Bars in downtown Leon, Guanajuato, allegedly replace original alcoholic beverages with adulterated versions after midnight without the knowledge of their customers [1, 2].
This practice poses a significant public health risk because adulterated alcohol can contain toxic chemicals. When patrons are already intoxicated, they are less likely to notice changes in taste or quality, making them vulnerable to poisoning.
A former employee of a bar in the city center provided the testimony regarding these operations [1, 2]. According to the source, the substitution occurs during late-night hours to ensure that customers do not perceive the difference between the authentic products and the fake alternatives [1, 2].
The scale of the alleged deception is wide. The former employee said that thousands of consumers have been potentially exposed to these adulterated drinks [1].
Local authorities have not yet issued a formal response to these specific allegations. The reports highlight a pattern of behavior in the downtown area where the timing of the switch is designed to exploit the impaired judgment of the clientele [1, 2].
Because the drinks are served in a high-traffic nightlife district, the potential for widespread exposure remains a primary concern for residents and visitors in Leon [1, 2].

The allegation suggests a systemic attempt to increase profit margins by reducing ingredient costs through adulteration. Because the practice is timed to coincide with peak intoxication, it bypasses the natural sensory warnings of the consumer, shifting the burden of safety entirely onto regulatory inspections which may be infrequent during late-night hours.
