*2.1.2. Hazard identification*

Farmers performing post-treatment would be exposed to pathogens in the compost. There are several groups of pathogens, but the pathogens of considerable interest in the study area are *Ascaris* eggs, viral infections (norovirus) and *Salmonella* because *Ascaris* and norovirus are also known to be the most resistant to treatment processes [11, 12]. Burkina Faso recorded 32.8% of bacteraemia among febrile children admitted to hospital (non-typhoid *Salmonella*) between 2012 and 2013 [2] and it is also reported that the carrier state of *Salmonella* typhi is defined as persistent shedding in faeces for greater than 12 months [2]. Accidental ingestion of a small dose consequently implies a high risk of infection compared to many other pathogens [10].
