In the second study, Orientation of Salmonella Contaminated Tomatoes under UV-C Light
Figure 1 show The positions of marked inoculated tomatoes under UV-C light (as viewed from top).
circles represented the inoculation sites (A).
Salmonella contamination positions on tomato surfaces:
1 – directly exposed to UV source
2 and 5 – on equatorial plane facing reflective side wall of UV protective shield
3 – on equatorial plane facing tomatoes
4 and 6 – on equatorial plane facing reflective end walls of UV protective shield
