Online survey among a panel of 1,304 French citizens on home practices concerning four store-bought infant foods (powdered infant formula, sterilized vegetable mixed with fish, infant cereals, fruit puree), in relation to infant food safety. The survey is composed of 50 individual questions. The survey was designed using the Limesurvey tool. It was then launched in June 2021 by the Crowdpanel polling company in order to ensure a representative sample of the French population. Answers to the survey are provided in csv format.
