Abstract: Increased cases of deaths as a result of taking home made brews/spirits have been a major concern in our country. Recently, many lives have been lost due to the ignorance of the brewers and their patrons. This study was carried out to determine the levels of nitrate in home - made brews, home - made spirits, raw materials and water. Four hundred and forty (440) home - made alcoholic beverages, one hundred and ten (110) water and eighteen (18) raw materials samples obtained from various parts of Nairobi slums and its environs were analyzed for nitrate. UV-visible Spectrophotometry was used in the research. Some samples contained analyte values above limits set. The concentrations of nitrate varied from non detectable (ND) to 46.3 ± 1.404 mg/l. The recommended maximum contamination levels set by KEBS/WHO for nitrate in alcohols is nitrate 50 mg/l. Most of the home made brews and spirits analyzed in this study had values slightly lower than the levels recommended by the World Health Organization. Values of nitrate were observed to be generally high in the brews/spirits and the raw materials used. The raw materials may have contributed in elevating the levels of these pollutants in the brews. These findings are therefore useful since they provide a justified cause for the Kenyan Government to fight the selling of local alcoholic beverages.
