The Attorney General's Office of Puebla reported that one of the six minors hospitalized for suspected food poisoning in Huauchinango tested positive for fentanyl in a toxicology test. However, this result is attributed to the medications administered during their medical care. The case has prompted the state’s prosecutors to open an investigation for negligence after the children were admitted to the General Hospital of Huauchinango, apparently due to the consumption of contaminated tamales.

Following the incident, the United States Ambassador to Mexico, Ronald Johnson, expressed his sorrow over the poisoning of the children, emphasizing that fentanyl does not discriminate between individuals from Mexico or the United States. This statement underscores the grim reality of fentanyl's impact across borders, as concerns grow about drug safety and the potential for similar occurrences in both countries.

This incident raises critical questions about food safety standards in Puebla, particularly regarding the sale and distribution of food items like tamales. The investigation into potential negligence aims to determine accountability and prevent future incidents, highlighting the prevalent issue of foodborne illnesses and the importance of strict regulations in food service industries.
