Allergen's labeling of food products: regulatory practices in Morocco

PurposeAllergenic substances cause food allergy, which represents a major health issue in most countries. This underlines the importance of considering the products' labeling as well as applying related regulatory practices. The objective of this study was to assess the labeling practices of allergens in food products in Morocco.Design/methodology/approachThis cross-sectional survey was conducted on 156 food products collected from four supermarkets in a Moroccan megacity. The data related to the allergen substances (allergen declared, emphasis characters, precautionary allergen labeling) were collected from labels of food products.FindingsThe number of foods included in this research was 156, of which 7 (4.5%) did not mention the allergy alert. The analysis of the allergy alert in the others sample (149) showed 266 nonconformities, noticed in 112 (71.8%) products. The labeling emphasis characters were observed in 33.3% of products, and only 13.5% mentioned “contains allergen” as a mandatory statement to declare the presence of allergens. Allergic alerts found in places concealed, removable by the opening of the seal or difficult to see were observed in 28.9%. The use of a precautionary allergen labeling statement was noticed in 40.4% of products.Originality/valueMoroccan regulations on food allergens are demanding like those of the European Union and more demanding than those of most African countries. However, the application of this regulation remains unsatisfactory and 266 non-conformities were found in 112 (71.8%) products. The absence of emphasis characters and the declaration in inappropriate places represent the most observed non-conformities. Therefore, Moroccan manufacturers must strictly adhere to regulations to avoid exposure of predisposed consumers to potentially threatening allergenic substances.

Glycation end products and technological aspects of reducing immunogenicity of specialized food products for nutrition of athletes

Food allergy, which affects about 8% of children and 5% of adults in the world, is one of the major global health problems, and allergen control is an important aspect of food safety. According to the FALCPA (Food Allergen Labeling and Consumer Protection Act of 2004 FDA), more than 160 foods can cause allergic reactions, with eight of them responsible for 90% of all food allergies in the United States, including milk, eggs, wheat, peanuts, soybeans, tree nuts, crustaceans and fish, also known as the Big 8. Most foods that are sources of obligate allergens are heat treated before consumption, which can trigger the Maillard reaction, which produces glycation end products. Symptoms of food sensitization are known to significantly affect the quality of life, gut microbial diversity and adaptation potential. In particular, in athletes, this can be expressed in a decrease in the effectiveness of the training process, which leads to poor endurance and athletic performance. In this regard, it seems relevant to study the effect of the Maillard reaction and AGEs on the immunogenicity of proteins and the possible relationship between these compounds and food allergy, as well as to develop measures to prevent the adverse effect of allergens on the body of a professional athlete and any other consumer.

Peanut and hazelnut occurrence as allergens in foodstuffs with precautionary allergen labeling in Canada

Precautionary allergen labeling (PAL) is widely used by food industries. Occurrence studies revealed that few analyzed products contained the allergen(s) present in the statement, but little is known in Canada. To improve manufacturing practices and better manage allergen cross-contamination, occurrence data is needed to determine the exposure of allergic individuals eating those products. Samples were analyzed for peanuts (n = 871) and hazelnuts (n = 863) using ELISA methods. Within samples analyzed for peanuts, 72% had a PAL (n = 628), 1% had peanuts as a minor ingredient (n = 9) and 27% were claimed “peanut-free” (n = 234). Most hazelnut samples had a PAL for tree nuts/hazelnuts (94%; n = 807) with 6% claimed “nut-free” (n = 56). Peanuts and hazelnuts were found in 4% (0.6–28.1 ppm) and 9% (0.4–2167 ppm) of all samples, respectively. Chocolates were mostly impacted; they should be treated apart from other foods and used in risk assessments scenarios to improve manufacturing practices, reducing unnecessary PAL use.
