    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.

    Microplastic pollution is a global issue that has a detrimental impact on food safety. In marine environments, microplastics are a threat to marine organisms, as they are often the same size range as prey and are mistaken as food. Consumption of microplastics has led to the damage of digestive organs and a reduction in growth and reproductive output. In this study, microplastic pollution was assessed across three commercially available shrimp species that were obtained from the supermarkets of Singapore. A total of 93 individuals were studied from the Pacific white leg shrimp, Litopenaeus vannamei, the Argentine red shrimp Pleoticus muelleri and the Indian white shrimp Fenneropenaeus indicus. Microplastic fibers, fragments, film and spheres were identified from the digestive tract of these organisms. Microplastic abundance ranged from 13.4 to 7050 items. F. indicus exhibited the highest number of microplastics. Microplastic film was the most abundant in L. vannamei individuals (93-97%) and spheres were the most abundant in P. muelleri (70%) and F. indicus (61%) individuals. This study demonstrates that microplastic contamination is evident in commonly consumed shrimp and highlights the role of shrimp in the trophic transfer and accumulation of microplastics in seafood. The consumption of microplastic-containing seafood is a route of exposure to humans and has implications on human health and food security. Capsule: Microplastics were examined in three shrimp species from the supermarkets of Singapore. Microplastics ranged from 13.4 to 7050 items of shrimp.

    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.

    Biological amines are nitrogenous compounds that occur naturally in wide variety of food. Histamine, putrescine, cadavarine, tyramine, spermine, spermidine, tryptamine and β-phenylethylamine are the biogenic amines that are normally present in foods. Although the biogenic amines play some important physiological functions but high level of amines can cause toxicological effects. High amount of amines can be produced by bacteria during amino acids decarboxylation and have been identified as one of the important agent causing seafood intoxication. Temperature is the major factor for controlling the biogenic amines formation in food. The effects of other alternatives are also discussed including salting, packaging, irradiation, high pressure processing and the use of starter culture. A variety of techniques can be combined together to control the microbial growth and enzyme activity during processing and storage for better shelf life extension and food safety.

    Migration of melamine has been determined for 41 types of retail melamine-ware products in Malaysia. This study was initiated by the Ministry of Health, Malaysia, in the midst of public anxiety on the possibility of melamine leaching into foods that come into contact with the melamine-ware. Thus, the objective of this study was to investigate the level of melamine migration in melamine utensils available on the market. Samples of melamine tableware, including cups and plates, forks and spoons, tumblers, bowls, etc., were collected from various retail outlets. Following the test guidelines for melamine migration set by the European Committee for Standardisation (CEN 2004) with some modifications, the samples were exposed to two types of food simulants (3% acetic acid and distilled water) at three test conditions (25°C (room temperature), 70 and 100°C) for 30 min. Melamine analysis was carried out using LC-MS/MS with a HILIC column and mobile phase consisting of ammonium acetate/formic acid (0.05%) in water and ammonium acetate/formic acid (0.05%) in acetonitrile (95 : 5, v/v). The limit of quantification (LOQ) was 5 ng/ml. Melamine migration was detected from all samples. For the articles tested with distilled water, melamine migration were [median (interquartile range)] 22.2 (32.6), 49.3 (50.9), 84.9 (89.9) ng/ml at room temperature (25°C), 70 and 100°C, respectively. In 3% acetic acid, melamine migration was 31.5 (35.7), 81.5 (76.2), 122.0 (126.7) ng/ml at room temperature (25°C), 70 and 100°C, respectively. This study suggests that excessive heat and acidity may directly affect melamine migration from melamine-ware products. However the results showed that melamine migration in the tested items were well below the specific migration limit (SML) of 30 mg/kg (30,000 ng/ml) set out in European Commission Directive 2002/72/EC.

    BACKGROUND: Annually, 600 million individuals are affected by food-borne diseases (FBD), alongside 425,000 fatalities. Improving the general public knowledge of, attitudes towards, and practices in, (KAP) food safety is necessary for minimizing FBD transmission. In Malaysia, migrant workers account for 11.1% of the workforce, with a high proportion involved in food and beverage services. Therefore, this study aimed (i) to evaluate the current food safety KAP, and (ii) to identify the strategies to promote food safety awareness, among migrant workers across occupational sectors in Klang Valley.

    METHOD: A survey was conducted with 403 migrant workers through phone interviews and online self-administered questionnaires. Piecewise structural equation modelling and multinomial regression were applied to identify predictor variables for food safety KAP and to explore differences across nationalities.

    RESULTS: The respondents were Nepalese, Filipino and Indonesian. The majority were male, working in the services industry, had completed high school, aged between 30 and 39 years and had worked in Malaysia for less than ten years. Knowledge was significantly correlated with attitudes and practices. Female respondents had lower knowledge and attitude scores while younger respondents had lower knowledge scores. Indonesian and Filipino respondents had lower knowledge and attitudes scores than Nepalese respondents. Understanding food safety information from social media was positively correlated with the respondents' food safety knowledge and practices.

    CONCLUSION: These findings highlighted: (i) the need to target female, younger, Indonesian and Filipino migrant workers, and (ii) the potential of social media to improve public awareness of food safety and hygienic practices.

    Listeria spp. and Salmonella spp. are capable of causing food-borne outbreaks and diseases in humans. This study aimed to quantify and detect the occurrence of Listeria monocytogenes and Salmonella Typhimurium in fruit juices by utilizing Most Probable Number (MPN) in combination with Polymerase Chain Reaction (PCR). In this study, a total of 50 fruit juice samples, consisting of orange, papaya, watermelon, honeydew and apple were collected from Kota Samarahan and Kuching. Specific Polymerase Chain Reaction (PCR) assay targeting the virulence gene, hlyA gene in L. monocytogenes and fliC gene in S. Typhimurium was performed, with the expected size of 730 bp and 559 bp, respectively. MPN analysis showed that the estimated microbial loads of Listeria spp. and Salmonella spp. in all samples were more than 1100 MPN/g. However, based on the PCR analysis, none of the samples (0%) were positive for L. monocytogenes or S. Typhimurium. This study presented as a preliminary food safety screening for the occurrence of Listeria spp. and Salmonella spp. from retailed fruit juices. Hygienic practices and food safety measures should be adhered by all food vendors and restaurants in order to avoid foodborne disease outbreaks in the future.

      Disease outbreaks due to the consumption of contaminated food and feedstuff are a recurring problem worldwide. The major factor contributing to contamination are microorganisms, especially fungi, which produce low-molecular-weight compounds as secondary metabolites, with confirmed toxic properties referred to as mycotoxins. Several mycotoxins reported to date are cosmopolitan in distribution and incur severe health-associated risks (including cancer and neurological disorders). Hence, creating awareness among consumers, as well as developing new methods for detection and inactivation is of great importance for food safety. In this review, the focus is on the occurrence of various types of mycotoxins in food and feed associated with risks to humans and livestock, as well as legislation put forth by various authorities, and on presently practiced detoxification methods. Brief descriptions on recent developments in mycotoxin detection methodology are also inlcuded. This review is meant to be informative not only for health-conscious consumers but also for experts in the field to pave the way for future research to fill the existing gaps in our knowledge with regard to mycotoxins and food safety.

    Consumption of repeatedly heated oil can be detrimental to health. The objective of this study was to determine the level of knowledge, attitude and practice of night market food outlet operators in Kuala Lumpur regarding the usage of repeatedly heated cooking oil. The quality of cooking oil was also investigated. A cross-sectional study involving pretested questionnaire was undertaken in April 2009. The questionnaire was designed as a tool to collect data from the respondents (n=100) by face-to-face interview. The results showed that majority of respondents had only moderate (53.0%) or low (18.0%) level of knowledge regarding this issue. Most respondents (67.0%) agreed that it is not a good practice. The majority (69.0%) agreed that the usage of repeatedly heated cooking oil is detrimental to health. Despite that, most respondents (63.0%) admitted that they had used cooking oil repeatedly. Most (62.0%) of the cooking oil samples taken from the night market food outlets were considered fit for human consumption. In conclusion, the level of knowledge of night market food outlet operators in Kuala Lumpur regarding this issue needs to be improved in order to ensure the safety of fried food purchased from such establishments.

    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.

    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.

    The growth of the Malaysian’s per capita income has generally empowered consumers to have more choices for food, more purchasing power, health consciousness and demand for more nutritional values of their food intake. Motivated by the changes in Malaysian consumer’s food choice, a conjoint analysis was performed to investigate Malaysian consumers’ demand for rice attributes and how much consumers are willing to pay for the demanded attribute. A conjoint analysis is a method used in identifying and understanding the combined effects of product attributes on preferences for a product or service. In conjoint analysis, utility is the conceptual basis for assessing the value of a product or service, where individuals make decisions between bundles of products based on their budget constraints. The findings suggested that the most important attribute for rice was food safety, followed by taste and size of grain. Consumers were also willing to pay premium prices for the demanded attributes. The findings would have positive implications for the agrifood industry if it responds effectively to translate into business opportunities to these changes.

     Fungi are distributed worldwide and can be found in various foods and feedstuffs from almost every part of the world. Mycotoxins are secondary metabolites produced by some fungal species and may impose food safety risks to human health. Among all mycotoxins, aflatoxins (AFs), ochratoxin A (OTA), trichothecenes, deoxynivalenol (DON and T-2 toxin), zearalenone (ZEN), and fumonisins (FMN) have received much attention due to high frequency and severe health effects in humans and animals. Malaysia has heavy rainfall throughout the year, high temperatures (28 to 31 °C), and high relative humidity (70% to 80% during wet seasons). Stored crops under such conditions can easily be contaminated by mycotoxin-producing fungi. The most important mycotoxins in Malaysian foods are AFs, OTA, DON, ZEN, and FMN that can be found in peanuts, cereal grains, cocoa beans, and spices. AFs have been reported to occur in several cereal grains, feeds, nuts, and nut products consumed in Malaysia. Spices, oilseeds, milk, eggs, and herbal medicines have been reported to be contaminated with AFs (lower than the Malaysian acceptable level of 35 ng/g for total AFs). OTA, a possible human carcinogen, was reported in cereal grains, nuts, and spices in Malaysian market. ZEN was detected in Malaysian rice, oat, barley, maize meal, and wheat at different levels. DON contamination, although at low levels, was reported in rice, maize, barley, oat, wheat, and wheat-based products in Malaysia. FMN was reported in feed and some cereal grains consumed in Malaysia. Since some food commodities are more susceptible than others to fungal growth and mycotoxin contamination, more stringent prevention and control methods are required.

    INTRODUCTION: fish can be an affordable and accessible animal-source food in many Low- and Middle-Income Countries (LMIC).

    BACKGROUND: Traditional fish processing methods pose a risk of exposing fish to various contaminants that may reduce their nutritional benefit. In addition, a lack of literacy may increase women fish processors' vulnerability to malnutrition and foodborne diseases.

    OBJECTIVE: The overall aim of the project was to educate women and youth fish processors in Delta State, Nigeria about the benefit of fish in the human diet and to develop low literacy tools to help them better market their products. The objective of this study was to describe the development and validation of a low-literacy flipbook designed to teach women fish processors about nutrition and food safety.

    METHOD: developing and validating instructional material requires understanding the population, high-quality and relevant graphics, and the involvement of relevant experts to conduct the content validation using the Content Validity Index (CVI) and the index value translated with the Modified Kappa Index (k).

    RESULT: The Item-level Content Validity Index (I-CVI) value of all domains evaluated at the initial stage was 0.83 and the Scale-level Content Validity Index (S-CVI) was 0.90. At the final stage, the material was validated with CVI 0.983 by four experts and satisfied the expected minimum CVI value for this study (CVI ≥ 0.83, p-value = 0.05). The overall evaluation of the newly developed and validated flipbook was "excellent".

    CONCLUSIONS: the developed material was found to be appropriate for training fish processors in Nigeria in nutrition and food safety and could be modified for a population of fish processors in other LMICs.

    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.

    Foodborne diseases are common in the developing countries due to the predominant poor food handling and sanitation practices, particularly as a result of inadequate food safety laws, weak regulatory structures, and inadequate funding as well as a lack of appropriate education for food-handlers. The most frequently involved foods in disease outbreaks are of animal origin. However, in spite of the adequate legislation and laws governing the abattoir operation in Malaysia, compliance with food safety requirements during meat processing and waste disposal is inadequate. Therefore, the present study was designed to assess the food safety knowledge, attitude, and practice toward compliance with abattoir laws among the workers in Terengganu, Malaysia.

    Salmonella is an important foodborne pathogen, whose ability to resist stress and survive can vary among strains. This variability is normally not taken into account when predictions are made about survival in foods with negative consequences. Therefore, we examined the contribution of variable phenotypic properties to survival under stress in 10 Salmonella serovars. One strain (Typhimurium 10) was intentionally RpoS-negative; however, another strain (Heidelberg) showed an rpoS mutation, rendering it inactive. We assessed an array of characteristics (motility, biofilm formation, bile resistance, acid resistance, and colony morphology) that show major variability among strains associated with a 10- to 19-fold difference between the highest and the lowest strain for most characteristics. The RpoS status of isolates did not affect variability in the characteristics, with the exception of resistance to NaCl, acetic acid, lactic acid, and the combination of acetic acid and salt, where the variability between the highest and the lowest strain was reduced to 3.1-fold, 1.7-fold, 2-fold, and 1.7-fold, respectively, showing that variability was significant among RpoS-positive strains. Furthermore, we also found a good correlation between acid resistance and lysine decarboxylase activity, showing its importance for acid resistance, and demonstrated a possible role of RpoS in the lysine decarboxylase activity in Salmonella.

    Although the Halal concept has not been a major element among non-Muslim consumers living in an Islamic country, whether the non-Muslim consumers are aware of the underlying advantages that come with Halal food products or their viewpoints arising from their religious belief, are some intriguing questions that need to be answered. Thus the objective of the study explore the underlying determinants that are likely to influence non-Muslim consumers’ perceptions and attitudes towards Halal concept and Halal food products in Malaysia in lieu of new paradigm in emerging global issues on sustainability, environmental, food safety and animal welfare. A survey was conducted in the Klang Valley where 400 non-Muslim respondents were interviewed via structured questionnaires to gather information on their awareness and attitude towards Halal food products in the Malaysian food market. Descriptive statistic was used to identify the socio-economic/ demographic characteristics and attitudes of the respondents toward the Halal food principles. The logit model
    was used to determine the extent to which selected socio-economic/demographic characteristics influenced
    the respondents’ attitude and understanding on Halal principles and Halal food products. The results of this
    study suggest that non-Muslim consumers are aware of the existence of Halal food, Halal principles and the
    advantages of Halal way in slaughtering the animals. This can be shown by their significant awareness that
    Halal is not only the way Muslim slaughter their animals but also relates to environmental, sustainability,
    animal welfare and food safety. In general, various socio-economic/demographic factors such as education
    level, older generation, those who are more religious and the urban dweller seem to more likely to be aware of the advantages of Halal principles.
