Table 2

Bacterial count (TBC and TCC) and drug residues in milk samples analyzed in this study.

Region		TBC; (±SE 10^7 cfu/ml)	TCC; (±SE 10^6  cfu/ml)	Tetracycline; % positive samples ()	Sulphur; % positive samples ()
Overall	327			16.9% (31)	42.1% (77)
Morogoro	103			25.2%	55.4%
Coast	80			6.3%	25%
Tanga	144			ND	ND

: sample size; TBC: total bacterial count; TCC: total coliform count; ND: not detected; (): percentage of samples tested positive on drug residues. Different superscripts within a column indicate statistical significance of values among regions ().
