Table 1.

Bacterial contamination in counts (log cfu/g) in soil/lettuce samples and counts in (log cfu/100 mL) wastewater samples.

Microbial (Bacterial) Count (log CFU/g)		Sample
Microbial (Bacterial) Count (log CFU/g)		Wastewater	Lettuce	Soil
Aerobic Plate Count	Recorded Count	5.80 ± 0.13	4.82 ± 2.55	6.14 ± 0.38
Aerobic Plate Count	Standard	NA	≤6.69*	NA
Total Coliform	Recorded Count	4.77 ± 0.45	3.50 ± 1.00	4.90 ± 0.15
Total Coliform	Standard	NA	<4*	NA
Faecal Coliform	Recorded Count	3.5 ± 1.00	<1	<1
Faecal Coliform	Standard	<3/100 mL^a	<2*	NA
Salmonella	Count	<1	<1	NA
Salmonella	Standard	<1	<1	<1

Values shown in the table are means ± standard deviation. The values with the superscript ‘a’ and * are standards from [37,38], respectively. APC: aerobic plate count; TCC: total coliform count; FCC: faecal coliform NA-not applicable.
