Procter & Gamble (P&G) Vietnam has notified health authorities that it will recall two mouthwash products they suspect of being contaminated, the Drug Administration of Vietnam announced on July 19.
The company did not specify the recall date or how much of the contaminated product has already entered the market, the agency said.
During its recent announcement, Oral-B ordered a recall of its Tooth and Gum Care Alcohol-Free Mouth Rinse and Oral-B Tooth and Gum Care Mouth Rinse (350ml and 500ml).
P&G Vietnam representatives said the move was made after the multinational parent company initiated a voluntary recall of the products, manufactured in Retycol, Columbia, from shelves in Mexico, Chile, Columbia and Canada last week.
According to P&G Vietnam, the voluntary recall is a precautionary step after periodical tests detected microbial levels that exceeded company specifications in the products.
Although it has ordered a recall, the company affirmed that the microbes pose no safety risk to healthy users.
However, in a separate statement, P&G admitted that people with "severely weakened immune systems, such as those with cystic fibrosis, may be more susceptible to adverse health effects" from using the mouthwash.
P&G Vietnam also notified its distributors and retailers that consumers who have purchased the products may return them for a full refund.
Local doctors have advised consumers to use the products with caution.
"Using mouthwash is not the best way to protect your teeth and mouth, or a substitute for teeth cleaning," said Dr Yen Lam Phuc of the Vietnam Military Medical University.
Since the products contain antiseptics and antibiotics, excessive use can lead to allergies and worn-out teeth, he noted.
"Children who unintentionally swallow mouthwash liquid suffer from digestive disorders," said Dr Vo Truong Nhu Ngoc of the Hanoi Medical University.
