14. Storage and distribution

14.1 Packaged dried medicinal plants/herbal drugs, including essential oils, should be stored in a dry, well-aerated building, in which daily temperature fluctuations are limited and good aeration is ensured. Fresh products should be stored between 1°C and 5°C while frozen products should be stored below -18°C (or below -20°C for long term storage).

14.2 In the case of bulk transport, it is important to secure dry conditions. Furthermore, in order to reduce the risk of mould formation or fermentation it is advisable to use aerated containers. As a substitute, the use of sufficiently aerated transport vehicles and other aerated facilities is recommended. Essential oil transport must conform with appropriate regulations. Regional and/or national regulations on transport have to be respected.

14.3 Fumigation against pest attack should be carried out only where necessary and must be carried out exclusively by licensed personnel. Only registered chemicals must be used. Any fumigation against pest attack should be reported in the documentation.

14.4 For fumigation of warehouses, only substances permitted by the regional and/or national regulations should be used.

14.5 When frozen storage or saturated steam is used for pest control, the humidity of the material must be controlled after treatment.
