    As Malaysian economies grow, Malaysian per capita income is likely to increase. From economics point of view, it is expected that better-off consumers will move to better quality of food attributes such as freshness, food safety, quality and healthfulness in their food intake. This study aimed to investigate the demand for eggs attributes by Malaysian consumers. The study considers the conjoint analysis technique as a method for acquiring insights into preferences for eggs product. The technique was applied to establish the trade-offs that Malaysian consumers make between size, colour, size of packaging, functional attribute and price in the purchasing of eggs for 202 respondents. Least squares regression was utilized to estimate the relative importance of attributes for eggs. The results revealed that the ideal characteristic of egg was one with large size (grade A), omega eggs, brown, and ten per packs. We also found that consumers were also willing to pay more for their preferred attributes. The results found in the study provide valuable inputs to producers or marketers to improve their marketing efforts as well as market positioning, in line with the demanded eggs attributes.

    Consumption of iced beverages is common in Malaysia although specific research focusing on its safety parameters such as presence of faecal coliforms and heavy metal elements remains scarce. A study conducted in Kelantan indicated that faecal coliforms were detected in the majority of the ice cube samples analyzed, largely attributable to improper handling. Hence, it was found pertinent to conduct similar study in other parts of the country such as Johor Bahru if the similar pattern prevailed. Therefore, this present cross sectional study which randomly sampled ice cubes from 30 permanent food outlets in Taman Universiti, Johor Bahru for detecting contamination by faecal coliforms and selected heavy metal elements (lead, copper, manganese and zinc) acquires significance. Faecal coliforms were detected in 11 (36.67%) of the samples, ranging between 1 CFU/100 mL to > 50 CFU/100 mL; two of the samples were grossly contaminated (>50 CFU/100 mL). Interestingly, while positive detection of lead was observed in 29 of the 30 ice cube samples (mean: 0.511±0.105 ppm; range: 0.489-0.674 ppm), copper, manganese and zinc were not detected. In addition, analysis on commercially bottled mineral water as well as in tap water samples did not detect such contaminations. Therefore, it appears that (1) contamination of faecal coliforms in ice cubes in food outlets in Malaysia may not be sporadic in pattern but rather prevalent and (2) the source of water used for manufacturing the ice cubes that contained significant amount of lead would suggest that (3) it was neither originated from the treated tap water supply nor bottled mineral water or (4) perhaps contaminated during manufacturing process. Further studies exploring the source of water used for manufacturing these ice cubes as well as the handling process among food operators deserve consideration.

    Food contamination is a crucial health problem as it could result in food-borne illness. This research aimed to evaluate the microbiological quality of ready-to-eat (RTE) fried rice dishes sold at different type of food premises in Kuantan city, Pahang. Total Plate Count (TPC), Staphylococcus aureus, Bacillus cereus and Aeromonas spp. bacteria were used as microbiological contamination indicators. About 52 samples were collected stratified randomly from four types of food premises (restaurant, cafeteria, food stall and night market) where about 13 samples were respectively collected from each type of the food premises. The results showed that TPC had medium mean count (6.30x105±1.47x105 cfu/g), S. aureus and B. cereus had high mean counts (7.70x104±2.22x105 cfu/g and 3.85x105±1.67x106 cfu/g respectively), while Aeromonas spp. had medium mean count (7.13x104±2.42x105 cfu/g). The mean counts of TPC in the samples collected from cafeteria were highest compare to other food premises.

    An international survey among consumers in developing countries from Asia and Africa on food safety knowledge, attitudes and practices (KAP) was carried out using structured questionnaires. Data were collected from 453 consumers comprising 265 from Africa and 188 from Asia. Significant difference (p food safety knowledge attitude and practice between consumers from Africa and Asia was observed. In Africa, consumers in Cameroon had the least food safety knowledge (73.15 ± 16.43) compared to Ghana (78.19 ± 15.84) and Nigeria (88.16 ± 8.88). Similarly, consumers in Iran had the least food safety knowledge (73.33 ± 19.84) in Asia compared to Malaysia (88.36 ± 11.64) and Pakistan (89.42 ± 9.89). Among the respondents, 89% were aware of food poisoning while 304 (67.1%) consume food kept for long at room temperature. There was significant difference (p food safety knowledge, attitudes and practices of consumers between Africa and Asia. Overall, respondents from Asia have better food safety knowledge than respondents from Africa.

    A developed colorimetric pH sensor film based on edible materials for real-time monitoring of food freshness is described. The mixed natural dyes from edible plants Clitoria sp and Brassica sp were extracted and incorporated into ι-carrageenan film as a colorimetric pH sensor film for monitoring food spoilage and its freshness. The color changes of the developed colorimetric sensor film were measured with chromametry and UV-vis spectroscopy, respectively. Experimental results show that colorimetric pH sensor film demonstrated statistically significant differences (p < 0.05) between CIE-L*a*b* coordinates color system indicated that the developed colorimetric sensor film was able to give a gradual change in color over a wide pH range. The color of the colorimetric sensor film also changes discretely and linearly with factors that contribute to food spoilage using shrimp and durian samples. Moreover, the developed colorimetric pH sensor film has the potential to be used as a safe, non-destructive testing and also a flexibly visual method for direct assessment of food freshness indicator during storage.

    BACKGROUND: Food serves as a vehicle for many pathogenic and toxigenic agents that cause food-borne diseases. Knowledge, attitude, and practices are key factors in reducing the incidence of food-borne diseases in food service areas. The main objective of this study was to evaluate knowledge, attitude, and practices related to food poisoning among parents of children in Nablus, Palestine.

    METHODS: A cross-sectional study was conducted in primary healthcare centers in Nablus district from May to July 2015. Data were collected using structured questionnaire interviews with parents to collect information on food safety knowledge, attitudes, and practices, alongside sociodemographic characteristics.

    RESULTS: Four-hundred and twelve parents were interviewed, 92.7% were mothers. The median knowledge score was 12.0 with an interquartile range (IQR) of 11.0-14.0. The median attitude score was 11.0 with IQR of 10.0-13.0, while the median practice score was 18.0 with IQR of 16.0-19.0. Significant modest positive correlations were found between respondents' knowledge and attitude scores regarding food poisoning (r = 0.24, p food poisoning (r = 0.23, p food poisoning (r = 0.30, p food poisoning (p food poisoning prevention are associated with each other and are affected by a complex interplay between socio-economic variables. The study highlights the need for health education programmes and general awareness campaigns that intend not only to enhance knowledge but also promote parents to practice food safety measures strictly and further strengthen their awareness level.

    Consumers' demand is increasing for safe foods without impairing the phytochemical and sensory quality. In turn, it has increased research interest in the exploration of innovative food processing technologies. Cold plasma technology is getting popularity now days owing to its high efficacy in decontamination of microbes in fruit and fruit-based products. As a on-thermal approach, plasma processing maintains the quality of fruits and minimizes the thermal effects on nutritional properties. Cold plasma is also exploited for inactivating enzymes and degrading pesticides as both are directly related with quality loss and presently are most important concerns in fresh produce industry. The present review covers the influence of cold plasma technology on reducing microbial risks and enhancing the quality attributes in fruits.

    With the growing interest in food safety and in environmental protection, it is more attractive to develop novel biodegradable packaging films. In this regard, one new blending film was prepared with curdlan (CD)/polyvinyl alcohol (PVA)/thyme essential oil. Our results demonstrated that the mechanical properties of the blending film were the best when the ratio of the CD and PVA was 4:1. Further, the barrier properties of the film were optimized by incorporating with thyme essential oil. It was proved that not only water vapor permeability was lower, but also the elongation at break was improved, when 2% (w/w) thyme essential oil used. The potential interactions of the film matrix were analyzed by FTIR, XRD and Cryo-scanning electron microscopy. Importantly, both the antioxidant activity and antibacterial activity were improved. Finally, the blending film was employed for the preservation of chilled meat, while the shelf life was extended up to 10 days.

    Animal species identification is one of the important fields in forensic science. Unlike human forensics which makes use of DNA fingerprinting techniques to identify individuals of the same species - humans, animal forensic species identification is much more complicated as it involves the ability to identify and distinguish between hundreds to thousands of species when the material evidence is only a trace of animal tissue without the presence of any visual physical morphology. It is even more difficult when the specimen is an unknown and no reference material is available. Animal species identification is not only important for the prevention of wildlife crimes for the purpose of wildlife protection and conservation but it is also becoming more and more significant in food safety issues especially for the meat industry. Owing to the demand and the necessity of providing such services for regulation and enforcement in the context of environmental protection, food safety and biosafety, the Department of Chemistry (DOC)
    Malaysia has initiated the use of DNA techniques employing the most widely used genetic markers as part of its scientific solution for animal species identification.

    Introduction: Food poisoning may occur as single sporadic cases or massive outbreak in any institution, including boarding schools. Early this year, Cheras District Health Office had implemented set of interactive games on food safety programme at two boarding schools in Cheras which had repeated incidences of food poisoning outbreak. This study aims to evaluate the effectiveness of interactive games on knowledge of food safety among school children in Cheras. Methods: This study is a retrospective study based on secondary data. Two boarding school with total of 135 students were. The students were divided into 4 groups and participates in all 4 modules of interactive games. There were 10 items pre and post questionnaire on food safety knowledge collected during the program with score ranged zero to ten. The data were analysed descriptively and analytically with paired t test. Results: The response rate of this study was 100 %. Majority of the respondents were Malays (68.1%) and male (66.7%). The mean score at pre and post were 6.78 and 7.72 respectively. Paired t test showed that there was a significant increase of 0.94 mean score of knowledge after the programme (p-value < 0.05, CI 95%= -1.212, -0.664). Conclusion: The knowledge scores on food safety of the students increased significantly after the interactive game. However, without control group, the improvement cannot be said solely due to the program itself.

    The term ‘sustainable’ has become a buzz word in today’s business world. Consumption of green food is just one facet or ‘trip’ to the whole journey of sustainable development. This paper explores and synthesizes the findings of research on green food consumption in Malaysia. The already conducted studies in Malaysia have revealed various demographic and psychographic factors contributing to consumers’ intension to buy green food. This study revealed that majority of Malaysians consider food safety and health issue to be their prime reason for buying green food. To ensure the long term sustainability, the green food as well as the broad food industry in Malaysia must evidently understand the consumers’ buying motives of green food. Although mentionable limitation of the paper is the reliance on only published literature, this can be used as input for further large scale empirical research. The paper concludes with implications and suggestions for further research.

    Background and Objective : Johor was affected by the worst flood in 100 years in December 2006 and again in January 2007. The concern that improper sanitary facilities and contaminated water supply at relief centres would result in contaminated food made monitoring of food hygiene vital. The objective of this paper is to describe food hygiene surveillance activities carried out in flood relief centres and flood affected areas and the challenges faced in carrying out these activities.
    Methodology : The food hygiene surveillance activities were carried out by the Assistant Environmental Health Officers (AEHO) in the districts. Among the surveillance activities carried out are inspection of food preparation areas in relief centres, inspection of food premises in flood affected areas and food sampling. Premise inspections were carried out using a specific inspection format. Food samples taken were sent to Public Health Laboratory, Johor Bahru for microbiological analysis. Anti typhoid vaccination for food handlers were also carried out. Apart from that, observations made by the health teams were alsotaken into account.
    Results : A total of 3,159 food preparation areas in relief centres were inspected. During the same period, a total of 2,317 food premises in flood affected areas were inspected as soon these premises started operating after the floods. Inspections showed that 69 food preparation areas in relief centres and 181 food premises in flood affected areas had unsatisfactory hygiene. A total of 1,566 holding samples were taken and 425 samples were sent to the laboratory for analysis. Forty-six of the samples analysed were found to be positive for pathogenic bacteria such as e. coli, staphylococcus aureus and salmonella.
    Conclusion : The health personnel from the Johor Health Department in various districts carried out an excellent job in ensuring food safety during the floods. There were no outbreaks of food poisoning. However analysis of food samples taken during the floods did show the presence of pathogenic organisms but probably their numbers were not high enough to cause any food poisoning. The promotion and enforcement of food hygiene requirements should be carried out continuously to ensure that every individual understands the need for hygiene and food safety during disaster situation such as flood.

    Scombroid fish poisoning is usually associated with consumption of fish containing high levels of histamine. However, reports indicate that some cases have responded to antihistamine therapy while ingested histamine levels in these cases were low. Potentiation of histamine toxicity by some biogenic amines, and release of endogenous histamine by other compounds such as cis-urocanic acid (UCA) are some hypotheses that have been put forth to explain this anomaly. Very little is known about the effects of storage conditions on the production of both UCA isomers and biogenic amines in tuna. Thus, the production of trans- and cis-UCA, histamine, putrescine, and cadaverine in tuna during 15 d of storage at 0, 3, and 10 °C and 2 d storage at ambient temperature were monitored. The initial trans- and cis-UCA contents in fresh tuna were 2.90 and 1.47 mg/kg, respectively, whereas the levels of putrescine and cadaverine were less than 2 mg/kg, and histamine was not detected. The highest levels of trans- and cis-UCA were obtained during 15 d storage at 3 °C (23.74 and 21.79 mg/kg, respectively) while the highest concentrations of histamine (2796 mg/kg), putrescine (220.32 mg/kg) and cadaverine (1045.20 mg/kg) were obtained during storage at room temperature, 10 and 10 °C, respectively. Histamine content increased considerably during storage at 10 °C whereas trans- and cis-UCA contents changed slightly. The initial trans-UCA content decreased during storage at ambient temperature. Thus, unlike histamine, concentrations of trans- and cis-UCA did not result in elevated levels during storage of tuna.

    Next Generation Sequencing (NGS) combined with powerful bioinformatic approaches are revolutionising food microbiology. Whole genome sequencing (WGS) of single isolates allows the most detailed comparison possible hitherto of individual strains. The two principle approaches for strain discrimination, single nucleotide polymorphism (SNP) analysis and genomic multi-locus sequence typing (MLST) are showing concordant results for phylogenetic clustering and are complementary to each other. Metabarcoding and metagenomics, applied to total DNA isolated from either food materials or the production environment, allows the identification of complete microbial populations. Metagenomics identifies the entire gene content and when coupled to transcriptomics or proteomics, allows the identification of functional capacity and biochemical activity of microbial populations. The focus of this review is on the recent use and future potential of NGS in food microbiology and on current challenges. Guidance is provided for new users, such as public health departments and the food industry, on the implementation of NGS and how to critically interpret results and place them in a broader context. The review aims to promote the broader application of NGS technologies within the food industry as well as highlight knowledge gaps and novel applications of NGS with the aim of driving future research and increasing food safety outputs from its wider use.

    The agricultural industry has made a tremendous contribution to the foundations of civilization. Basic essentials such as food, beverages, clothes and domestic materials are enriched by the agricultural industry. However, the traditional method in agriculture cultivation is labor-intensive and inadequate to meet the accelerating nature of human demands. This scenario raises the need to explore state-of-the-art crop cultivation and harvesting technologies. In this regard, optics and photonics technologies have proven to be effective solutions. This paper aims to present a comprehensive review of three photonic techniques, namely imaging, spectroscopy and spectral imaging, in a comparative manner for agriculture applications. Essentially, the spectral imaging technique is a robust solution which combines the benefits of both imaging and spectroscopy but faces the risk of underutilization. This review also comprehends the practicality of all three techniques by presenting existing examples in agricultural applications. Furthermore, the potential of these techniques is reviewed and critiqued by looking into agricultural activities involving palm oil, rubber, and agro-food crops. All the possible issues and challenges in implementing the photonic techniques in agriculture are given prominence with a few selective recommendations. The highlighted insights in this review will hopefully lead to an increased effort in the development of photonics applications for the future agricultural industry.

    The contamination of food and feed by Aspergillus has become a global issue with a significant worldwide economic impact. The growth of Aspergillus is unfavourable to the development of food and feed industries, where the problems happen mostly due to the presence of mycotoxins, which is a toxic metabolite secreted by most Aspergillus groups. Moreover, fungi can produce spores that cause diseases, such as allergies and asthma, especially to human beings. High temperature, high moisture, retarded crops, and poor food storage conditions encourage the growth of mold, as well as the development of mycotoxins. A variety of chemical, biological, and physical strategies have been developed to control the production of mycotoxins. A biological approach, using a mixed culture comprised of Saccharomyces cerevisiae and Lactobacillus rhamnosus resulted in the inhibition of the growth of fungi when inoculated into fermented food. The results reveal that the mixed culture has a higher potential (37.08%) to inhibit the growth of Aspergillus flavus (producer of Aflatoxin) compared to either single culture, L. rhamnosus NRRL B-442 and S. cerevisiae, which inhibit the growth by 63.07% and 64.24%, respectively.

    Technological advances, coupled with increasing demands by consumers, have led to a drastic increase in plastic production. After serving their purposes, these plastics reach our water bodies as their destination and become ingested by aquatic organisms. This ubiquitous phenomenon has exposed humans to microplastics mostly through the consumption of sea food. This has led the World Health Organization (WHO) to make an urgent call for the assessment of environmental pollution due to microplastics and its effect on human health. This review summarizes studies between 1999 and 2020 in relation to microplastics in aquatic ecosystems and human food products, their potential toxic effects as elicited in animal studies, and policies on their use and disposal. There is a paucity of information on the toxicity mechanisms of microplastics in animal studies, and despite their documented presence in food products, no policy has been in place so far, to monitor and regulates microplastics in commercial foods meant for human consumption. Although there are policies and regulations with respect to plastics, these are only in a few countries and in most instances are not fully implemented due to socioeconomic reasons, so they do not address the problem across the entire life cycle of plastics from production to disposal. More animal research to elucidate pathways and early biomarkers of microplastic toxicity that can easily be detected in humans is needed. This is to create awareness and influence policies that will address this neglected threat to food safety and security.

    A total of 40 marine mussel Perna viridis populations collected (2002-2009) from 20 geographical sites located in two busy shipping lanes namely the Straits of Malacca (10 sites; 16 populations) and the Straits of Johore (8 sites; 21 populations) and three populations (2 sites) on the east coast of Peninsular Malaysia, was determined for Cd, Cu, Fe, Ni, Pb and Zn concentrations. In comparison with the maximum permissible limits (MPLs) set by existing food safety guidelines, all metal concentrations found in all the mussel populations were lower than the prescribed MPLs. In terms of the provisional tolerable weekly intake prescribed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and oral reference doses (ORDs) by the USEPA, all the studied metals (except for Pb) were unlikely to become the limiting factors or unlikely to pose a risk for the consumption of the mussel populations. The estimated daily intake (EDI) for average level mussel (ALM) and high level mussel (HLM) consumers of mussels was found to be lower than the ORD guidelines for Cd, Cu, Fe, Ni and Zn. Furthermore, the target hazard quotient (THQ) was found to be less than 1 for ALM consumers but higher than 1 for HLM consumers in some sites. Therefore, there were no potential human health risks to the ALM consumers of the mussels. However, for Pb THQ values, the Pb levels in some mussel populations could create a health risk problem. Present results indicate that the consumption amounts of mussels should be limited for minimizing potential health risks of heavy metals to the HLM consumers.
