Dairy company Lactalis Australia has announced a second milk recall in a week over fears about possible E.coli microbial contamination.

The milk being recalled includes 1- and 2-litre bottles of milk sold at Coles, Woolworths, IGA and other stores in Victoria.

The milk is also available in southern New South Wales, the Murray, Riverina and western districts of New South Wales.

Lactalis Australia warned consumers not to drink the milk because the contamination cannot be detected by taste, smell or sight and can make people sick if consumed.

The company has identified the source of the contamination "and has taken the necessary steps to address it and prevent any recurrence of this problem in the future", it said.

One type of Coles-brand milk sold at Victorian Coles Express sites and 4 Coles Express stores in southern New South Wales has also been recalled.

The affected products have a use-by date of July 2, 2019:
