The aim of the study was to assess the effect of inadequate transport on the result of microbiological analyses of minced meat in modified atmosphere (MAP). During transport minced meat must be kept at a temperature below 2 °C (Regulation (EC) No 853/2004). Minced beef and beef/pork mixture was packaged in modified atmosphere (MAP) for the purposes of the experiment. The model experiments simulated an increase of temperature during the transport to 5, 8, 11, 14, 17, 20 and 25 °C. The exposure time was 1, 2, 3, 3,5 and 4 h. The aerobic plate count (APC) in the samples were determined immediately after exposure to higher temperature (0 h), 3 h and 24 h after returning to the adequate temperature (2 °C). The APC values were influenced by temperature and by duration of exposure to higher temperature. It is necessary to analyse the samples immediately after receiving them in the laboratory. The results of this sub-study enabled the creation of software that recommends or does not recommend to laboratories the microbiological analysis of a food sample of animal origin due to disruption of the cold chain during its transport (https://webstudio.shinyapps.io/transportvzorku/).
