Evaluation of the Effect of the Technical Guidelines for Chilean Milk Dietary Service on the Microbiological and Nutritional Quality of a Powdered Infant Formula

The Chilean Technical Manual for Milk Dietary Service (SEDILE) was evaluated to determine its effectiveness in ensuring the microbiological safety and vitamin D adequacy of a commercially available powdered infant formula (PIF) used in SEDILE. The evaluation focused on whether adherence to the manual’s guidelines positively influenced these factors. Both the PIF and the reconstituted PIF (RIF) were found to be free from Cronobacter sakazakii and Salmonella enterica contamination, with levels of total coliforms and Escherichia coli within acceptable limits. Moreover, the vitamin D content in the formula was within the expected range. These findings suggest that following the Chilean Technical Manual for SEDILE contributes to the microbiological safety and nutritional adequacy of RIF in dietary services.
