Here's the best blog post I found about avoiding sickness when in Mexico. It's not Columbia but seems relevant.

Here's all the **** without the fluffy blog part.
Street food. Bypass food stalls with the following red flags:
- The same person handles raw meat and fresh veggies / tortillas.
- The same person handles food and money.
- There is nowhere for the cook / vendor to wash their hands.
- Food (raw meat, in particular) sits in the open air / sun for extended periods.
Preventative measures:
- Wash your hands with soap and water. Carry hand sanitizer with you.
- Begin taking probiotic pills one week before your trip and continue during. These are recommended: Jarrow Formulas Saccharomyces Boulardii + MOS - 5 Billion CFU.
- Pack anti-diarrheal meds (Pepto, Imodium) and talk to your doctor about a prescribed antibiotic to have on hand in case of serious illness.
- Stay hydrated. A pinch of salt or squeeze of lime can help you. Sip throughout the day.
- Be mindful about overindulging with food and booze - the food is very rich.
DO NOT DRINK THE WATER
- Fine dining establishments that cater to tourists typically use bottled water in ice cubes and drinks but VERIFY THIS with your server.
- Be especially cautious with fresh juices, especially street food juice stalls.
- When buying bottled water, always confirm the bottle cap is properly sealed and twist it off yourself. Do NOT let the vendor twist it off for you.
- Don't swallow the tap water used to brush your teeth - best to use bottled water for that, too.
- Don't open your mouth in the shower or you'll probably die.
- If you care about plastic / the environment, consider a reusable bottle that filters out crap: GRAYL water purifying bottles.
Raw Fruits & Veggies
- Be careful here as raw fruits and veggies may not have been washed with purified water (or washed at all).
- When in doubt, douse your food with fresh lime juice as it helps to kill bacteria.
- To be extra safe, stick to fruit that can be peeled, such as bananas and mangos.
Spicy Food
- Green sauces are often the hottest. Clarify that it's not avocado sauce beforehand.
- Sauces are often made with tap water, especially on street carts. So avoid if you can't confirm that it was prepared with purified water.
Eating Meat
- Opt for medium-well done, even in nice restaurants, and avoid eating it rare.
- Seafood is particularly dangerous and should be avoided at street food stalls and restaurants without proper refrigeration.
