Disinfectants are regularly used for cleansing poultry slaughterhouses to control microorganisms. However, the microorganisms
such as bacteria are developing resistance to disinfectant(s) and complicate control of bacterial infections. (e aim of this study was,
therefore, to determine disinfectant susceptibility/resistance patterns manifested by bacteria (to commonly used disinfectants), which
were isolated from intestines of slaughtered indigenous chickens in Nairobi, Kenya. (e method used was agar well diffusion, and the
six disinfectants (their active ingredients are in brackets) tested were as follows: Kupacide® (glutaraldehyde; benzalkonium chloride);
TH4+® (didecyl dimethyl ammonium HCl; dioctyl dimethyl ammonium HCl; octyl decyldimethyl ammonium HCl; alkyl dimethyl
ammonium HCl; and glutaraldehyde); Noro cleanse® (glutaraldehyde; coco-benzyl-dimethyl-ammonium chloride); Dettol®
(chloroxylenol); Savlon® (chlorhexidine gluconate; cetrimide; and N-propylalcohol); and Jik® (sodium hypochlorite). At recommended user concentration by the manufacturer, isolates showed various resistance to the respective disinfectants. E. coli isolates
were resistant to five of the tested disinfectants (Jik®, TH4+®, Noro cleanse®, Dettol®, and Kupacide®); however, they were susceptible
to Savlon®; Staphylococcus isolates were resistant to disinfectants to Jik® and TH4+® and susceptible to the rest disinfectants;
Streptococcus isolates were only resistant to Jik® and susceptible to the remaining disinfectants. Some E. coli and Staphylococcus
isolates showed resistance to more than one disinfectant. (is study has demonstrated resistance of the bacterial isolates to various
disinfectants at recommended user concentrations, although some of them were susceptible at higher concentration(s) and lower
concentrations. (is will interfere with the cleansing of the respective premises, resulting in contaminated products, which may endup causing disease in the humans consuming them. Hence, it is recommended that one ascertains the efficacy of respective
disinfectant by carrying out disinfectant susceptibility testing to know the effective ones and the appropriate concentration to use
