Robert,
You can try ventilating the house with fans. But most of these cases end up in litigation, so you or the homeowner may want to consult a lawyer. For more information, see Spray Foam Jobs With Lingering Odor Problems.

There are many articles written about a strong fish smell that is known as off-gassing. Spray foam insulation is a two part mixture that if not mixed at the right levels or temperature, will release an odor that lingers for quite a while. Some of it back in the days contained formaldehyde although spray foam dealers have turned to other chemicals containing soy products to minimize the smell.
