How likely is Huel to contain harmful levels of bacteria?

I read a few days ago that certain processed foods have been found to contain high levels of pathogen-associated molecular patterns (PAMPs), which have various negative health implications. Does anyone know how likely this is to apply to Huel?

Very unlikely as Huel ingredients undergo rigorous testing and the type of ingredients are very different to processed tray meals.
