My battery's about to run out stendra rx â¢ Beware of allergens! Alcohol labeling laws still allow major leeway in what's required. The disclosure of major allergens is not required for alcohol labels, as it is for other foods and beverages. Currently, only the disclosure of FD&C Yellow No. 5, saccharin, sulfites, aspartame (in malt beverages only) and color additives (such as cochineal extract and carmine) are required. Optional labeling guidelines for major allergens â such as tree nuts, peanuts, shellfish, milk, eggs, gluten and soy â are available, but not mandatory. This is troublesome for the estimated 4 percent of Americans with food allergies. Uneducated or new drinkers can easily be mistaken.
