Prevention Strategies: Key Rules for Safe Eating

1. Master Street Food Selection

Street food is central to Mexico City’s culture, but not all vendors meet hygiene standards. Follow these guidelines:

  • Choose busy stalls: Long lines indicate fresh, high-turnover food and local approval.
  • Observe food handling: Avoid stalls where the same person handles raw meat and cooked food or touches money and food without gloves.
  • Check for hygiene: Prioritize vendors with visible hand sanitizer and separate staff for cooking and cash handling.
  • Opt for piping-hot dishes: Heat kills bacteria. Avoid lukewarm items left exposed to open air.

Handle Fruits and Vegetables Carefully

Raw produce is a common source of contamination. To minimize risk:

  • Stick to peelable fruits: Bananas, mangoes, and oranges are safer than pre-cut options.
  • Avoid raw salads and salsas: Leafy greens and finely chopped ingredients are harder to clean thoroughly.
  • Use lime juice: Douse raw vegetables or street food with fresh lime, which has natural antibacterial properties.

What to Do If You Get Sick

Immediate Home Treatment:

  1. Hydrate aggressively: Combat dehydration with bottled water, coconut water, or electrolyte solutions like Electrolit.
  2. Stick to bland foods: Try plain rice, toast, or bananas once vomiting subsides.
  3. Monitor symptoms: Track fever, fluid intake, and bathroom frequency to determine if urgent care food poisoning treatment is needed.

Self-Care with Over-the-Counter Medicine:

  • For nausea: Pepto-Bismol (available in Mexican pharmacies)
