Tafel Deutschland e.V launched a campaign on best before dates with the support of an agency, which is supporting them with free space in public areas nationwide. This is particularly relevan because of the stockpiling and panic buying that were going on as a result of the pandemic.
The poster is freely available in multiple languages (German, Arabic, English, Farsi, Russian and Turkish) for Tafel member food banks and pantries to order or print.
