A recall on Neilson brand chocolate milk due to listeria concerns has been expanded to include additional formats.

A recall issued June 3 for 4 L bags of the chocolate milk with the best before date of June 1 has now been expanded as follows:

4 L with a best before date up to and including June 22

2 L with a best before date up to and including June 22

1 L with a best before date up to and including June 22

750 ML with a best before date up to and including June 22

473 ML with a best before date up to and including June 22

237 ML with a best before date up to and including June 22

The products were distributed in Quebec and Ontario.

Parent company Saputo said some recent cases of listeria may be connected to the products, which should be thrown out or returned to the store where they were purchased for a refund.

Listeria does not necessarily cause products to change in appearance or smell.

Possible symptoms include vomiting, nausea, fever, muscle pains, severe headaches and stiff neck.

In severe cases, listeria poisoning can be fatal.
