5 The precautionary principle At Semper the precautionary principle means that we are always better safe than sorry. The precautionary principle is applied since we develop food for infants and young children that consume more food per kilo bodyweight than adults, while being more sensitive to unwanted substances. It is also applied since we develop, produce and market gluten-free food for people with celiac disease, or need to avoid gluten for other reasons. We stand for Safety, which of course applies to all foods we offer.
