Turkiye joined EHEDG in 2012. Commencing in mid-2014, Hygienic Design Training and face-to-face hygienic design introduction visits began at the company level by Onur Devres. In 2015, the first three members joined EHEDG from Turkiye.

As stated under GFSI 2020 JI and JII topics, food processing facilities' construction and food processing equipment should be designed and engineered according to hygienic design principles. However, explaining all this to companies and ensuring they understand, accept, and internalize it (and become members and pay the EHEDG membership fees) takes time. Primarily since 2016, visits and briefings have been conducted every year for current, global, and potential members. Consequently, the number of members increased, and existing members continued to stay within EHEDG.

At the end of 2021, Sadef decided to establish a freeze-dryer facility in Aydin. For the design of the facility, Onur Devres and Ugur Uzuner, who had previously received hygienic design training from him, started discussions with architects, constructors, installation engineers, building element manufacturers, refrigeration companies, fruit processing machinery manufacturers, and freeze dryer equipment manufacturers. Positive discrimination was particularly applied to EHEDG members in the selection of subcontractor companies. After creating the preliminary construction project, work began on the placement of devices, installations, and drainage. To eliminate the problems encountered during this period and to ensure better project realization, non-member subcontractor companies were encouraged to join EHEDG and the architects, engineers, and designers from Sadef and subcontractor companies involved in the project attended the EHEDG Advanced Course on Hygienic Engineering and Design.

As of 2024, the construction of the 23,000 m² Sadef company facility has been completed; the number of members has approached 40; and nearly 40 global member companies have participated in EHEDG activities in Turkiye.

The Sadef project has actually been an example of constantly addressing the importance of hygienic design and engineering in a country and observing its development over time on a unique company basis. We believe that this will set a new state in benchmarking for other companies.
