Possibly the mold came with the bamboo and there may be financial claims you can file in that direction.This class action lawsuit is for splitting, not mold, but it will give you an idea :  http://www.classactionsreporter.com/consumer/lumbe...I know there is another one for formaldehyde from China bamboo.  

An ozone generator should never be operated in occupied spaces, and the area should be adequately vented before people or animals are allowed to re-enter.According to a report produced by the EPA, ozone generators are ineffective at reducing levels of formaldehyde and carbon monoxide, despite claims by manufacturers.

It also gets rid of formaldehyde, bacteria, viruses and even VOC's. 

-JordanThe laminate from Lumber Liquidators should be avoided; they have been in the news about this problem of the offshore manufacturers producing laminate flooring products with excessive levels of formaldehyde. 

., another suggestion: Home Depot has Home Decorators bamboo by the pallet: it is a nice color (not too dark not too light), not really out-gassing, it is a 2-2.5 on the 1-5 hardness scale, it does not split that easy and is not involved in the formaldehyde lawsuits that lumberliquidators had for the similar bamboo...price is between hardwood and laminate.i'm on the first floor and i got this sandwich: concrete floor, 2x paint membrane, glued 6 mm cork, 3/4" plywood screwed into concrete, tar paper, bamboo on top nailed in.

It seems that Vinyl floors are highly toxic since they are made of PVC, Laminate flooring also toxic since they have formaldehyde and carpets are also toxic since they have fire retardants and stain resistant chemicals.

FYI Interesting segment on 60 Minutes tonight on Lumber Liquidators - Chinese made floor boards with very high levels of formaldehyde.

Airing out will do wonders and new flooring will have it's own smell as well, can't beat formaldehyde for hiding other issues.

Asbestos probably is on site, Lead paint for sure, formaldehyde in insulation...radon if there is a basement.
