How can you tell if your beer is contaminated with bacteria? Are there any tell tale signs?

Smell and taste. If it's contaminated you'll know it. Even if it is bad (unlikely), it's not likely to be something that will make you sick.
Norovirus?
It spreads like mad and can be caught pretty easily. Comes on fast - and hard, leaves rather quickly (24-48 hrs).
I don't think it can live in beer, but it can live in/on many other things that we touch and eat all day - especially of you eat out.
Doubt it was the beer, I could see too much yeast giving you the "sneeze-and-change-your-pants blues."
Wouldnt a bacteria infestation stop the fermentation?
Its in the keg, had three pints the other night. Got really sick for 24 hours vomiting and such. The beer is drinkable but there is a funny aftertaste. I just wonder if its the beer? Cleaned and sanitized the keg with pbw before racking its been on co2 for about two weeks. But I really think that might be what got me sick.
BTW, WellShooter, the Flu shot does contain weakened and dead Virus. it is stated before ANY vaccine that it could cause symptoms or even sickness.
Call me crazy....

Get it straight people, no known pathogens can grow in your beer....nothing in your beer can kill you. Or make you sick!!!!!
In fact it was because water was often dangerous to drink that brewing became popular to begin with, because the brewing process killed most pathogens including e-coli
That's why the even brewed table beers, the third runnings from a partigyle session so that the children could have a drink that was safe to consume....
I came across this from a pretty well known and award winning homebrewer railing against a fellow brewer (it was on one of those "color coded" brewboards where they are a little less friendly than we are.) I just cut and pasted it and stuck it in a file...here it is.
Can you get a PATHOGEN from beer. No. NO *NO* Did I make that clear? You have a ZERO chance of pathogens in beer, wine, distilled beverages. PERIOD!
Pathogens are described as organisms that are harmful and potentially life threatening to humans. These are some 1400+ known species overall encompasing viruses, bacteria, fungi, protozoa, and helminths. Of that group, we are only interested in those that can be foodborne. Quite simply, if it can't survive in food, it isn't in beer. That knocks out all but bacteria and fungi. Viruses need very specific circumstances to be passed around... like on the lip of a glass or bottle, not the beer in it. **Ahhh...CHOOO!**
Pathogens as a rule are very fastidious beasts. Meaning that they want very specific temperatures, acidity, nutrients and other conditions to thrive.
Bacteria that *could* live in wort, cannot survive even a little bit of fermentation. There are several reasons for this. One is in the 'magic' of hops. It is the isomerized alpha acids that provide a preservative effect to the beer, which happens to inhibit pathogens! Good deal for fresh wort!
Another reason is the drop in pH from fermentation. Next, yeast emit their own enzymes and byproducts, all in an effort to make the environment hostile to other creatures. The major one is alcohol, of course, but their enzymes will break down less vigorous organisms and they become sources of trace nutrition. Now the latter is very minor compared to the effect of alcohol, but it exists! Most of the time these enzymes work on the wort, not organisms until late in the process. Good deal for beer! ...uh, wine too.
Oh, Botulism specifically... did you know that this is an anaerobic pathogen? It's toxin is one of the few that is broken down by boiling. Did you know tht it is strongly inhibited by isomerized alpha acids, even in water? Since fresh wort has a healthy amount of oxygen in it, the beastie cannot even get started, then once the O2 is used up, it doesn't have a chance against the hops or the yeast.
All that is left are a handful of acid producing bacteria that'll ruin a batch of beer. Overall, there are less than 200 organisms that can survive in beer and lend flavor effects. None of these for very long, or very often. Lambic being the sole exception, and if pathogens *could* survive, that'd be the style where you find 'em.
Engrave this in your mind, and tell your fellow homebrewing buddies to ignore idiocy like this thread....If something toxic could come from our homebrewing, it wouldn't be a legal hobby!!!!! It would be like distilling.....illegal.
Don't forget, we had to go through a hellova lot of hurdles to get it re-legalized, 40 years after prohibition was rescinded...If it weren't safe then it wouldn't be happening for us.
Also, remember, we're NOT doing anything different than the big brewers are doing...We make beer the same way, with the same processes and ingredients that the commercial and micro breweries do....only on a smaller scale. Just keep that in perspective, we're not making poison, even ACCIDENTALLY. We're making food.
Actually we are making something safer than food. As canners know, or picnickers with potato salad, sometimes FOOD can turn on you. Not so with beer, wine, cider OR mead. The were meant to be safe in times when even water was dangerous. Even an ifected beer is not pathogenic to humans...it might be nasty but usually the nasti-ness would prevent us from even bringing it to out lips to begin with.
