Abstract
Hygiene-sanitary conditions, the presence of Salmonella spp. and indicator microorganisms of chicken cuts sold on the market in the Recôncavo da Bahia area, are analyzed and their co-relationship with conditions of commercialization is verified. Sixty samples were collected between May and August 2016 at informal selling sites (fairs, butcher shops, abattoirs) and in supermarkets of ten municipalities of the Recôncavo da Bahia region. Hygiene and sanitary conditions were assessed through a check list. Total coliforms, Escherichia coli, mesophylls, psychrotrophic organisms, molds and yeast, and Salmonella spp. were counted. Results revealed statistical difference for total coliforms and Escherichia coli only, featuring greater concentration rates in fairs, butcher shops and abattoirs. Further, 31.7% of samples indicated 31.7% Salmonella spp. and 16.6% of samples failed to comply with sanitary legislation on Escherichia coli. Observational analysis demonstrated that 61.83% and 38.1% of the samples respectively on informal sites and in supermarkets did not comply with legislation and indicated a co-relationship of some variables with the growth of total coliforms, Escherichia coli and mesophylls. Pathogenic and indicator microorganisms suggest flaws in hygiene and sanitary conditions in the commercialization of chicken cuts and health risks to consumers.
Highlights
Chicken meat, highly relevant for human beings, is one of the most sold items in Brazil and worldwide, due to its low fat rate and low costs [1] [2] [3]

Summary
Highly relevant for human beings, is one of the most sold items in Brazil and worldwide, due to its low fat rate and low costs [1] [2] [3]. Data derived from Family Budget Research show that the predominance of chicken meat in Brazil reached 27% when compared to other food items. In spite of high consumption rates, chicken meat is reported to be a vector of microorganisms indicating improper hygiene conditions and even pathogenic microorganisms, such as Salmonella spp. and Escherichia coli. Natura chicken meat ranks ninth among epidemic-causing foods in Brazil [5]. 12 published on 2nd January 2001 [6] on food microbiological standards in Brazil provides the maximum coliform limits (104 CFU/g) at 45 ̊C for in natura chicken meat. Other microorganisms may indicate flaws in the production or commercialization of this type of food
