Salmonella Outbreak Affects 90 Students & Teachers at Madrid School-What Parents Need to Know

A salmonella outbreak declared on Tuesday, June 16, has affected approximately 90 students and staff at the Colegio Estudio Conde Orgaz in Madrid’s Hortaleza district, according to the Madrid Health Council. No hospitalizations have been reported, the council confirmed. The incident was first identified after students and teachers began exhibiting gastrointestinal symptoms, prompting health officials to initiate an investigation.

Health authorities contacted local pediatricians to request stool cultures for children presenting symptoms, the council said. Results from the tests, conducted on Friday, confirmed salmonella infections among the affected individuals. A kitchen inspection was carried out, and food samples from June 15 were collected for analysis, according to the Health Council. A informational notice was also sent to the school’s administration to distribute to parents, following standard protocol.

The Health Council emphasized that the outbreak remains contained, with no further cases reported beyond the initial 90. “All necessary measures have been implemented to ensure the safety of the school community,” a spokesperson stated. The institution has not yet released a public statement, but the council noted that the situation is under review.

Salmonella, a common foodborne illness, is caused by the bacterium Salmonella and spreads through contaminated food or water. Symptoms include fever, abdominal pain, diarrhea, nausea, vomiting, and headaches, typically appearing six to 72 hours after exposure. The illness usually lasts two to seven days, according to the Spanish Agency for Food Safety and Nutrition (AESAN).

Transmission occurs via undercooked poultry, eggs, or dairy products, as well as contaminated water or raw fruits and vegetables. The agency highlighted that salmonella is one of the most frequently reported foodborne diseases in the European Union and other regions.

The Madrid Health Council’s response aligns with standard procedures for such outbreaks, including tracing potential contamination sources and advising affected individuals to seek medical care if symptoms persist. “Preventive measures are critical to avoid further cases,” the council said.

No specific food item has been identified as the source of the outbreak, but the inspection of the school’s kitchen and food samples from June 15 is ongoing. Health officials are also monitoring for secondary cases among individuals who may have come into contact with infected students or staff.

The school, a private institution, serves approximately 500 students. Parents were informed of the outbreak via the notice sent to the administration, though details about the school’s internal protocols remain unclear. Local health authorities have not indicated whether the school will close temporarily.

Salmonella outbreaks in educational settings are rare but not unprecedented. In 2022, a similar incident in Barcelona affected over 100 students after contaminated chicken was served at a school cafeteria. That outbreak led to updated food safety guidelines for public institutions.

The Madrid Health Council reiterated its commitment to transparency, stating that updates will be provided as new information becomes available. Residents are advised to report any symptoms of foodborne illness to local health services.

For now, the focus remains on preventing further spread and ensuring the affected individuals receive appropriate care. “The health and well-being of the community are our priority,” the council said.

The Spanish Agency for Food Safety and Nutrition (AESAN) provides guidelines for preventing salmonella infections, including thorough cooking of food, proper handwashing, and avoiding cross-contamination. Individuals experiencing symptoms are encouraged to consult healthcare providers and avoid preparing food for others until cleared.

Health officials continue to investigate the source of the outbreak, with no indication of a broader public health risk. The case underscores the importance of vigilance in food safety, particularly in environments where large groups of people consume meals together.

Residents in Madrid are advised to stay informed through official channels and follow health guidelines to minimize the risk of foodborne illness. The Madrid Health Council has not yet commented on the long-term implications of the outbreak for the school or local community.
