What the study seems to implicate is a lasting effect of the residues in meats. What I have noticed is that over a period of time, such residues can create enough imbalance as to cause problems. That can be a year or two of consumption of conventionally raised meats, typically. It could be less. It could be more. I think less is the way it will continue to go as farmers are dumping more and more antibiotics into animals. Animals who are given antibiotics tend to have more diseases and farmers responded by giving more antibiotics. All the more reason to switch to organic meats as much as possible.
