For both strawberries and raspberries, E. coli
O157:H7 levels decreased significantly (p b 0.05) after UV-C treatment,
with an average dose of 0.49 kJ/m2 (30 s treatment). After UV-C treatment
with an average dose of 0.92 kJ/m2 (one minute treatment),
E. coli O157:H7 levelswere significantly (p b 0.05) reduced on strawberry
surfaces, and remained constant until a four minute treatment was
achieved. For raspberries, significant reduction was achieved after 2
and 6 minute treatments, with no further reduction even up to a
12 min treatment time
