Objective: The occurrence of food contaminants such as aflatoxin in the foodstuffs has been reported widely. Unfortunately, only a few know about the impact of aflatoxin to human health and this phenomenon let us to question the extent of public’s knowledge on fungal and aflatoxin contamination in the diets. Thus, this study aimed to investigate determinants of adults’ knowledge on fungal and aflatoxin contamination in the diets based on two factors namely socio-demographic and socio-economic factors. Method: A questionnaire was self-administered to 160 respondents from a faculty in Universiti Putra Malaysia. Results: Most of respondents had low level of knowledge in regard to fungal and aflatoxin contamination. Besides, the total score of knowledge on fungal and aflatoxin contamination was significantly and positively correlated (r=0.340, P<0.0001). The multivariate analysis indicated that personal income (below US $487) was the only predictor of respondent’s knowledge (β=-0.288, P<0.001) [Odds ratio (OR)=4.996]. Nonetheless, being male and single, divorced or widowed had significant OR of 2.040 and 0.313 respectively as predictors of low level of knowledge. Conclusions: Income inequalities may have impact to the respondents in acquiring knowledge on fungal and aflatoxin contamination in the diets. Additionally, an extensive survey on aflatoxin should be warranted in order to assess the public awareness and knowledge about this food contaminant.

Aflatoxins are ubiquitous and occur in food. Exposure to aflatoxins seriously impact the health of human and animal.
It is concerning especially when aflatoxins are odourless, colourless, and tasteless that hardly be detected through
naked eyes. Ingestion of aflatoxin-contaminated food contributes the major route of exposure. The present review is
an update on the aflatoxin occurrence in food, aflatoxin regulations in food, and recent risk assessment of aflatoxin exposure in Malaysia. Peanuts and chili were more prone to aflatoxin contamination in Malaysia. The extreme
weather experienced in Malaysia and global climatic change may worsen the aflatoxin contamination in food. The
regulatory standards for aflatoxins imposed by Malaysia are less stringent than developed countries. The dietary exposure of aflatoxins among Malaysian was relatively high as compared with other Asia countries, ranging from 0.002
to 34.00 ng/kg body weight/day. Nonetheless, Malaysian population had low risk of aflatoxin-related liver cancer,
with an estimated liver cancer risk of <1 cancer case/100,000 population/year.

Introduction: Chronic exposure to aflatoxin can lead to complications such as liver failure and cancer. There are many factors that affect aflatoxin occurrence. This study aimed to assess the association between sociodemographic factors and the knowledge, attitude and practice towards aflatoxin with urinary aflatoxin M1 occurrence among residents in Hulu Langat district, Malaysia. Methods: This was a cross-sectional study conducted among healthy Malaysian adults aged 18 to 60 years residing in Hulu Langat district, Malaysia. Socio-demographic background and the knowledge, attitude and practice of respondents towards aflatoxin were assessed through questionnaires. Non-fasting urine sample (15 ml) was collected in the morning and urinary aflatoxin M1 level was quantified. Results: Of the 444 healthy Malaysian adults, 199 urine samples were detected with aflatoxin M1. From 37 positive samples with aflatoxin M1 level above detection limit (0.64 ng/ml), mean value was 1.23±0.91 ng/ml (range = 0.65-5.34 ng/ml). Urinary aflatoxin M1 occurrence was significantly different across ethnicity, age group, monthly household income, attitude and practice towards aflatoxin. Binomial logistic regression confirmed ethnicity and monthly household income as factors contributing to urinary aflatoxin M1 occurrence. Chinese were 3.20 times more likely to have aflatoxin exposure than non-Chinese. Detected urinary aflatoxin M1 was more common among household with a monthly income above RM1,500. Conclusion: The results provided an insight to explain the variation in aflatoxin occurrence among the population.
4.Effects of Lacticaseibacillus paracasei Shirota Supplementation on Growth Performance, Intestinal Health, and Fecal AFB1 Metabolite in AFB1-Exposed Rats (Kesan Pemberian Lacticaseibacillus paracasei Shirota terhadap Prestasi Pertumbuhan, Kesihatan Usus dan Metabolit AFB1 di dalam Najis Tikus Terdedah AFB1)

Aflatoxin B1 (AFB1) is a toxin produced by Aspergillus species of fungi. Findings in the
literature has shown the potential of probiotic treatment to alleviate AFB1 toxicity. This study
explores the effects of Lacticaseibacillus paracasei Shirota (LcS) supplementation on the
growth performance, intestinal health, and excretion of faecal AFB1 metabolite of AFB1-
exposed rats. Thirty-two male Sprague Dawley rats were divided into control, AFB1,
AFB1+LcS and LcS groups. AFB1 was given at a complete dosage of 25 µg AFB1/kg body
weight, while LcS supplementation at 2×109 CFU/mL per day for four weeks. The average
body weight of the AFB1 group showed no significant increase from week 2 to 4, while other
groups had an increment throughout the study. The food intake of the AFB1 and AFB1+LcS
groups had significantly reduced throughout the treatment period. AFB1 exposure caused
several changes in the histomorphometry parameters but was normalised with LcS
supplementation. The AFB1 group showed mild to moderate inflammation in all intestinal parts,
whereas only mild inflammation was observed in the jejunum and ileum of the AFB1+LcS
group. Faecal Bifidobacterium spp. counts showed an increment in three groups, while the
AFB1 group showed a significant reduction. The faecal AFB1 in the AFB1 group was
significantly lower than in the AFB1+LcS group. In conclusion, AFB1 affected growth
performance and intestinal health, and wherein the effects were alleviated by LcS
supplementation. Further investigation on intestinal permeability and serum and urinary AFB1
level is suggested to understand the mechanism of probiotic-AFB1 interaction in alleviating
AFB1 toxicity.
