Research – Deoxynivalenol and ochratoxin A in North Carolina grown organic wheat grains

Wiley Online

Abstract

The main safety issue of cereal grains is mycotoxin contamination. There is no published information about mycotoxin contamination of organic wheat in the United States. This study quantified the contents of deoxynivalenol (DON) and ochratoxin A (OTA), two frequently occurring mycotoxins, in organic wheat samples collected from six counties in North Carolina by enzyme‐linked immunosorbent assay (ELISA) and high‐performance liquid chromatography (HPLC). By ELISA, all samples were DON and OTA positive, and the DON contents in the flour and bran samples were 0.7–2.35 ppm and 5–8 ppm, respectively, while OTA in the flour and bran samples were 9.54–25.55 ppb and 21.67–32.55 ppb, respectively. By HPLC, the DON detected in flour and bran were 0.24–0.47 ppm and 0.35–0.83 ppm, respectively; all flour samples were OTA negative, but 5 out of 6 bran samples were OTA positive (0.48–1.28 ppb). More studies with larger sample number are needed to obtain representative results.

Practical applications

This study provides preliminary results about the DON and OTA in organic wheat grains. The results indicate that the organic wheat produced in North Carolina during 2018 season were contaminated by DON and OTA to various degrees. However, the concentrations of these two mycotoxins determined by ELISA were significantly higher than those determined by HPLC. Therefore, to avoid overestimation or underestimation, it is important for researchers and regulatory agencies to conduct multi‐lab studies to develop and standardize analytical methods and detailed procedures for accurate DON and OTA quantification. Regardless of analytical methods, all bran samples showed higher DON and OTA concentrations than flour samples. Thus, when using organic wheat bran or whole wheat as food or feed ingredients, the level of bran inclusion should be controlled to protect consumers and animals from mycotoxicosis.

UK – Class 2 Medicines Recall: Bisacodyl 5mg Gastro-Resistant tablets batch 25074A (MDR 34-04/19) – Recalled Moulds

Gov UK

Chanelle Medical is recalling the above batch because a small number of packs have been found to contain tablets which are stuck together, with mould observed on some tablets. The mould has been identified as a Penicillium species. It is unlikely that affected tablets will have got to patient level as the sticking is noticeable on opening the pack.

USA – Florida: Hepatitis A positive employee at Pizza Hut – also, unwashed hands, mold and odor of sewage

Food Poison Journal

A joint inspection was conducted on June 11 by the state and the Pinellas County Health Department after a pizza maker tested positive for the contagious disease on June 3. The Pizza Hut at 2421 4th Street North in St Petersburg is the latest restaurant to have a confirmed case of Hepatitis A.

During that food safety inspection, the state found employees not properly washing their hands after handling dirty dishes in the dish area and then unloading clean dishes from the dishwasher.

They also discovered mold on the pizza make cooler, an objectionable odor of sewage in the kitchen near the pizza oven and black mold on the walls.
