Risk characterisation of milk protein contamination in milk-alternative ice cream products sold as frozen desserts in the United States.

Milk protein is recognised as one of the eight most common food allergens in the United States, and one of the most common causes of fatal or near-fatal food-induced anaphylactic reactions globally. Undeclared allergens in food products are the leading cause of the U.S. Food and Drug Administration (FDA) requests for food recalls, with undeclared milk protein as the most frequently cited allergen. The purpose of this study was to evaluate the prevalence of milk protein contamination in milk-alternative ice cream products sold as frozen dessert in the U.S. and labelled as 'non-dairy', 'dairy-free', and/or 'vegan', and to characterise the potential risk for allergic individuals consuming these products. Thirty-two unique milk-alternative frozen dessert products, including flavours with and without inclusions, from 16 different brands, were tested for the presence of milk proteins using enzyme-linked immunosorbent assay. Milk protein was detected in three of the tested products: two contained solid inclusions, and one did not have inclusions. One of the three products with detectable milk protein had an advisory statement indicating the product was made in a facility that processed milk. Although no consensus exists as to the minimal dose of milk protein necessary to elicit an adverse effect in a milk-sensitised individual, the milk protein quantities in one serving of each of the three products exceeded some of the published thresholds. These results suggest that one serving of certain milk-alternative frozen dessert products could potentially elicit an allergic response in highly sensitive individuals.

A comparative evaluation of dietary exposure to glyphosate resulting from recommended U.S. diets.

Since its commercial introduction in 1974, national and international regulatory agencies have consistently reported no human health concerns associated with the herbicide glyphosate when used according to label directions. However, in 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as a probable human carcinogen. Despite IARC being the sole outlier in its conclusion, dietary exposure to glyphosate remains a health concern to some members of the public. While glyphosate residues have been detected in foods, it is unclear whether a specific eating pattern substantially contributes to glyphosate exposure. Therefore, dietary glyphosate intake was determined for three eating patterns recommended in the U.S. The 95th percentile of glyphosate ingestion at 2,000 calories/day for adults for the U.S.-Style, Mediterranean-Style, and Vegetarian eating patterns ranged from 38 to 960, 39 to 1100, and 39 to 880 µg/day, respectively. No significant differences were observed in glyphosate intake between the dietary styles, and the 95th percentile glyphosate intakes were well below the current U.S. EPA chronic oral reference dose (RfD) of 0.1 mg/kg/day. Our data demonstrate that ingestion of certain high residue foods, particularly grains and legumes, is a driver of total dietary glyphosate body burden regardless of dietary style.
