(90)Where economic operators offer the possibility to purchase products through refill, they should ensure that their refill stations meet certain requirements in order to ensure the health and safety of consumers. In that context, where the consumers use their own containers, the economic operators should provide information about the conditions for the safe refill and use of those containers. In order to encourage refill, economic operators should not provide packaging free of charge or packaging that is not part of a deposit and return system at the refill stations. Economic operators should be exempt from liability for food safety problems that could arise from the use of containers provided by consumers.
