How do bees get EFB?

EFB infection starts when larvae ingest the bacteria which can be present in the brood food, or can be transmitted from infected nurse bees. The bacteria then multiply in the mid-gut of infected larvae. The multiplying bacteria compete with the larvae for food, often causing the larvae to die before capping.

Does EFB smell?

The smell of EFB infected larvae is sour and urine-like, and is not similar to the fishy smell associated with AFB. However, because of the variability in people's ability to detect and differentiate odours, smell should never be used to diagnosis either disease.
