When a recall is initiated, it does not necessarily imply that a product is considered unsafe or is inefficacious. A recall can also be initiated to remove products with quality defects that does not impact safety or efficacy from the market so as to ensure that products registered in Singapore continue to meet the stringent regulatory standards stipulated by HSA.

Not all recalls will lead to press releases. However, when a recall involves a product that has been widely distributed or a product that poses a serious health risk, HSA will issue a press release to inform members of public.
