EC regulation no. 852/2004 Food hygiene Obligations of the food company Article 1 excerpt: The food company is primarily responsible for food safety. Article 2 excerpt: The term food hygiene refers to measures and precautions ( ) to control risks and to ensure that food ( ) remains safe for human consumption. Article 3 excerpt: The food company shall ensure that the applicable hygiene stipulations of this regulation are complied with in all production, processing, and distribution stages of food under its control. solids solutions group 4

Guideline 2006/42/EG Machine guideline Obligations of the manufacturer / distributor Art. 2 Definition of the term machine : We consider the bulk good facility to be the entirety of machines for executing processing steps, such as storage, transportation, dosage, processing. Art. 5 Distribution and start-up operation: By executing the EC declaration of conformity (...) the manufacturer / distributor confirms, among other things, the compliance with hygiene guidelines according to annex 1 paragraph 2.1 food machines and machines for cosmetic or pharmaceutical products. Here, the company is responsible for the implementation of any and all machines (equipment) for hygiene-conform handling and processing in compliance with the law. solids solutions group 5
