Insights
Ready-to-eat chewing substances containing areca nut are microbiologically contaminated with aflatoxins, a carcinogen. This poses a public health risk, especially to children, necessitating preventative strategies.
Area of Science:
- Food safety
- Microbiology
- Public health
Background:
- Areca nut-containing chewing substances are widely accessible.
- Vulnerable populations, including children, are at risk of exposure.
- Microbiological and toxicological profiles of these products require investigation.
Purpose of the Study:
- To assess microbiological contamination in areca nut-based chewing products.
- To quantify levels of fungal aflatoxins in these substances.
- To evaluate potential health risks associated with their consumption.
Main Methods:
- A pilot study analyzed 12 samples of supari, paan masala, and gutka.
- Microbial contamination was assessed using the pour-plate method.
- Fungal aflatoxin levels were determined via enzyme-linked immunosorbent assay (ELISA).
Main Results:
- All 12 products (100%) contained high levels of fungal aflatoxin (0.43-1.84 mg/kg).
- Wet gutka samples showed contamination with Escherichia coli and Enterobacteriaceae.
- One sample (8.33%) failed to meet hygiene standards; no pathogenic bacteria were found.
Conclusions:
- Consumption of unhygienic chewing substances with fungal toxins is a significant public health concern.
- Preventative measures and behavior-change strategies are crucial.
- Addressing the contamination of these readily available products is essential for child health protection.
Objective:
To evaluate microbiological contamination of areca nut-containing, ready-to-eat chewing substances easily accessible to vulnerable paediatric population.
Methods:
A pilot study was conducted at the Aga Khan University Medical College from June to October 2016 on twelve samples of areca nut-containing chewing substances (four supari, paan masala and gutka each) collected from various localities of Karachi. These were evaluated individually for total colony counts, hygiene indicator organisms, pathogenic organisms, and levels of aflatoxin. Microbial contamination was analysed using pour-plate method. Fungal aflatoxin levels were measured by enzyme-linked immunosorbent assay (ELISA)..
Results:
Wet gutka preparations were contaminated by Escherichia coli and Enterobacteriacaea. High levels of fungal aflatoxin (range: 0.43-1.84 mg/kg), a proven carcinogen, were identified in all the 12(100%) products. No sample contained pathogenic bacteria. However, 1(8.33%) sample did not meet hygiene criteria cut-off.
Conclusions:
Habitual use of unhygienic chewing substances containing fungal toxins is a public health concern that needs to be addressed through a preventative, behaviour-changing strategy..
