Food Safety

The lady in tianguis cuts off a chunk of cheese and thrusts it at you impaled on the point of a knife...

The vendor wants you to sample a chunk of melon on a plate

How long has that jar of mayonnaise been sitting on the taco preparation shelf?

The biggest myth circulating among gringo turistas is that heavy doses of fresh limon juice kills bacteria...
The fact is much of the outbreak of cholera in Mexico City a decade or so ago was spread by wandering ceviche vendors selling pickled fish doused with lots of limon. Even pure limon juice cannot kill many forms of bacteria. Virus yes -- bacteria no. Use common sense.

Watermelon and cantaloupe can osmosis bacteria bacteria right from the ground it's growing in. When I grow cantaloupe it's after cow manure has been in the ground for six months. And no, this is not a myth.

If you find a cracked egg, careful inspection may reveal a perfectly sealed product within an unbroken sack. Crack the suspicious egg into a separate bowl. Discard of the yolk is broken or the white does not look right. Eggs do not to be refrigerated if kept out of sunlight and at temperatures less than 80F. If eggs spoiled that rapidly chickens would have died out millions of years ago.

Super sterilized un-refrigerated box milk lasts longer even after being opened. Whereas fresh refrigerated milk turns sour a few days after being opened, box milk has remained perfect in my refrigerator for longer than a week.

Many people do not understand that properly refrigerated food means food kept at 35F to 38F and this includes food store on door shelves. I am convinced many RV'ers ignore this and sicken themselves because they have no idea of how chilled their refrigerator is.

People are paranoid about sterilizing fresh vegetables in Mexico. Most USA vegetables sold in the winter have their origin in Mexico. It takes a full half hour immersion in weak iodine to sterilize a head of lettuce but wait, read the wrapper, lettuce and celery comes from the US!

I have had notoriously bad luck with shrimp especially shrimp ceviche and shrimp cocktails. The safest way to cook shrimp is to boil it which causes tears to flow because I love shrimp sauteed in butter and garlic.

Shopping in an open market meat shop means dealing with flies, the sight of which makes my skin crawl. if you buy market meat, at home soak it raw like you do vegetables in sterilizing water and drops.

I never buy ranch cheese from an unknown wandering vendor. Queso blanco is uncooked, and unsterilized. It came from an unknown rancho. Always rely on advice from a local before buying soft white ranch cheese. Other cheeses are cooked. Hard cheese is legal to bring home.

Hopefully this thread will see extensive discussion and additions :)
  • I was going to stay out of this thread, but as qtla9111 said, "I don't care for these threads as it spreads some old myths as well as misinformation about Mexico and scares off possible Mexophiles."

    Like Mexicowanderer, navagator, and qtla9111 we live in Mexico full time. We have a decent feel for what food is safe and what isn't, at least in general. We all have opinions on it, some strong like mine.

    We believe that most tourists who get the touristas are suffering from too much sun, too much tequila, too much hot salsa and too much fun. If that isn't it, drink a lot of fluids, use Pepto Bismol and/or Imodium.

    We don't have a Costco here, but do have a Sam's Club. We are members for one thing: Dog food. They have a quality dog food that our dogs do well on, our other choice would be imports. Considering how much our two weimaraners eat, the membership is worth it. We have two supermarkets, and shop at one weekly when the maid and gardener are here. That is basically for the stuff we don't want to have to hunt for-pasta, toilet paper, basics. Everything else pretty much comes from the mercado, beach or street corners.

    I'll go down Mexicowanderer's list. If you watch those vendors with fruits that offer you a sample on the end of a knife, they aren't handling the edible portions with their bare hands, because of cleanliness. Watch the taco vendors-if they handle food they don't handle money-or if they do, they put their hand in a plastic bag to prevent contact with the dirty money. Watch McDonalds. They handle food and money.


    That mayonnaise? Commercial mayonnaise is shelf stable, even after opening. Refrigeration is only suggested to maintain quality.

    Eggs in Mexico, and in most of the world except the US are unwashed which makes them shelf stable for a long time. Cracked? Really want to take a chance in any country? Occasionally I'll hard boil cracked ones for the dogs if there has been an egg accident.

    RV refrigerators aren't the most efficient, so hopefully people keep a thermometer in them and check it. We found that adding a small computer fan to the outside coils and one of the battery operated fans to the inside makes a HUGE difference.

    Here's the biggie, and it's true. Unless there is visible dirt, we don't wash our veggies and lettuce. Honest. US or Mexico, nope. Cook it and eat it, use the lettuces, cilantro, onions, and other great goodies we buy from the ladies behind the market. Our personal choice.

    Shrimp is one of our favorites. In Mazatlan, we always bought from the shrimp ladies on their street, they are in washtubs with water and ice. Yesterday we bought a kilo of locally caught shrimp from our fish guy who sells on a corner with an ice chest, steamed them and had a fabulous lunch. Obviously, look and smell what you are buying. We have seen very nasty shrimp in major chain stores in California, but not here.

    The meat market!!! We love buying meat that smells like meat, not a plastic package. We don't buy meat in the grocery store. Our favorite butcher has a refrigerated case and a chest freezer, but he does hang his cecina to air dry. He has better filet mignon that we can get in the US, then there are his ribs, carne enchilado, liver, heart, I'm drooling! The guy next to him does pork, and it's just as great. We think when you eat meat you should be aware that you are eating an animal, and appreciate it. We don't soak our meat, we usually marinate it but that's for flavor.

    Ranch cheese? Sure, we buy it, but from a cart that appears regularly, someone with a table in the market, not a random person.

    OK, chicken. Zihuatanejo has the most amazing chicken anywhere! We finally figured it out. It's sold in LOADS of little tiny places. A block of ice covered with a cloth, a person with a stick with tassels waving it over half a dozen dead chickens, gutted and plucked. They will cut you any pieces, filet and pound a breast, whatever you want. The livers are fabulous, so different tasting. When you get it in your hands, you realize it's not really cold. These are extremely fresh dead birds. The abattoir is in the center of the block with little tiny openings all around. The people are literally getting freshly butchered birds and selling them a few at a time. It's amazing in flavor and texture. It doesn't compare to any other chicken. Yes, as soon as we get it home, we refrigerate it, and we shop with an insulated bag with a frozen bottle in it.

    Where do we eat? Wherever it looks good, smells good and there are other people. Does this include street food? Yes. We probably have 4 meals out a week, generally breakfast, and two of those meals tacos of various types another quesadillas, I'm hungry!!

    When we lived in the US we found that we would have "intestinal upsets" occasionally from eating fast food. Here, we may have a meal that sits heavy, but considering how often we grab food out, we feel food handling practices are very good.

    So, what does this all mean?? Come to Mexico, have a great time, eat strange things, do fun things, enjoy our country.
  • I would say a large majority of RV'ers do not set up camp in downtown Mexico City, Monterrery, Guarajalara, or Puebla.

    And many do not have an inkling of hard info about storage of food.

    I haven't seen or talked to a gringo in Mexico in what six months? A year? But family and friends go through intestinal distress just like anyone else. It's just more important with a limited amount of vacation for tourists to avoid it if they can.

    I know of no one who has rethought about RV'ing in Mexico because of food worries. Just like I have never heard of anyone cancelling a cruise even though thousands have been poisoned with shipboard illness a hundred times worse than anything I have experienced or heard of in Mexico.

    What IS disgusting is seeing RV folks break legs and get electrocuted. "Where's Mary?"

    "Oh she has had a stomach bug for the last few days"

    Smart people avoid this
    What kind of people swear up and down it doesn't exist?

    Or recommend seeing a doctor for an Rx of ciprofloxacino antibiotic which can cut down recovery time by 90%.

    Or recommend hiring a carpintero to make a wooden box to replace suicide grade metal stairways that hurt the elderly.

    I had tennis shoes with felt glued to the soles (GOOP) for use on slippery cobblestone streets and slimy Mayan temple temple knee high half shoe length stone steps.

    Paranoia or intelligence?

    Low IQ people alarm prospective newbies with tales of disaster.
    High IQ people tell newbies how to minimize risks with simple work arounds.
  • At certain times of the year lettuce may originate in Mexico. But that does not make it bad! Produce that is exported is USDA inspected in the fields. Lots of requirements.sonora and Sinaloa even grow lots of Organic certified produce.

    Moisheh
  • Seafood is always best if you are near the sea...eating ceiviche from a street vendor in Mexico City hours from the nearest seaside...what do you expect?

    But no reason to be overly paranoid. If it were that bad, they would be running out of people in Mexico.

    I believe 95% of Montezuma's Revenge has nothing to do with contamination. All water and uncooked food has bacteria on and in it but the selection varies by location. Travelers simply aren't accustomed to the local variants. Mexico just got a bad reputation because far more travelers go south rather than north.

    PS: Reminds of the Christmas we spent in Merida. The grocery store (large, modern and clean) just put out a table and started throwing big chunks of unwrapped meat on it. I think it was beef but couldn't say for certain. It cooked up and tasted fine...and we survived.
  • This reminds me of a famous rver from a few years back that swore up and down at the time that ATMs didn't exist in Mexico although the person's experience was quite limited and traveled the most barren parts of western Mexico and just didn't know better. Vast generalizations.

    I don't care for these threads as it spreads some old myths as well as misinformation about Mexico and scares off possible Mexophiles.

    That said, the vast majority of Mexicans (77% live in urban areas) shop in supermarkets and are always careful about what they buy and eat.

    However many Mexicans and tourists eat on the streets daily using common sense rules.

    We may be behind in some things but we're definitely not living in the 1800s either.
  • And yet as a young NAVY man I wandered the streets of Tijuana/Ensenada MX, Olongapo PI, Kaohsiung Taiwan, Hong Kong eating BBQ from street vendors (some kind of meat grilled over an open fire), drinking Mai Tai that was made in a bucket, having meals with the locals (whatever they were offering), shopping for fish, chickens, pig in open air 'markets' and drinking water from hoses.

    I never got sick.......

    6 yrs later back in the States out on a date at a fancy steak house I get the worst food poisoning

    Haven't been sick since....not food poisoning, colds or flu.
