I always hear that sound when opening containers of food products packaged with a good vacumn; sure the product has a good vacumn(seal)? I have in the past Cold packedVension and moose meat in 1 Qt Jars for preserving for later use and after boiling and sealing these jars via(in) the Open Kettle Method(boiling water) the Jar Lids would have a concave idencation after cooling, this concave dent indicated a good seal. When opening the Jars weeks or months later, the Lids would always make a popping or clucking sound when removing the lid.On a rare occassion when this sound was absent the concave indencation was usually absent and the meat was spoiled and had to be disposed in the garbage.Meat could be preserved this way for months without freezing, only stored at room temp.Look at Lid to make sure it has that concave dent otherwise the absence of the "Cluck" may indicate a bad seal.

On Sept 17, 2008: Senator John McCain said, as he had many times before, that he believed the fundamentals of the economy were "strong."Hours later he backpedaled, explaining that he had meant that American workers were Strong.

Like you id be thinking the product is a little iffy to consume.If the lid just flops off and there is no seal id think its not safe to eat.Some products have as you say a small concave and some will tell you that if its poped up and not sealed not to eat it as it may have been tampered with...or its spoiled.The seal is for more than design..its a saftey feature.

it may have something to do with altitude difference from where it was packed to where it was opened

That's what I was thinking, vicshere. Medellin is about 5'000 feet above sea level. There are indents in the caps so it would seem they are designed to be vacumned packed. But Peter makes a good point.

Now, what happened to the aluminum sheet that used to cover the top of the single beer cans? I think it was Pilsen that used to do that. Now I have to use the bottom of my shirt to wipe off the top of the can. Yeah, I know, I've got class, eh?

So, does Colombia have a health department that will go and inspect these food and grocery establishments? Is there a number where I may report my concerns? Do I risk being kidnapped?

I love this country!.....

Seriously, I really do.
