In vitro efficiency of disinfectants against salmonella enteritidis samples isolated from broiler carcasses

Abstract

The threat to public health represented by Salmonella is at least partially a consequence of its ecology in poultry hosts. Good manufacturing practices in the processing plant can reduce the contamination of poultry products, and critical control point principles are essential throughout the chain production. One procedure adopted in critical points control to prevent and to reduce Salmonella in farms and poultry products is the use of disinfectants. This study aimed at evaluating disinfectant efficiency against Salmonella enteritidis samples isolated from broiler carcasses in Rio Grande do Sul State between 1995 and 1996. The tested disinfectants were: phenol 1:256, quaternary ammonium 1:2500, glutaraldehyde 1:200, and iodine 1:500, with contact times of 5, 10, 15, and 20 in an in vitro test. .Phenolic compounds showed better results, iodine and glutaraldehyde showed intermediary results, and quaternary ammonium presented efficiency at all contact times evaluated in the in vitro test.

Comparative Evaluation of the Effects of Binzalkonium Chloride, Iodine, Gluteraldehyde and Hydrogen Peroxide Disinfectants against Avian Salmonellae Focusing on Genotypic Resistance Pattern of the Salmonellae Serotypes toward Benzalkonium Chloride

“…Hydrogen peroxide vapor (HPV) showed excellent disinfection ability against Salmonella Typhimurium, E. coli and Listeria monocytogenes with dependency on concentration and time of exposure (Back, 2014).The cationic surfactants, like quaternary ammonium compounds, exert their activity by disrupting the bacterial membranes but some indicators pointed effects against the cytoplasmic components (Chapman, 2003), particularly when using high concentrations (Lambert, 2008). Salmonella Enteritidis isolates Quaternary ammonium was effective against Salmonella Enteritidis isolates during all contact times (Cardoso et al, 2008). Formulations of disinfectants containing quaternary ammonium compounds (QACs) including benzalkonium chloride have poor effects against gram-negative bacteria, coliforms, and spores (Wales et al, 2006).…”

Commonly Used Disinfectants Fail To Eradicate Salmonella enterica Biofilms from Food Contact Surface Materials

“…However, a number of authors have described Salmonella biofilm formation with a limited number of strains (30,31), with a single serovar (16,18,26,(32)(33)(34)(35)(36)(37), or by using a single biofilm substratum (29,(38)(39)(40)(41). There have also been significant studies in this regard related to other genera of bacteria, notably Listeria monocytogenes (42)(43)(44).…”
