Why is "Adulterated food in the United States" trending?

Wikipedia Overview

Food adulteration is a legal offense in the United States. When a food product fails to meet the legal standards outlined in the Federal Food, Drug, and Cosmetic Act of 1938, it is legally considered to be adulterated food. One form of adulteration is the addition of another substance to a food item in order to increase the quantity of the food item in raw form or prepared form, which results in the loss of the actual quality of the food item. These substances may be either available food items or non-food items, and are commonly referred to as adulterants. Among meat products some common adulterants are water or ice, carcasses, or carcasses of animals other than the animal meant to be consumed. In the case of seafood, adulteration may refer to species substitution (mislabeling), which replaces the species identified on the product label with another species, or undisclosed processing methods, in which treatments such as additives, excessive glazing, or short-weighting are not disclosed to the consumer. While adulteration commonly refers to the unapproved use of bulking agents or additives, the sale of poisonous, unsanitary, or improperly stored food is also considered adulteration under US law.
