Look at larvae and pupae remains
When larvae and pupae killed by AFB dry out and turn to scale, their flat shape can make them difficult to identify. Remains of larvae can be especially hard to see, since the scale lies completely flat along the lower wall of the cell.
Remains of pupae are generally easier to identify, since a thin thread (which is the dried remains of the pupal tongue) can sometimes be seen pointing directly across the face of the cell, from the bottom angle to the top angle of the hexagon (Fig. 1 and 17).
Seeing a tongue, either in a moist, coffee-brown coloured sunken pupae (Fig. 1), or in pupal scale (Fig. 17), is a definitive diagnosis of AFB, since no other disease is likely to produce such a symptom.
The presence of a pupal tongue stretching across the cell can be used to reliably diagnose AFB.

There’s a lot of good information here, telling you everything you need to know about recognising AFB: the visual symptoms, smell of AFB and more.
New Zealand beekeepers have a number of legal obligations that must be met regarding AFB disease. Read the shortened list in summary, here.
Most hives become infected because bees, honey or equipment have been put into a hive from another hive that is infected with AFB. Lower your chances of an AFB infection by reading this section.
