1177/1082013216685485
    Strawberry puree was processed for 15 min using thermal (65 ℃), high-pressure processing (600 MPa, 48 ℃), and ultrasound (24 kHz, 1.3 W/g, 33 ℃). These conditions were selected based on similar polyphenoloxidase inactivation (11%-18%). The specific energies required for the above-mentioned thermal, high-pressure processing, and power ultrasound processes were 240, 291, and 1233 kJ/kg, respectively. Then, the processed strawberry was stored at 3 ℃ and room temperature for 30 days. The constant pH (3.38±0.03) and soluble solids content (9.03 ± 0.25°Brix) during storage indicated a microbiological stability. Polyphenoloxidase did not reactivate during storage. The high-pressure processing and ultrasound treatments retained the antioxidant activity (70%-74%) better than the thermal process (60%), and high-pressure processing was the best treatment after 30 days of ambient storage to preserve antioxidant activity. Puree treated with ultrasound presented more color retention after processing and after ambient storage than the other preservation methods. For the three treatments, the changes of antioxidant activity and total color difference during storage were described by the fractional conversion model with rate constants k ranging between 0.03-0.09 and 0.06-0.22 day - 1, respectively. In resume, high-pressure processing and thermal processes required much less energy than ultrasound for the same polyphenoloxidase inactivation in strawberry. While high-pressure processing retained better the antioxidant activity of the strawberry puree during storage, the ultrasound treatment was better in terms of color retention.

  14. Umai Dish Preparation Practices and Food Safety Behaviors in Bintulu Locals on Borneo Island, Malaysia
    Sukirman AN, Khalex HB, Mustafa S, Sarbini SR, Hassan S, S-Hussain SS, et al.
    J Food Prot, 2020 Oct 01;83(10):1764-1774.
    PMID: 32463874 DOI: 10.4315/JFP-19-543
    ABSTRACT: Umai is a popular, traditional, native dish of the Melanau ethnic group in Sarawak. It is prepared using thin slices of raw marine fish marinated with calamansi juice and seasoned with other ingredients. The local people believe that the acidity of the citrus juice, along with the use of salt and spice, can slightly cook the fish and remove the fishy smell. The aim of this study was to investigate (i) the different umai handling and preparation practices and (ii) the personal experience of umai consumption among respondents. A purposive sample of 100 umai makers, divided into two equal groups, professionals and nonprofessionals, participated in the study. We found that Spanish mackerel and hairfin anchovy were ranked first and second in the list of species chosen for making umai, with the former mostly preferred by the professional group, as opposed to the latter, which was preferred by the nonprofessional group. Black pomfret was ranked third, where it is equally preferred by both groups. About 20% of respondents would freeze the raw fish chunks prior to preparing umai, as opposed to 26% who would sun dry their fish. Other techniques, such as salting and marinating (using calamansi juice), were also used during the preparation of umai. Most of the respondents indicated that they would consider the umai ready to eat soon after marinating (with all ingredients) the raw fish. One-third of both respondent groups indicated that they would chill the umai dish at 4°C for 30 min before serving. The respondents could not provide any rationale behind these food preparation practices. Overall, this study provides evidence of the different preparation methods for umai. These practices can thus be considered important targets for public health education campaigns seeking to improve food safety surrounding this food group.

  15. Fulltext Structural equation modelling of food safety knowledge, attitude and practices among consumers in Malaysia
    Soon JM, Wahab IRA, Hamdan RH, Jamaludin MH
    PLoS One, 2020;15(7):e0235870.
    PMID: 32639978 DOI: 10.1371/journal.pone.0235870
    Factors contributing to foodborne illnesses in Malaysia were identified as insanitary food handling procedures and lack of hygiene in food preparation area. Food safety at home is a critical point as consumers represent the final step in food preparation and prevention of foodborne diseases. This study aims to investigate the food safety knowledge, attitude and self-reported practices among consumers in Malaysia. An online survey was conducted, and data were analysed using descriptive statistics and exploratory factor analysis. A model linking food safety knowledge and attitude and their direct effects on practices were confirmed using structural equation modelling (SEM). The proposed model fulfilled the goodness of fit indices and is deemed acceptable. Respondents demonstrate good level of food safety knowledge and positive attitudes and self-reported practices. Food safety knowledge has a negative and insignificant relationship with food safety practices (β1 = -0.284, p>0.05) while attitude significantly affects food safety practices (β1 = 0.534, p<0.05). The findings clearly indicate that food safety knowledge does not directly affect food safety practices This is also the first study to provide new empirical findings on thermometer usage among consumers in Malaysia. This study establishes an important point of reference where consumers use visual appearances to determine if food is thoroughly cooked and practice washing raw chicken prior to cooking. Food safety practices at home play a critical role in protecting consumers in reducing risks of foodborne illnesses.

  16. Fabrication of oil-in-water emulsions as shelf-stable liquid non-dairy creamers: effects of homogenization pressure, oil type, and emulsifier concentration
    Soo YN, Tan CP, Tan PY, Khalid N, Tan TB
    J Sci Food Agric, 2021 Apr;101(6):2455-2462.
    PMID: 33034060 DOI: 10.1002/jsfa.10871
    BACKGROUND: The popularity of coffee, the second most consumed beverage in the world, contributes to the high demand for liquid non-dairy creamer (LNDC). In this study, palm olein emulsions (as LNDCs) were investigated as alternatives to the more common soybean oil-based LNDCs. LNDCs were prepared via different homogenization pressures (100-300 bar) using different types of oil (palm olein and soybean oil) and concentrations of DATEM emulsifier (5-20 g kg-1 ).

    RESULTS: Increases in homogenization pressure and emulsifier concentration were observed to have significant (P  0.05) differences between the prepared and commercial LNDCs in terms of their color, appearance, and overall acceptability.

    CONCLUSION: Shelf-stable LNDCs with qualities comparable to commercial LNDC were successfully fabricated. Valuable insights into the effects of homogenization pressure, oil type, and emulsifier concentration, as well as functionality and consumer acceptance of the LNDCs when added into black coffee, were obtained. © 2020 Society of Chemical Industry.

    Siti Nurul Ain Saipullizan, Razalee Sedek, Sahilah Abd. Mutalib
    Sains Malaysiana, 2018;47:1527-1533.
    This study aimed to evaluate the level of knowledge, attitude and practice (KAP) amongst food handlers in food utensils
    hygiene and presence of bacterial contamination on food utensils. There were two approaches used in this study. In the
    first approach, 134 of food handlers from 75 food premises were interviewed via questionnaires to assess their knowledge,
    attitude and practice. In the second approach, the presence of Staphylococcus aureus, Escherichia coli and total coliform
    of 225 utensils (knives (75), chopping boards (75) and dish plates (75)) was examined. The result showed that the food
    handlers had sufficient level of knowledge (80.5%), attitude (87.4%) and practice (90.1%). Highest contamination was
    found on the chopping boards for the presence of S. aureus (82.8%), E. coli (9.7%) and total coliform (73.9%). Logistic
    regression analysis showed that knowledge contributes to the presence of E. coli on the dish plates; and total coliform
    on the knives. Thus, ongoing training that focused on food utensils hygiene must be emphasized to improve knowledge,
    attitude and practice amongst the food handlers.

  18. Fulltext New Insights on Degumming and Bleaching Process Parameters on The Formation of 3-Monochloropropane-1,2-Diol Esters and Glycidyl Esters in Refined, Bleached, Deodorized Palm Oil
    Sim BI, Muhamad H, Lai OM, Abas F, Yeoh CB, Nehdi IA, et al.
    J Oleo Sci, 2018 Apr 01;67(4):397-406.
    PMID: 29526878 DOI: 10.5650/jos.ess17210
    This paper examines the interactions of degumming and bleaching processes as well as their influences on the formation of 3-monochloropropane-1,2-diol esters (3-MCPDE) and glycidyl esters in refined, bleached and deodorized palm oil by using D-optimal design. Water degumming effectively reduced the 3-MCPDE content up to 50%. Acid activated bleaching earth had a greater effect on 3-MCPDE reduction compared to natural bleaching earth and acid activated bleaching earth with neutral pH, indicating that performance and adsorption capacities of bleaching earth are the predominant factors in the removal of esters, rather than its acidity profile. The combination of high dosage phosphoric acid during degumming with the use of acid activated bleaching earth eliminated almost all glycidyl esters during refining. Besides, the effects of crude palm oil quality was assessed and it was found that the quality of crude palm oil determines the level of formation of 3-MCPDE and glycidyl esters in palm oil during the high temperature deodorization step of physical refining process. Poor quality crude palm oil has strong impact towards 3-MCPDE and glycidyl esters formation due to the intrinsic components present within. The findings are useful to palm oil refining industry in choosing raw materials as an input during the refining process.

  19. Current intervention strategies for the microbial safety of sprouts
    Sikin AM, Zoellner C, Rizvi SS
    J Food Prot, 2013 Dec;76(12):2099-123.
    PMID: 24290689 DOI: 10.4315/0362-028X.JFP-12-437
    Sprouts have gained popularity worldwide due to their nutritional values and health benefits. The fact that their consumption has been associated with numerous outbreaks of foodborne illness threatens the $250 million market that this industry has established in the United States. Therefore, sprout manufacturers have utilized the U.S. Food and Drug Administration recommended application of 20,000 ppm of calcium hypochlorite solution to seeds before germination as a preventative method. Concentrations of up to 200 ppm of chlorine wash are also commonly used on sprouts. However, chlorine-based treatment achieves on average only 1- to 3-log reductions in bacteria and is associated with negative health and environmental issues. The search for alternative strategies has been widespread, involving chemical, biological, physical, and hurdle processes that can achieve up to 7-log reductions in bacteria in some cases. The compilation here of the current scientific data related to these techniques is used to compare their efficacy for ensuring the microbial safety of sprouts and their practicality for commercial producers. Of specific importance for alternative seed and sprout treatments is maintaining the industry-accepted germination rate of 95% and the sensorial attributes of the final product. This review provides an evaluation of suggested decontamination technologies for seeds and sprouts before, during, and after germination and concludes that thermal inactivation of seeds and irradiation of sprouts are the most practical stand-alone microbial safety interventions for sprout production.

    Shokryzadan P, Rajion MA, Meng GY, Boo LJ, Ebrahimi M, Royan M, et al.
    Crit Rev Food Sci Nutr, 2017 Sep 02;57(13):2737-2748.
    PMID: 26252346 DOI: 10.1080/10408398.2015.1060190
    Conjugated linoleic acid (CLA) is a mixture of isomers of linoleic acid (C18:2 n-6), which is mostly found in the ruminant meat and dairy products. The CLA is known to have many potential health benefits, and considered a potent powerful fatty acid, which is linked to animal and human health. The present work aims to discuss the source and production, mechanism of action, and effects of CLA on humans, poultry, and ruminants by reviewing the recent studies carried out on CLA. Despite most of the recent studies indicating beneficial effects of CLA on improving body weight control parameters, its effects on reducing risk factors of cardiovascular diseases (CVD), inflammation, blood glucose, and insulin are still controversial, and need to be further studied in different hosts.
