Overview
- The ÖKO-TEST April 2026 review, released Thursday, tested 50 wholegrain flours and rated 39 as very good or good.
- Labs flagged some samples for elevated nickel and cadmium, which were below current limits yet raised long-term exposure concerns.
- One flour contained STEC, a harmful E. coli, prompting a two-grade penalty and a warning not to eat raw dough.
- Bio Sonne Dinkel Vollkorn from Norma was the clear failure after raised cadmium and nickel plus mineral-oil residues known as MOSH.
- Rye flours stood out, with every rye product at least good and none showing critical heavy-metal findings.
