Norwegian security has actually discovered a low level of flour samples favorable for Shiga toxin-producing E. coli (STEC).
The Norwegian Food Safety Authority (Mattilsynet) commissioned a study of STEC in wheat flour to collect information on the issue.
An overall of 151 samples of flour were gathered from sellers in 2021 and examined in 2022. Enriched samples were analyzed for the existence of picked hereditary markers. Efforts to separate STEC were performed from samples that were favorable for Shiga toxic substance (stx) 1 and/or stx2. Separates determined as STEC were even more identified utilizing entire genome sequencing.
STEC was separated from 3 samples. They were determined as STEC O187: H28, O155: H21, and O154: H31 and none of the isolates harbored the eae gene.
There is very little literature on how flour is infected and about its microbiological quality, although some research studies have actually been done.
Outcomes revealed that the event of STEC in flour on the Norwegian market was low. STEC was separated, it didn’t have actually virulence genes associated with a major infection or belong to the serogroups most typically associated with the illness.
Such items had actually not been examined in Norway formerly and regardless of the low variety of samples evaluated, findings supply standard understanding for the indus
