The Madrid Open has turned into a battle against an invisible adversary as a wave of gastrointestinal illness has swept through the tournament, sidelining several high‑profile competitors and raising concerns about food safety on the grounds. While the exact source of the outbreak remains unconfirmed, many players and officials suspect a contaminated dish—most notably shrimp tacos—may be at the heart of the problem.
The issue first came to light when rising American star Coco Gauff, who had just secured a dramatic third‑set tiebreak victory over Sorana Cirstea in the round of 32, began to feel unwell during her subsequent match against Linda Noskova. Gauff, who ultimately fell to Noskova in the round of 16, was visibly struggling in the earlier encounter; she called for the team's physiotherapist midway through the second set of her 4‑6, 7‑5, 6‑1 win over Cirstea. Moments later she was seen vomiting on the court, prompting medical staff to check her blood pressure and monitor her condition closely.
Gauff’s symptoms were not an isolated incident. Over the past few days, the tournament has seen a string of withdrawals and retirements that point to a common underlying cause.
Six‑time Grand Slam champion Iga Swiatek pulled out of her match against Ann Li, describing herself as having "zero stability and zero energy" before she was forced to retire. Similarly, veteran Marin Cilic was forced to forfeit his scheduled match against Joao Fonseca, citing food poisoning as the reason for his inability to compete. Madison Keys also withdrew, adding to the growing list of top‑ranked athletes affected by the mysterious bug. Rumors among the players have coalesced around a single suspect: shrimp tacos served at one of the on‑site food stalls.
Although tournament officials have not officially confirmed the source, the timing of the illnesses and the common dietary exposure have led many to suspect that a batch of undercooked or improperly stored seafood may have been the trigger. The speculation has been amplified by social media posts and informal conversations in the players' lounge, where athletes have been seen jokingly warning each other to avoid the popular Mexican‑style snack. In the midst of the health scare, world number one Aryna Sabalenka offered a pragmatic response after her fourth‑round triumph over Naomi Osaka. Sabalenka, who has been a strong contender for the title, explained that she has adopted a very plain and controlled diet for the duration of the tournament—primarily chicken breast, rice, and salad—in an effort to minimize any risk of infection.
"I stick to the same food, same meal that I've been having since the very beginning of the tournament," she said, adding a light‑hearted comment about avoiding the suspect tacos. Her approach appeared to pay off, as she rallied from a set and a break down to defeat Osaka 6‑7 (1‑7), 6‑3, 6‑2, keeping her title defence hopes alive. Medical staff on site have been working around the clock to assess and treat affected players. Routine checks include blood pressure monitoring, hydration therapy, and, where appropriate, anti‑nausea medication.
The tournament’s medical director has urged players to stay hydrated, get plenty of rest, and report any symptoms immediately. In addition, the organizers have temporarily suspended service at the implicated food stall while a thorough inspection is carried out. The situation has also sparked a broader discussion about food safety protocols at major sporting events. Experts note that large gatherings, especially those involving athletes who are under intense physical stress, require stringent hygiene standards for all food vendors.
They recommend regular temperature checks, proper storage of perishable items, and clear labeling of ingredients to prevent cross‑contamination. The Madrid Open’s organizers have pledged to review their vendor vetting processes and to implement additional safeguards to avoid a repeat of this episode. For fans watching from home, the tournament continues to deliver high‑quality tennis despite the setbacks.

As the competition progresses, players like Sabalenka, who have adhered to a disciplined diet, appear to be navigating the health scare more successfully than those who may have been exposed to the tainted tacos. The next few days will be crucial in determining whether the outbreak can be contained and whether the remaining field can compete at full strength.
Regardless of the outcome, the Madrid Open has underscored the importance of vigilance, both on the court and in the cafeteria, reminding everyone that sometimes the toughest opponent is invisible and comes on a plate.
