Microbiological quality of trahira fish (Hoplias malabaricus) from Baixada Maranhense, municipality of São Bento, MA

Abstract

Fish are considered rich sources of nutrients. Health care throughout its production chain aims to ensure quality, minimizing the risks of transmission of foodborne diseases. In order to evaluate the microbiological quality of trahira fish (H. malabaricus), 40 samples were analysed for Most Probable Number (MPN) of coliforms at 45ºC, counts of aerobic mesophilic bacteria and Staphylococcus spp., identification of E. coli, Salmonella spp. and Aeromonas spp.. Analyses were conducted according to official methods, procedures, and recommendations. Microbiological results showed coliform values at 45 °C ranging from <3 to > 1.1 × 103 MPN/g, presence of E. coli in 14 (35%) samples, counts of mesophilic aerobic bacteria from 9 × 102 to 109 CFU/g and absence of coagulase positive Staphylococcus aureus. Salmonella spp. was detected in 2 (5%) samples, which is in disagreement with the standards required by the RDC Nº 12 of January, 2001 (ANVISA) regarding Aeromonas spp. In total, 36 (90%) samples were contaminated, 7 (19.4%) by A. cavie and 29 (80.6%) by A. hidrophila. The results of this research showed unsatisfactory hygienic and sanitary conditions of fish from the municipality of São Bento (MA), exposing consumers to the risk of foodborne diseases.

Influence of Organic Matter from Native Fish on the Antimicrobial Efficacy of Sodium Hypochlorite (NaClO) in Reducing Salmonella spp. Population

“…Additionally, it is the second most common Salmonella serotype in Europe [18]. An epidemiological study of Salmonella typhimurium in Brazil, covering clinical samples and foods (poultry, chicken, pork and beef), was conducted in the regions of São Paulo, Santa Catarina, Paraná, Mato Grosso do Sul, Rio Grande do Sul, Goiás and Bahia [15,[19][20][21]. However, studies on fish are reported only in the states of Mato Grosso and Maranhão [15,20,21].…”

In the study by [15], the Typhimurium serotype was detected in samples collected at a fish slaughterhouse during the transportation, washing with chlorinated water, evisceration, skinning and filleting stages.…”

Defumação da traíra (Hoplias malabaricus) como método alternativo de conservação

“…É uma espécie neotropical pertencente à família Erythrinidae, sendo frequentemente utilizada para consumo humano, apresentando características produtivas desejáveis como adaptabilidade, alta taxa de proliferação e crescimento (LOZANO et al, 2014). Além disso, a traíra apresenta bom rendimento de carcaça e alta qualidade de carne, características que poderiam classificá-la como uma espécie alvo para a criação em cativeiro (GUIMARÃES et al, 2017;REIS et al, 2017).…”

“…).Destes microrganismos mencionados, no estado do Maranhão, daSilva Lopes et al (2012) relataram a presença de Aeromonas hydrophila em 45,24% das amostras de pescada amarela, Cynoscion acoupa desembarcadas em São Luís Ferreira et al (2014). relataram A. hydrophila em 15% das amostras de peixe serra, Scomberomerus brasiliensis, desembarcados no município de Raposa Guimarães et al (2017). também relataram a ocorrência das espécies A. cavie e A. hydrophila em 90% dos peixes analisados, além de Salmonella spp.…”
