Arsenic prompts 'Pollen Allergy' product recall, Health Canada says

OTTAWA - Health Canada says a natural health product formerly named "Pollen Allergy" is being recalled because it contains unsafe arsenic levels.

The product is now sold as "Tongqiao Biyan Pian" and it has the natural product number NPN 80035736.

Testing done by Health Canada shows the product contains arsenic at levels that exceed the department's allowable limits.

It also contains an antihistamine and acetaminophen, the pain medication in Tylenol; none of these ingredients is listed on the product's label.

Health Canada says Pollen Allergy was widely distributed to retailers in Alberta, British Columbia, Manitoba, Ontario, Quebec, Saskatchewan and the Yukon by Wing Quon Enterprises of Richmond, B.C.

Consumption of arsenic by pregnant women can lead to pre-term births, stillbirths and miscarriage while children and adults exposed to arsenic may experience stomach pain, vomiting, diarrhea, muscle cramping and weakness.

Health Canada says it is monitoring the recall. It says people who have used Pollen Allergy and who are concerned about their health should contact their health-care professional.
