E. Coli Infection After Breast Reduction?

E. coli is an enteric bacteria - the other answers describe potential sources for this bacteria.  Regardless, the more pressing issue is to have your infection treated appropriately.  I trust that you are also being followed by your plastic surgeon, and with such, ensure that you are on appropriate antibiotics specific for this bacteria, as it will not be covered by the typical antibiotics used to treat skin infections.  Moreover, your surgeon will evaluate your wound and determine the progress of the treatment along with the possible need for surgical intervention if the wound fails to progress with appropriate therapy or worsens.  Good luck!

I'm sorry to hear about the complication you have experienced  after breast reduction surgery. At this point, it may be very difficult to ascertain the exact source of the E. coli bacteria;  online consultants can only speculate.

 Also, at this point, the most important thing is that you be treated appropriately with close follow-up with your plastic surgeon. Appropriate antibiotics (tailored to culture  and bacteria sensitivity results),  drainage procedures, dressing changes etc. may be necessary.

 Hopefully, once this infection is resolved, you will be pleased with the long-term outcome of the procedure performed.

Best wishes.

It is unusual to have an infection after a breast reduction, but it can happen. The most important thing is to treat it with antibiotics and get the wound clean.  Follow closely with your surgeon.
