The current research work aimed to access the contamination level of aflatoxins B1, B2, G1, and G2 in the household spices that are widely consumed in huge amounts. 200 different spice samples, 100 packed and 100 unpacked, were analyzed for the aflatoxins profile by HPLC with an incidence of 61.5% contamination out of which 53.66% samples exceed the EU limit. The results disclosed that the unpacked samples are more contaminated as compared to the packed samples except for white cumin seeds. Among packed and unpacked samples of spices, the maximum value of aflatoxins was detected in fennel, that is, 27.93 μg/kg and 67.04 μg/kg, respectively. The lowest concentration of aflatoxin was detected in cinnamon in packed form (0.79 μg/kg) and in the unpacked samples of white cumin seeds which is 1.75 μg/kg. Caraway seeds and coriander in its unpacked form showed positive results whereas black pepper (packed and unpacked) was found free from aflatoxins. This is the first report on the occurrence of aflatoxins in packed and unpacked samples of spices from Pakistan. To ensure safe consumption of spices, there should be constant monitoring of aflatoxin and more studies need to be executed with the intention of preventing mycotoxin accretion in this commodity.
The present overview was intended to evaluate the degree of total aflatoxins and ochratoxin A contamination in different samples of bitter, dark, milk, and white chocolates marketed in Pakistan. For that exploration, two hundred ( = 200) samples of chocolates, 100 branded and 100 local, were analyzed for mycotoxins profile by HPLC-FLD. The outcomes firmly sustained that the majority of the samples were contaminated with aflatoxins and ochratoxin A. The incidence of total aflatoxins and ochratoxin A in branded samples was 83% and 90%, whereas the local samples showed 91% and 97% contamination, respectively. The highest amount of total aflatoxins was found in branded dark chocolates, that is, 2.27 g/kg, and maximum ochratoxin A level was detected white chocolates (2.06 g/kg). On average, the local white chocolates and dark chocolates faced the highest level of total aflatoxins (3.35 g/kg) and ochratoxin A (3.48 g/kg), respectively. The local samples of chocolates were more contaminated with mycotoxins as compared to branded ones accredited to the lack of quality control and quality assurance during the manufacturing as well as packing processes. In recent years, consumption of chocolate is rapidly increasing especially by young generation, so monitoring of mycotoxin occurrence in them is a matter of great concern and more studies are required to comprehend the production of mycotoxins in these products.
Milk products with aflatoxin M1 (AFM1) contamination are a lethal dilemma worldwide due to their carcinogenic and mutagenic effects especially in developing countries. This study investigated the occurrence of AFM1 in milk-based mithae samples marketed in Lahore, Pakistan. Two hundred (n = 200) different types of mithae samples were analyzed for AFM1 using a HPLC florescence detector. Results showed that AFM1 was present in 76% of the analyzed samples, of which more than 80% had a much higher level of AFM1 than the European Union permissible level of i.e.0.05 μg/kg in milk products. The aflatoxin M1 in all the tested samples was observed in the range of 0.004 to 1.49 μg/kg. On average, the Gulab Jamun and Malai Laddu showed the highest level of aflatoxin M1 i.e. 1.49 and 1.17μg/kg, respectively. The lowest amount of aflatoxin M1 was found in Kalakand samples 0.004μg/ kg. The conclusion drawn from this data revealed that almost three-fourths of the mithae samples were highly contaminated with AFM1 due to their main component, milk. The consumption of milk-based mithae is popular due to health benefits as well as being part of tradition. Instead of being nourishing and beneficial, it is been found to be hazardous to human health due to aflatoxin contamination. Continued monitoring of aflatoxin M1with strict rules and regulations is required to prevent aflatoxin accumulation in this favorite food commodity.
