We describe a Poona outbreak involving 31 infant cases in France. Following outbreak detection on 18 January 2019, consumption of rice-based infant formula manufactured at a facility in Spain was identified as the probable cause, leading to a recall on 24 January. Whole genome sequencing analysis linked present outbreak isolates to a 2010-11 Poona outbreak in Spain associated with formula manufactured in the same facility, indicating a persistent source of contamination.

Background: Omega-3 long chain polyunsaturated fatty acids (LCPUFAs) are important dietary components for maternal and infant health during pregnancy and lactation.

Objective: This study investigated determinants of maternal and infant LCPUFAs status at three months postpartum and the relationship between maternal serum, mother's milk, and infant LCPUFAs.

Methods: This cross-sectional study included mothers (n=1481) and their offspring (n=526) at three months postpartum from the APrON cohort.

Background: Food protein-induced allergic proctocolitis is a nonimmunoglobulin E-mediated, self-limited food allergy of the rectum and the colon. Cow's milk protein is the most common allergen responsible for the disease.

Objective: This study aimed to investigate the roles of different types of formulas in building early tolerance to food protein-induced allergic proctocolitis in infants.

The nutritional environment during fetal and early postnatal life has a long-term impact on growth, development, and metabolic health of the offspring, a process termed "nutritional programming." Rodent models studying programming effects of nutritional interventions use either purified or grain-based rodent diets as background diets. However, the impact of these diets on phenotypic outcomes in these models has not been comprehensively investigated.

Despite the WHO recommendations in favor of breastfeeding, most infants receive infant formulas (IFs), which are complex matrices involving numerous ingredients and processing steps. Our aim was to understand the impact of the quality of the protein ingredient in IFs on gut microbiota and physiology, blood metabolites and brain gene expression. Three IFs were produced using whey proteins (WPs) from cheese whey (IF-A) or ideal whey (IFs-C and -D) and caseins, either in a micellar form (IFs-A and -C) or partly in a non-micellar form (IF-D).
