So what is the risk? In one study "Mangoes, a mix of diced kiwi, cantaloupe and pineapple as well as a mix of diced pineapple, mango, grapefruit, kiwi and pomegranate did not support a growth potential that exceeded 0.5 log CFU/g over six days (Ziegler etal. 2018) However, another study showed that Listeria could survive on the outside of a kiwi for 30 days. . Yuan and Wang (2018) found that the "three pathogens [E. coli O157:H7, Salmonella spp., and L. monocytogenes] survived for up to 30 days on whole kiwifruit when stored at the room temperature, regardless of the inoculation levels and the kiwifruit variety. The survival of pathogens on fruit surfaces had been shown by other studies."
So from a retail sampling perspective, finding Listeria on a fruit that will not support growth is an issue for recalls. One can not overlook control of Listeria in the processing environment for products that will not support growth or have not historically had Listeria issues. One must consider that testing and finding Listeria on such products can result in a recall situation.
