Resumo
Food safety is a premise to public health worldwide. The poultry products are
known as transmitters of important foodborne pathogens, especially Salmonella
sp. The access to poultry products and eggs is cheaper and affordable to various
social classes, which increases the risk to consumers when these products do not
meet microbiological standards. Several studies indicate high prevalence of
human salmonellosis linked to the consumption of chicken meat improperly
processed and contaminated eggs. In aim to evaluate the occurrence of
Salmonella sp. in poultry meat and eggs commercialized in Goiânia, a study was
undertaken using enzyme immunoassay and later confirmation by conventional
bacteria isolation and serotyping. A second objective was to profile the
antimicrobial susceptibility of the isolates. A total of 100 broiler carcasses and 100
dozen of eggs were collected from 20 stores located in seven different health
districts of Goiânia. The results showed the occurrence of Salmonella sp. in 21 %
of carcasses, but egg contamination was not detected in any of samples collected.
The most frequently serovar isolated was Salmonella Schwarzengrund. It was
observed that 100% of the isolates were sensitive to chloramphenicol, norfloxacin,
and amikacin. On the other hand, 62% were resistant to nalidixic acid, 38%
ceftriaxone and ampicillin, and 48% were resistant to trimethoprimsulfamethoxazole.
Finally, 52% of isolates showed intermediate susceptibility to
ciprofloxacin. It was also observed that 42.9% of the isolates showed multidrug
resistance, indicating the possible occurrence of multidrug-resistant serovars in
the municipality of Goiânia and the need for monitoring to avoid the use of drugs
indiscriminately. It can be concluded that the presence of Salmonella enterica in
chicken meat available in Goiânia commerce may expose the population to the
risk of foodborne-diseases by the consumption of improper food.
