I want to investigate the effect of Pseudomonas aeruginosa on Fusarium wilt of tomato. Pseudomonas aeruginosa, being a clinical organism, is it possible that it cause an infection on the consumer of such produce( tomato fruit)?
Dear Akanji
The oral infectious dose for this bacterium is thought to be very high, routes that pose the greatest health risk are skin exposure (for example, in contaminated hot tub water) and lung exposure from inhaling aerosols discharged from infected respiratory tracts.

Referring to the study, considering you certainly will work with health and adult individuals, I can't see any serious problem. An other consideration is that P. aeruginosa is not resistent to rises in temperature, perhaps envolved in the material preparation.
If you adhere strictly to Hygiene and bench safety rules and all workers are immunocompetent, it is no problem
Yes, P.aeruginosa can cause serious intestinal infection such as diarrhea in infants and many individuals if ingested with contaminated food. However, the infectious dose differ from one person to other. According to my experience we have isolated many cases of diarrhea in infants and other patients due to only P.aeruginosa which was demonstrated by presence of heavy growth in their stool.
