Are Modern Varieties of Wheat Linked to The High Number of People with Wheat Issues? Probably Not

With what seems to be an increasing number of people having issues with wheat, mostly gluten from the wheat, researchers looked to see whether this increase was related to modern varieties of wheat.  Looking at 120 years of wheat (taken from historical archive of wheat samples), investigators determined that this is not related.

"Analyses by the team of scientists show that, overall, modern wheat varieties contain slightly less protein than old ones. In contrast, the gluten content has remained constant over the last 120 years, although the composition of the gluten has changed slightly. While the proportion of critically viewed gliadins fell by around 18 percent, the proportion of glutenins rose by around 25 percent. In addition, the researchers observed that higher precipitation in the year of the harvest was accompanied by a higher gluten content in the samples." 

 "Surprisingly, environmental conditions such as precipitation had an even greater influence on protein composition than changes caused by breeding. In addition, at least on the protein level, we have not found any evidence that the immunoreactive potential of wheat has changed as a result of the cultivation factors," explains Katharina Scherf, who is now continuing her research as a professor at the Karlsruhe Institute of Technology (KIT).

Snack Items Recalled After Supplier's Supplier Has Peanut Allergen Cross Contact Issue

Frito Lay and Hostess announced recalls of a number of their flour containing snacks after their supplier found that peanut allergen may be present in the flour they provided.  That supplier, Grain Craft, announced that the issue came from one of their suppliers, a flour mill in Georgia (where there are plenty of peanuts).  Hostess has reported two potential allergen issues, Frito Lay has not had any reports of issues.
 Grain Craft stated in their press release:

"These recent recalls bring to light the challenge of agricultural cross-contact, which is the result of customary methods of growing, harvesting and shipping of wheat and other agricultural products."

So was Grain Craft managing peanut allergen as a potential hazard?  It was not stated in their press release [attached below].

 

So if your company is buying bulk wheat flour, good time to assess whether peanut allergen can be a risk.  Part of that will be checking with the supplier to see if they are controlling allergens as part of their food safety procedures, especially when they are sourcing their product from various mills.

Gluten Free Cheerios Recalled Due to Transportation Error that Caused Contamination

General Mills is recalling 1.8 million boxes of gluten-free Cheerios after FDA received 125 complaints from people having an adverse reaction, primarily gastrointestinal issues associated with celiac disease, an extremely painful disorder triggered by the ingestion of gluten.

According to the report - "The company said Monday the foul-up occurred when the Lodi plant lost rail service and its gluten-free flour was transferred from rail cars to trucks.....General Mills said oat flour was contaminated when bulk rail cars full of the stuff were offloaded into bulk trucks, Foster said. The bulk trucks were believed to recently have carried wheat, she said."
An incredible error for a product purchased specifically because it is supposed to contain no gluten.

It is important to see how a monumental error can occur when responding to a crisis. In this case, people worked around the loss of rail service only to contaminate product by not considering the gluten issue in the stopgap measure - off loading into uncleaned transport vehicles.

Untrained logistics/transportation people?  This is a reminder of ensuring that all people within the organization are trained in food safety - both general food safety as well as the food safety issues specific to the activities that with which they are tasked.

From Celiac.org
https://celiac.org/celiac-disease/what-is-celiac-disease/
Celiac disease is an autoimmune disorder that can occur in genetically predisposed people where the ingestion of gluten leads to damage in the small intestine. It is estimated to affect 1 in 100 people worldwide. Two and one-half million Americans are undiagnosed and are at risk for long-term health complications

When people with celiac disease eat gluten (a protein found in wheat, rye and barley), their body mounts an immune response that attacks the small intestine. These attacks lead to damage on the villi, small fingerlike projections that line the small intestine, that promote nutrient absorption. When the villi get damaged, nutrients cannot be absorbed properly into the body.

FDA says it received 125 complaints about gluten-free Cheerios before recall
General Mills said it knows how the gluten got into its flour and has taken steps to prevent it.

Federal food regulators said Tuesday they have received 125 reports of adverse health effects — mostly gastrointestinal problems — from consumers who ate gluten-free Cheerios.

After hearing of such complaints, General Mills Inc. on Monday recalled 1.8 million boxes nationwide of gluten-free Cheerios and Honey Nut Cheerios, concluding they inadvertently contained wheat, which contains gluten.
