OTTAWA -- A Quebec company has expanded its recall of cleaning products due to microbial contamination.

Avmor Ltd. is recalling four more batches of the product X3 Clean Alcohol-Free Foaming Hand Sanitizer.

Last month the Laval, Que.-based company recalled a similar product, Antimicrobial Foaming Hand Soap.

At the time of the earlier recall Health Canada said testing showed the soap contains the bacterium Pseudomonas aeruginosa, which poses a serious health risk, particularly to people with weakened immune systems.

With this latest recall Health Canada says Canadians should consult their health-care practitioner if they have bought or used either of these two hand hygiene products.

It says that is especially true for people with compromised immune systems, including those with cystic fibrosis, HIV-AIDS, cancer, burns, diabetes and severe lung disease.

Health Canada says no adverse reactions related to use of these products has been reported to date.

The department is monitoring the additional recalls as well as the company's investigation into the root cause of the contamination.
