The warning about the sale of local Cheese Curds has been expanded.
The Canadian Food Inspection Agency says a second batch of curds sold by Primeridge Pure near Markdale may be contaminated with listeria.
The Primeridge Pure brand Pure Cheese Curds were sold at the Owen Sound and Collingwood Farmers' Markets and also at the company's location on July 16th.
The affected product bears the words "packed on 15.07.11" -- and was sold in packages of various weights.
The first recall affected products stamped with the wording "Packed on 08.07.11''.
There have been no reported illnesses associated with the Cheese Curds -- but Primeridge Pure has decided to halt production temporarily.
CFIA Food Safety Recall Specialist Fred Jamieson says they are still looking for a source of the contamination.
He tells Bayshore Broadcasting News the cheese curds may not look or smell spoiled -- but if consumed -- it may cause listeriosis.
The disease can cause high fever, severe headache, neck stiffness and nausea.
Pregnant women, the elderly and people with weakened immune systems are particularly at risk.
