Carrot (Daucus carota L.) is a nutrient-rich vegetable that is widely cultivated and consumed in Pakistan in both raw and processed form. Data on the proximate composition and natural occurrence of aflatoxins (AFs) in carrots and marketed carrot products is lacking in Pakistan and the risk exposure of AF has not been characterised before. Thus, the current study was designed to know the frequently consumed carrot products with per capita consumption, and risk assessment of AF through these products in various regions of South Punjab Pakistan. A survey was conducted with 125 respondents and appeared that raw carrot, fresh carrot juice, gajrella and pickle are the most frequently consumed marketed carrot products with per capita consumption i.e. 62.5, 46.6, 16.2 and 14.5 gday-1, respectively. Proximate analysis revealed that carrot root and processed carrot products contained 9.65–98.2% moisture, 0.23–0.60% ash, 6.2–14.1% carbohydrates, 0.31–0.80% protein, 0.40–3.7% fat and 1.4–4.20% fibre. AF analysis revealed that 36.67% of samples were contaminated with TAF. Thirty-five (35%) percent of samples were tainted with aflatoxin B
1 , and 13.33% of samples were contaminated with aflatoxin B2 . All the samples of carrot root, fresh carrot juice and gajrella contained TAF levels less than the maximum limit (ML) (2 ppb) assigned by the European Union (EU). However, the entire AFB1 positive samples of carrot pickle contained AFB1 levels of more than 2 ppb exceeding the ML. Furthermore, daily dietary exposure of TAFs ranged from 0.11 to 1.27 ng/kg of body weight per day which relatively exceeds the permissible limit of 1 ng/kg of body weight per day as defined by the Joint FAO/WHO Expert Committee on Food Additives. This is the first prevalence and risk assessment report of AF in marketed processed carrot products in Pakistan. These baseline data are an initial step in the effort to deal with this significant food safety issue and the establishment of legislation for AF in marketed products is needed in Pakistan.
