Results: We identified six case-patients (four females), with two deaths (CFR: 33%). Median age was 53.5 years (range: 35-61 years). Five were members of same household (attack rate: 83%), the sixth was a visitor to the household. Case-patients presented with sweating (100%), dizziness (100%), diarrhoea (100%), and vomiting (83%). Household sourced drinking water from a standpipe in the neighbours’ compound. No cases arose from neighbours’ compound. Water samples from household storage containers revealed 650 µg/l (compliance standard - &amp;lt;70µg/l) cyanide, 414000 µg/l (compliance standard - 100CFU total coliforms (compliance standard – not to be detected in 100ml of water [ND]), and &amp;gt;100CFU fecal coliforms (compliance standard –ND) and &amp;gt;100CFU Escherichia coli (compliance standard –ND).  Water samples from standpipe had &amp;lt;70 µg/l cyanide and 100CFU total coliforms, &amp;gt;100CFU fecal coliforms, and &amp;gt;100CFU Escherichia coli.
