Honey has multiple beneficial properties but polluted environments have led to its contamination. Contaminated honey not only serves as a sentinel of environmental pollution, but can also pose potential risks to consumers’ health. In the present study, QuEChERS (quick, easy, cheap, effective, rugged and safe) method along with gas chromatography coupled to selective detectors (ECD/FTD/MS) was used for determining 24 pesticide residues and/or their metabolites in 150 honey samples collected from markets in Northern India. The method was optimized and validated according to the European Commission’s guidelines. Residues of pesticides were detected in 12% of samples, of which a majority contained organophosphate residues. Assessment of human health risks suggests that contaminated honey at current levels has minimal contribution to toxicological risks. However, precautionary measures should always be taken considering the customary honey feeding in infants and cumulative effect of these chemicals in the foreseeable future. This study highlights the importance of continuous monitoring of pesticide residues, and consumer awareness towards certified products to safeguard public health.Keywords

Aflatoxin M1 (AFM1) is a toxic and carcinogenic metabolite secreted in milk of dairy animals which have consumed the aflatoxin B1 contaminated feedstuff. In this study, 230 different types of milk samples comprising raw, pasteurized and ultra-high temperature treated milk were collected from three different geographical sites of Punjab during different seasons and analysed for the presence of AFM1 by using ELISA as screening, and HPLC with fluorescence detection as confirmatory method. Of total, 51% samples were detected positive for AFM1, while 45% and 38% samples were found with AFM1 levels higher than the tolerance limits established by the European commission and Food safety and standard authority of India respectively. Results of study indicated a high incidence and levels of AFM1 in different types of milk during all seasons. Owing to this, there is a potential risk of liver cancer in people of Punjab, India especially children due to milk consumption. Therefore, strict regulatory actions are urgently required to control AFM1 level in milk below the legal standard limits. There is need to initiate routine examination of dairy animal feeds for aflatoxins to reduce animal and consequently human exposure.Keywords
