U.S. Wheat Acreage Plummets to 110 Year Low
Jefferson Adams posted an article in Additional Concerns
Celiac.com 11/11/2019 - Plantings of U.S. wheat crops are in steep decline. Abundant supplies, low prices, and competition from global suppliers are driving a decline in US wheat production to levels not seen since William Howard Taft was president, in 1909. A Bloomberg survey of six major market analysts projects a decline in planted acres of all varieties of winter wheat to 31.118 million, down from 31.159 million a year ago and barely above the 29.196 million acres planted 1909, the first year the USDA kept records. Current futures for hard red winter wheat are down about 15% for 2019, one of the worst commodity performances for the year. In some parts of the southern U.S., wheat is now cheaper than corn, giving farmer plenty of incentive to ditch wheat for corn, or other alternatives, like sorghum. “The price doesn’t get high enough to tell us to keep planting wheat,” said Ken Horton, who grows wheat, corn and sorghum with his sons in Leoti, Kansas. Horton is cutting plantings of the HRW wheat variety by 30% to about 3,000 acres. “Any time you have cash corn higher than cash wheat, you’ll see more acres go to corn,” Horton said in a telephone interview. The decline in U.S. wheat planting follows the rise in popularity of gluten-free, wheat-free foods among consumers, which has greatly outpaced the numbers of people with celiac disease or gluten-intolerance.

Quality Management in the Production of Gluten-Free Food
Leszek Jaszczak posted an article in Summer 2012 Issue
Celiac.com 12/01/2017 - Celiac disease is a genetically determined disorder in which affected individuals show an intolerance to ingested gluten (Food Safety Authority of Ireland [FSAI]). It is an inheritable, life-long disease and is characterized by an inflammatory reaction to dietary gluten in the human small intestine. The special feature of the disease is a flattening of intestinal villi along with crypt hypertrophy. As a result, it leads to significant loss of absorptive surface area and resulting malabsorption of nutrients, vitamins and minerals. Untreated celiac disease may be found in the context of symptoms like: anemia, bone diseases, infertility, neurological problems, cancer and other complications due to persistent inflammation and micronutrient deficiencies. Approximately 1% of the United States population has the disease, which is similar to its frequency in the United Kingdom. Only about 10% of affected individuals have been diagnosed thus far [Kagnoff MF (2007) Celiac disease: pathogenesis of a model immunogenetic disease. J Clin Invest 117: 41–49]. At present, the only suitable treatment is strict, life-long exclusion of gluten from the patient's diet. Although a large fraction of patients who attempt to follow such a diet still exhibit signs or symptoms of active disease, there is no available supplementary therapy for such conditions [Ehren J, Morón B, Martin E, Bethune MT, Gray GM, et al. (2009) A Food-Grade Enzyme Preparation with Modest Gluten Detoxification Properties. PLoS ONE 4(7): e6313. doi:10.1371/journal.pone.0006313]. Gluten is defined as a protein fraction from wheat, rye, barley, oats or crossbred varieties and derivatives thereof. Some persons are intolerant to this group of proteins that are insoluble in water and 0,5 M sodium chloride solution [Commission Regulation (EC) No 41/2009 concerning the composition and labeling of foodstuffs suitable for people intolerant to gluten. Official Journal L 16/09 21 January 2009]. To address this problem, the food industry is developing new products for people affected by celiac disease. These new foods are very helpful in diversifying the celiac diet. More available products will increase nutrient consumption, including fiber and minerals, which are often lacking in restrictive diets. Production of gluten free products involves the fulfillment of specific requirements. These products must be free of gluten, which is present in most components of confectionery production. Labeling of the final product is subject to the European Community Commission Regulation No 41/2009 of 20 January 2009, which sets conditions that must be fulfilled by manufacturers. The composition and labeling of foodstuffs suitable for people who are intolerant to gluten is divided into two categories of products according to the nutritional purpose: Gluten free for people intolerant to gluten, and very low gluten content [Wojtasik. A, Daniewski W., Kunachowicz H., 2010. Ocena wybranych produktów spożywczych w aspekcie możliwoÅ›ci ich stosowania w diecie bezglutenowej. Bromat. Chem. Toksykol., XLIII, 2010, 3, str. 362-371]. Selected paragraphs of these labeling rules are quoted below: Foodstuffs for people intolerant to gluten, consisting of or containing one or more ingredients made from wheat, rye, barley, oats or their crossbred varieties which have been especially processed to reduce gluten, shall not contain a level of gluten exceeding 100 mg/kg in the food as sold to the final consumer. The labeling, advertising and presentation of the products referred to in paragraph 1 shall bear the term ‘very low gluten'. They may bear the term ‘gluten-free' if the gluten content does not exceed 20 mg/kg in the food as sold to the final consumer. Oats contained in foodstuffs for people intolerant to gluten must have been specially produced, prepared and/or processed in a way to avoid contamination by wheat, rye, barley, or their crossbred varieties and the gluten content of such oats must not exceed 20 mg/kg. Foodstuffs for people intolerant to gluten, consisting of or containing one or more ingredients which substitute wheat, rye, barley, oats or their crossbred varieties shall not contain a level of gluten exceeding 20 mg/kg in the food as sold to the final consumer. The labeling, presentation and advertising of those products shall bear the term ‘gluten-free'. Where foodstuffs for people intolerant to gluten contain both ingredients which substitute wheat, rye, barley, oats or their crossbred varieties and ingredients made from wheat, rye, barley, oats or their crossbred varieties which have been especially processed to reduce gluten, paragraphs 1, 2, and 3 shall apply and paragraph 4 shall not apply. The terms ‘very low gluten' or ‘gluten-free' referred to in paragraphs 2 and 4 shall appear in proximity to the name under which the food is sold. To achieve gluten content as described above, special conditions in work environment must be instituted. Preparation of high quality products that are safe for people affected by celiac disease, the production process must be controlled not only at the production plant. Origin, breeding, harvesting, storage and transport of ingredients must be also taken into account. The best way to ensure the customer about the safety of a given product is to implement a specially designed quality management plan from the very first step of production. In order for products to be gluten-free or reduced in gluten when they reach the consumer, the gluten-free quality of the product must prevail at every stage of production. Cross contamination is the process by which a reduced-gluten or gluten-free product loses that status. It has come into contact with something that is not gluten-free. Cross contamination may happen during primary production, harvesting and storage of grain, during the manufacture of gluten-free or reduced gluten food in the same plant where gluten-containing food is produced. Cross contamination may also occur as a result of poor re-work, incorrect formulation, product carry-over due to use of common equipment, clean-up or sanitation, poor equipment design, human error or the presence of gluten products near exposed product lines. Potential risks, preventative measures and critical control points need to be identified in the handling of ‘gluten-free' or ‘very low gluten' products. (Deibel, Kurt, Tom Trautman, Tom DeBoom, William H. Sveum, George Dunaif, Virginia N. Scott, and Dane T. Bernard. 1997. A Comprehensive Approach to Reducing the Risk of Allergens in Food. Journal of Food Protection. Vol. 60, No. 4: 436-441) Raw Materials Origin To minimize risk, producers of raw ingredients have to implement appropriate control practices during crop production, harvesting and storage. Plants should originate from certified seeds which guarantees a high level of species purity. Cleaning of sowing machines is also important because seeds from the previous planting can contaminate new crops. The same rule applies to equipment used for harvesting and transportation. Storage areas should be thoroughly cleaned before filling with new crops. Every magazine should be identifiable and people responsible for crop delivery must be informed and instructed to maintain a gluten free workplace. Producers should produce representative samples for laboratory analysis to verify their product's "gluten free" status. Even on the first level of food production, which is plant growing, training and supervision of employees and producers is critical for maintaining the non gluten status of raw materials. Good training of all staff working at these first stages will help to avoid potential sources of food allergens. This type of training should increase awareness about food allergens and the consequences of unintentional consumption by allergic persons. Workers should be encouraged to report any suspected breaches of protocol to their supervisors and suggest possible improvements [Australian Food and Grocery Council, Food Industry Guide to Allergen Management and Labelling - 2007 Revised Edition]. Transport Suppliers of raw materials are obligated to have good allergen management practices to minimize the risk of cross contact between raw materials. Suppliers should provide information identifying any products that contain allergens, the origins of allergenic materials, or those that are likely to cross contamination with allergens. Vendor audits are recommended to verify and explore potential contact with allergenic substances [Australian Food and Grocery Council, Food Industry Guide to Allergen Management and Labelling - 2007 Revised Edition]. Storage Manufacturing plants should be designed to accommodate all aspects of the quality control and allergen management plan,. Storage of raw materials should prevent mixing allergens with non allergenic ingredients. To meet this condition, allergenic materials should be kept at separate facilities, or when this is impossible, all raw materials should be covered to avoid allergenic dust contamination. Clear and visible labeling of containers and all equipment should also be implemented. Tools and equipment used for different materials must also be kept separate [Guidance Note No. 24 Legislation on ‘Gluten-free' Foods and Avoidance of Cross-contamination during Manufacture of ‘Gluten-free' or ‘Very Low Gluten' Products Published by: Food Safety Authority of Ireland 2010, ISBN 1-904465-71-4]. Production To minimize the risk of unintentional contamination of products good manufacturing practices – the Good Manufacturing Practice (GMP) and Hazard Analysis and Critical Control Points (HACCP) plan must note all specific conditions. The production plan should be designed to avoid production of allergenic and non allergenic foods during the same shift. If this is impossible, non allergenic products should be produced first to avoid contamination from dust. Ingredients containing gluten should be identified by color-coded containers or stickers. Ingredients containing gluten must be added at the end of the shift after gluten free products are completed and removed. Rework containing gluten should be reused into the same products. Appropriate employee training and labeling for rework can also help to minimize the risk of cross contamination through human error. The possibility of contamination can easily be minimized by using dedicated equipment for the gluten free products. When it is impossible to have a separate building, the use of special barriers is necessary. The use of separate space and separate containers for all materials (as above) is recommended for gluten free production. In such conditions ventilation and dust flow must be well controlled. Dust flow in the plant has a potential to carry over allergens from separate spaces of facilities. [Guidance Note No. 24 Legislation on ‘Gluten-free' Foods and Avoidance of Cross-contamination during Manufacture of ‘Gluten-free' or ‘Very Low Gluten' Products Published by: Food Safety Authority of Ireland 2010, ISBN 1-904465-71-4]. Packing and labeling are also important elements in preventing cross contamination. Packing equipment may also be a source of contamination. The packaging machines and material should be checked for any allergens, e.g. foil coated with releasing agents derived from wheat flour. Appropriate labeling should be use to inform customers who are affected by coeliac disease. Correct labeling should reflect actual and real composition of the product. Labels must also fulfill legislative requirements. To facilitate recognition of gluten free products, labeling must be clear and readable. EU legislation regarding food labeling imposes an obligation to provide true and clear information about ingredients. Alerts to all allergenic ingredients, starch source (plant from witch starch originates) and gluten content are required. The manufacturer is obligated to ensure readability of the above information. Directive 2003/13/EC of 10 February 2003 posted in the Official Journal of the European Union requires that food manufacturers should place notification on labels of any of the fourteen groups of potential allergens responsible for more than 90% of allergic reactions if they have been used as food ingredients (including alcoholic drinks), regardless of the allergen content. The list of allergenic ingredients is constantly being updated. Also, the components derived from allergenic substances must be listed as potential allergens [ Czarniecka-Skubina E., Janicki A. 2009. Znakowani produktów żywnoÅ›ciowych. Informacje żywieniowe i zdrowotne. PrzemysÅ‚ Spożywczy, StyczeÅ„, 34-36; Commission Directive 2003/13/EC of 10 February 2003 amending Directive 96/5/EC on processed cereal-based foods and baby foods for infants and young children. Official Journal of the European Union L 41/33, 14.2.2003] Codex Alimentarius has proposed the introduction of the following descriptions in the vicinity of the product name. If the product comes from natural raw materials that do not contain gluten, it is described as "gluten free by nature," or "product may be used in gluten-free diet" [Hoffmann M., JÄ™drzejczyk H. 2007. Å»ywność bezglutenowa – legislacja i aspekty technologiczne jej produkcji. PostÄ™py Techniki Przetwórstwa Spożywczego, 1, 67-69]. Products low in gluten, are marked with the inscription: "very low gluten foods", "low gluten foods", or gluten-reduced foods [Wojtasik. A, Kunachowicz H., Daniewski W. 2008. Aktualne wymagania dla produktów bezglutenowych w Å›wietle ustaleÅ„ kodeksu żywnoÅ›ciowego. Bromat. Chem. Toksykol., XLI, 2008, 3, str. 229-233; Darewicz M., Jaszczak L.; „Oznakowanie produktów stosowanych w diecie osób chorych na celiakiÄ™", PrzeglÄ…d Piekarski i Cukierniczy, march, 2012.]. Training Employee awareness at all levels of production, beginning with plant growing to finished preparation of proper labels is necessary throughout the gluten free production chain. Everybody must be informed about the consequences of gluten consumption by coeliac patients. Staff who are employed from time to time must be also well trained. Implementation of control procedures and proper documentation will be very helpful in maintaining control. Documentation of the training of every new employee needs to be prepared and maintained. All working stuff and implemented methods must be supervised all the time [Guidance Note No. 24 Legislation on ‘Gluten-free' Foods and Avoidance of Cross-contamination during Manufacture of ‘Gluten-free' or ‘Very Low Gluten' Products Published by: Food Safety Authority of Ireland 2010, ISBN 1-904465-71-4]. By taking into account all aspects mentioned above and striving to make continuous improvements, manufactures are able to produce safe, high quality gluten free products. The human factor is one of the most important elements in this process because only human mistakes can lead to contamination and only good training and awareness at every stage of production stage can produce the best possible product. Implementation of quality management systems like HACCP or GMP assures customers of food quality and safety, while also allowing the producer to lower production costs related to potential human mistakes. However, nothing will really change the fact that all of the factors described above must be implemented in everyday production, ensuring that they are not simply ideas on the piece of paper. Implementation is the key. -
Can Production Cuts Stop Plummeting Wheat Prices?
Jefferson Adams posted an article in Additional Concerns
Celiac.com 10/24/2017 - Global wheat prices are plummeting in the wake of massive overstocks and anemic consumption. The problem is serious enough that Canada, the world's top producer of durum wheat, has cut its production nearly in half, to a six-year low. Even those drastic measures have had failed to raise prices, which are down about 30 percent from 2016. Worse still, experts are projecting a continuing decline in demand over the next year. Italy, Canada's second largest buyer of durum wheat in 2016, is planning to introduce rules in early 2018 that could further reduce imports. This comes at a time when consumers are buying less wheat products, as more and more people are adopting gluten-free, and low-carbohydrate diets. Italy is not the only problem for wheat growers, and durum is not the only variety to be hit by the reduction in demand. Weak demand overall will drive total global wheat stockpiles up to a record 263.4 million metric tons in 2017, according analysts surveyed by Bloomberg. Those predictions exceed estimates made by the U.S. Department of Agriculture, and the agency has already taken steps to revise its earlier estimate. According to Neil Townsend, a senior analyst at FarmLink in Winnipeg, Manitoba, Italy's plan is “just another nail in the coffin” to industry efforts to incrementally grow demand. After slowly bouncing back from the Atkins diet craze, the wheat industry is now “kind of getting gnawed away by the gluten thing. There's just no growth,” said Townsend.

Celiac.com 08/06/2009 - A study by a team of Spanish researchers puts the world on notice that gluten may trigger adverse reactions in both celiacs and non-celiacs alike. The research team was made up of E. Arranz, D. Bernardo, L. Fernandez-Salazar, J. A. Garrote and their colleague S. Riestra, all doctors based in Spain. According to the current medical wisdom, innate immunity to gluten plays a critical role in the development of celiac disease (celiac disease). This innate immune response is caused by a reaction to the ‘toxic’ gluten peptides that is mediated by interleukin (IL) 15, like the 19-mer through a DQ2-independent mechanism, and which causes epithelial stress and triggers the intraepithelial lymphocytes to turn into natural killer (NK)-like cells, which then causes enterocyte apoptosis and a compromised permeability of the cells lining of the gut…and, violà, celiac disease! It is by breaching this lining that immuno-dominant peptides, such as the 33-mer peptide, come into contact with the lamina propria, which triggers adaptive immunity. The innate specific response in celiac disease has been pretty well documented, but until recently, no one had described any differential factors between people with celiac disease and those without. Since the toxic 19-mer triggers its damaging effects through a DQ2-independent mechanism, doctors wondered whether the innate immune response was common in both people with and without celiac disease, and whether the adaptive response is emblematic only of susceptible people with celiac disease. A team of researchers recently set out to determine just that, beginning with biopsies from at least three patients with celiac disease who were observing a gluten-free diet and three patients who are free of celiac disease. The research team consisted of D. Bernardo, L. Fernandez-Salazar, J. A. Garrote and their colleague S. Riestra, all based in Spain. The team applied crude gliadin, the gliadin synthetic 19-mer and deaminated 33-mer peptides to the biopsy tissue after discarding the presence of lipopolysaccharide. They did this at concentrations of 100 mg/ml for 3 hours to mimic what are considered the standard timing and concentration in the digestive tract after a routine meal. The research team then washed the specimens and cultured them for 21 hours in new clean culture medium to assess whether an innate stimulus is reflected by an adaptive response. Here’s some technical jargon: Each sample cultured in basal medium served as an internal control. Innate immune mediators IL15 and nitrites were measured by western blot in the biopsy protein extract along with a Griess reagent system in the 3 h supernatants respectively. mRNA levels of adaptive immunity mediators like signal transducers and activators of transcription (STAT) 1, STAT3, tumour necrosis factor a, interferon (IFN) c, IL23 (p19), IL27 (p28) and IL12 (p35) were determined by real-time polymerase chain reaction using b actine levels as house-keeping. Compared with the basal culture, all of the patients were challenged with the gliadin solution, and all of the patients, both those with and those without celiac disease on a gluten free diet, showed IL15 production, which indicates an immune reaction is taking place. More importantly, the IL15-mediated response in patients without celiac disease was triggered, in three of six cases, by the same toxic 19-mer gliadin peptide and, in five of six cases, by the 33-mer gliadin peptide as in those with celiac disease. Significantly, none of the basal cultures showed this result, though the ‘‘non-toxic’’ immuno-dominant 33-mer did induce an innate response that was un-foreseen. Interestingly, one patient with celiac disease and on a gluten-free diet, and three patients without celiac disease, who were also on gluten-free diets, all showed the IL15 response, which was confirmed by western blot analysis. This discounts an intracellular and non-biologically active IL15 response in patients without celiac disease. The gliadin-challenged patients with celiac disease who were on a GFD, showed increased nitrite levels, which those without celiac disease did not show. Following the biopsy mRNA isolation, only patients with celiac disease showed modifications to what are called adaptive mediators (STAT1, STAT3, IFNc). The basal samples of those celiac patients on a gluten-free diet showed IFNc mRNA levels that were 80 times higher than basal samples of those without celiac disease (p value 0.002), along with a slightly higher production of nitrites (p value 0.052). This appears to be the first time that researchers have described an IL15-mediated innate response to gliadin and gliadin peptides in people without celiac disease, as well as the first time they have described an IL15-mediated innate response to the ‘non-toxic’ deaminated immuno-dominant 33-mer peptide. What this all means is that, for the first time, scientists have documented harmful effects of gluten on people without celiac disease. This hypothesis seems to be born out by the fact that all individuals who took place in the study, both those with and those without celiac disease, showed an innate immune response to gluten, though only those with celiac disease showed an adaptive immune response to gluten. Clearly, before doctors can draw any hard and fast conclusions, they will need to do more studies on larger groups. The research team also suggests that people with celiac disease have a lower threshold for triggering an adaptive TH1 response than do non-celiacs, and that people with celiac disease need to be DQ2 positive. The reason for the differences in threshold levels between celiacs and non-celiacs might be tied to the fact that celiac patients show higher basal levels of immune mediators, such as IFNc mRNA, compared to those without celiac disease. That’s one possibility. The difference in threshold levels might also have to do with some kind of defect in permeability of the gut membrane in those with celiac disease, or even a greater IL15-sensitivity response under equal stimulus, which might be mediated by a higher density of IL15 receptor in patients with celiac disease.

The following was a post from Merete Askim regarding the avoidance of the contamination of foods during the manufacturing process. If you have any questions regarding it, direct them to him at: Merete.Askim@INF.HIST.NO. My name is Merete Askim, and I am a College Lecturer at the Department of Food Science, Soer-Tronedelag College, Trondheim, Norway. In my teaching in nutrition and food chemistry, I am very interested in food allergy and intolerance. My students get jobs as food technologists, so it is important for them to be aware of food allergy and intolerance. I have invented a new concept which I call ALLERGY-HYGIENICS. This combines both the aspects of avoiding contamination by: Harmful Bacteria Ingredients Not Meant to be Part of the Food in Question A traditional concept in industrial food production is called HACCP (Hazard Analysis Critical Points), which is concerned primarily with bacterial contamination. My new concept ALLERGY-HYGIENIC improves upon HACCP, by adding the concept of consideration of allergic and intolerant ingredients, either directly through insufficient consideration of the impact of an ingredient on the population, or inadvertently through contamination by ingredients not meant to be part of the food in question. We teach the students to start the analysis of food production with the least complex product, and end with the most complex, to have knowledge of every ingredient, down to the smallest, including the food-additives. For example, some firms use vacuum tubes to deliver ingredients from storage facilities to their production machinery. If a gluten free product is being made, and the tube used to deliver rice flour was previously used to deliver wheat flour, there is likely cross-contamination which cannot be removed by simply cleaning the final production machinery. The tube itself would have to be cleaned out, or the facility would have to be designed so that gluten free flours are never transported in tubes which at other times contain gluten. Another example is when a dairy produces both "strawberry-yogurt" and "raspberry -yogurt" on the same day, the ALLERGY-HYGIENIC concept is to avoid any strawberry contamination in the raspberry product, or vice versa. Our goal is that all products will eventually have ALLERGY-HYGIENIC qualities! But we know this takes time and can be expensive in some occasions. It is a new concept in the traditional way of hygienic thinking. Even with ALLERGY-HYGIENICS, we can not guarantee no contamination, but we are attentive, and take our precautions. At our Department of Food Science, Trondheim, Norway, want this new concept ALLERGY-HYGIENIC to catch-on all over the world, and become common knowledge. So please tell others, and if you dont mind, remember that it was created here. When you are in contact with the food-industry, you might ask them: Is your production in accordance with ALLERGY-HYGIENIC principles? Have you taken ALLERGY-HYGIENIC considerations in your production? If you find this concept useful, please let me know by private email. I would also be interested in your experiences as Celiacs with locating cross-contamination in foods. By cataloging your real-life experiences in the field, I can help my students and their companies determine likely problematic areas in food production.
