Simulated use of thresholds for precautionary allergen labeling: Impact on prevalence and risk.

Heterogeneity and overuse of precautionary allergen labelling (PAL) in prepackaged foods have eroded its risk communication efficacy. Experts recommend applying PAL based on allergen concentration thresholds, but adoption remains limited. The aim of this study was to quantitatively assess the potential impact of this approach using Monte Carlo risk simulations.

Lead exposure from honey: meta-analysis and risk assessment for the Arab region.

The Codex Alimentarius Commission has adopted a maximum level for lead in honey (0.1 mg/kg). Despite representing a population of more than half a billion, exposure and risk assessments for lead specific to the Arab region are lacking.

"Vegan" and "plant-based" claims: risk implications for milk- and egg-allergic consumers in Canada.

The market share of foods carrying labels suggesting absence of animal ingredients has significantly increased in recent years. The purpose of this study was to document the purchasing behaviour of egg- or milk-allergic consumers vis-à-vis food marketed as "vegan" and "plant-based", and to evaluate the associated allergenic risk. A survey was conducted among egg- and milk-allergic consumers and revealed that 86% (margin of error 5.

Risk assessment supporting the establishment of a maximum residue limit for ractopamine in beef liver, applicable in the Arab Republic of Egypt.

In 2012, the Codex Alimentarius Commission adopted maximum residue limits (MRLs) for ractopamine in pig and cattle tissues. Egypt, a country that records a high consumption of beef liver, conducted a health risk assessment to estimate the risks associated with the adoption of Codex MRLs and the possible adoption of alternative values that may offer higher protection. Ractopamine was characterized based on previous assessments performed by international regulatory agencies, and an acceptable daily intake was set at 1 µg/kg bw for both chronic and acute ractopamine exposure.

Allergen management under a voluntary PAL regulatory framework - A survey of Canadian food processors.

Canadian regulations require food business operators (FBOs) to implement preventive controls to manage allergens and ensure their accurate declaration. However, the use of precautionary allergen labelling (PAL) is voluntary and competent authorities provide limited guidance on its use. The objective of this study was to present an overview of Canadian FBOs' current allergen management practices, including the mechanisms used to evaluate the need for PAL in finished products, and to investigate potential areas for improvement.

Spent fowl as a source of unintentional egg proteins exposure in Canadian food products.

The occurrence of egg proteins in products containing spent fowl manufactured under current practices was studied to assess the risk these food products may pose to egg-allergic consumers and to determine if Precautionary Allergen Labelling (PAL) was recommended. Spent fowl slaughtering and processing operations in 2 Canadian facilities were observed. Raw hen pieces (n = 134), coming from 2 facilities, and intermediate and processed products containing spent fowl (n = 57), coming from one facility, were analyzed using ELISA.

Validation of the RIDASCREEN® Peanut for Determination of Peanut Protein in Cookies, Milk Chocolate, Ice Cream, Trail Mix, Puffed Rice Cereals, and Granola Bar: AOAC Performance Tested MethodSM 112102.

Background: Regulations in many countries worldwide prescribe that peanut must be listed on food labels as a cause of food allergies. Re-evaluated voluntary incidental trace allergen labelling (VITAL) values for peanut revealed the eliciting dose (ED01) value-at which 99% of all peanut-allergic individuals will not react-is 0.2 mg peanut protein.

Evaluation of the discriminatory potential of antibodies created from synthetic peptides derived from wheat, barley, rye and oat gluten.

Celiac disease (CD) is triggered by ingestion of gluten-containing cereals such as wheat, barley, rye and in some cases oat. The only way for affected individuals to avoid symptoms of this condition is to adopt a gluten-free diet. Thus, gluten-free foodstuffs need to be monitored in order to ensure their innocuity.

Sesame as an allergen in Lebanese food products: Occurrence, consumption and quantitative risk assessment.

Despite the intensive use of sesame in the Middle Eastern diet, studies on this allergen in this region are lacking. A survey on the occurrence of sesame in Lebanese food products that did not contain this allergen as an ingredient, a food consumption survey conducted in Beirut schools, and the most recent sesame eliciting dose estimates were used to build a probabilistic risk assessment model providing estimates of sesame-induced allergic reactions per eating occasion and per week in Lebanese children and adolescents. Of 1270 food samples analysed, 34% contained sesame proteins (0.

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.

Probabilistic risk assessment for milk in dark chocolate, cookies and other baked goods with PAL sold in Canada.

The risk of having an allergic reaction in milk-allergic individuals consuming products with precautionary allergen labelling (PAL) for milk has been rarely studied in products such as dark chocolate, cookies, and other baked goods. A probabilistic risk assessment model was developed to estimate potential risks. Milk occurrence and contamination levels were reported in a previous article from our group.

Occurrence and risk assessment of sesame as an allergen in selected Middle Eastern foods available in Montreal, Canada.

Sesame allergy is a public health problem in many countries around the world. The purpose of this study is to determine the occurrence of sesame allergen in unlabelled or labelled free-sesame Middle Eastern foods with or without Precautionary Allergen Labelling (PAL) 'may contain' and estimate the risk incurred by the Canadian population allergic to sesame with a focus on products purchased in Middle Eastern grocery stores and bakeries in Montreal, Canada. A total of 571 samples were analysed to determine the level of sesame protein.

Summary of the AOAC-Sponsored Workshop Series Related to the Global Understanding of Food Fraud (GUFF): Mobilization of Resources for Food Authenticity Assurance and Food Fraud Prevention and Mitigation.

Background: Reports of incidents associated with the misrepresentation of food products as well as the adulteration of their composition leading, at times, to significant public health impacts are being recorded.

Objective: This paper aims at summarizing the outputs of three workshops dedicated to the theme "Global Understanding of Food Fraud" (GUFF), held in Quebec City in Canada (April 2017), Beijing in the People's Republic of China (October 2017) and Dubai in the United Arab Emirates (October 2018).

Occurrence of milk and egg allergens in foodstuffs in Canada.

Food allergies are life-threatening conditions that allergic individuals can avoid by consulting the food labels before consuming. Precautionary allergen labelling (or PAL), to warn against possible allergen cross-contamination, is widely used by food industries, reducing the food choices for allergic individuals. In Canada, there is limited information on the actual occurrence of allergens in products with a PAL related to the given allergen.
