Every consumer is entitled to safe food that is produced, packaged, labelled and sold in accordance with the current standard. Foodstuffs can be contaminated by pathogenic microorganisms that can cause specific diseases. Intentionally or unintentionally adding an excessive quantity of certain ingredients/substances to foodstuffs may also pose a risk to human health. Raw materials are sometimes also naturally contaminated or contaminated by hazardous compounds via the environment or through agricultural practices. Food preparation methods can sometimes also cause the presence of unwanted compounds. Food labelling also plays an essential role in protecting consumer health. False or misleading information, or the absence of allergen labelling, may have unpleasant consequences. Public authorities have a duty to protect consumer health. To this end, food standards have been laid down at both national level and European level. It is important that food business operators comply with those standards.
