The cooling, conditioning, cleaning and packaging stage were recognized as exposed risk product stages, where sampling points were centralized in 4 zones. Within the 4 zones, 28 surface sampling points and 4 air sampling points were identified. Of the 28 surface sampling points, outlier results were found at 7 sampling points this represents 25% incidence. Regarding the microbiological results of histamine-forming bacteria in air samples, no incidence of atypical results was found. Alert and action limits were established for the control of histamine-forming bacteria in surface and air samples, being of great contribution to the food safety system. |
