USA – Occurrence of Foodborne Agents at Food Service Facilities in the Czech Republic

Journal of Food Protection

ABSTRACT

The aim of this study was to investigate the occurrence of foodborne agents at food service facilities in the Czech Republic. The sampling, performed from April 2016 to November 2017, focused on the microbiological monitoring of the environment at the establishment (EFS; n = 298) and the hands of staff (HFS; n = 159). The analysis targeted the presence of the following bacteria: Escherichia coli (focusing on the presence of Shiga toxigenic E. coli), Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, Salmonella spp., and Campylobacter spp. A swab method using sterile abrasive sponges was used to detect bacteria in EFS; a glove-juice method was used to monitor microbial contamination on HFS. The presence of E. coliwas confirmed in 11.8% of samples (12.4%, EFS; 10.7%, HFS; P = 0.650). The presence of Shiga toxigenic E. coli was not confirmed in the samples. B. cereus was detected most frequently, in 39.6% of all samples taken (44.6%, EFS; 30.2%, HFS; P= 0.003). S. aureus was detected in 17.9% of samples (17.4%, EFS; 18.9%, HFS; P = 0.703). Of S. aureus isolates, 58.5% were found to be positive for the presence of genes producing staphylococcal enterotoxins (70%, HFS; 52.0%, EFS). L. monocytogenes was detected in only one sample (0.2%; EFS). The presence of Salmonella spp. and Campylobacter spp. was not confirmed. The occurrence of B. cereus, S. aureus, and E. coli was dependent on the season of the year. B. cereus and S. aureus occurred less frequently in the summer months, although E. coli was recorded more frequently. B. cereus, S. aureus,and E. coli were detected in almost half of the tested samples. The relatively high percentage of B. cereus and S. aureusisolates from EFS corresponded with the model in the final European Food Safety Authority reports on the occurrence of foodborne disease outbreaks in the European Union. Managers of food service facilities should focus on reducing the occurrence of B. cereus and S. aureus.

HIGHLIGHTS
  • Contamination of food service facilities in the Czech Republic by foodborne agents was determined.

  • Bacillus cereus, Staphylococcus aureus, and Escherichia coli were detected in almost 50% of samples.

  • The occurrence of B. cereus, S. aureus, and E. coli depended on the season of the year.

  • Regular monitoring of food service facilities for agents of foodborne disease is necessary.
