Microbiological Characterization of Baru Nuts From the Cerrado Biome, Brazil

CFU/g. Identification of 17 species from the Enterobacteriaceae family revealed potentially pathogenic microorganisms that serve as important biological markers, including emerging and multidrug-resistant species. Franconibacter pulveris was the most abundant, representing 41.9% of all isolates, followed by Pseudescherichia vulneris and Pantoea septica, each accounting for 10.5%. In addition, Cronobacter sp. (3.8%) and Salmonella sp. (1.0%) were identified-both pathogens commonly associated with nuts and low-water-activity products. The presence of these sanitation-relevant and understudied species highlights the need for ongoing microbiological monitoring and a better understanding of the microbial ecology in food products. PRACTICAL APPLICATIONS: This study provides information on the microorganisms found in baru nuts. These results can help producers improve handling and processing practices, contributing to safer products for consumers and supporting the development of quality standards for this native Brazilian nut.
