The Rapid Alert System for Food and Feed (RASFF) was launched 30 years ago. The system has undergone many modifications during this time; it was influenced by development of communication networks and by enlargement of the European Union as well. However, the principle remained the same. Countries which are involved in the system mutually exchange information related to dangerous food and feed present on the European market. When one of the network members detects a dangerous foodstuff on its territory and there is only a suspicion that it might have been distributed to another country, he must promptly notify that country through the system. An authority in charge of that country can then take immediate measures necessary for protection of the consumers‘ health.
