In unveiling the data, the European Commission says a key challenge is the increasing share of products bought online from outside the EU.
The Rapid Alert system, set up in 2003, ensures that information about dangerous non-food products withdrawn from the market or recalled anywhere in Europe is quickly circulated between member states.
Reaction to the findings was swift, with European justice, consumers and gender equality Commissioner Věra Jourová, saying, "The Rapid Alert system has helped coordinate quick reactions between consumer protection authorities to remove dangerous products across Europe."
Speaking in Brussels, she added, "Two challenges lie ahead of us: online sales bringing products directly to consumer's houses through mail and the strong presence of Chinese products signalled through the Rapid Alert system."
The official, who will seek to step up EU cooperation with the Chinese authorities on product safety in a visit to China in June, said, the EU and businesses are working together to ensure that unsafe consumer goods are removed from the European market.
In 2015, there were 2072 alerts and 2745 follow-up actions registered in the system. When one member state posts an alert on the system, other countries can spot the product on their market and react to this initial alert.
Over 65 per cent of Europeans buy products online and the number of online shoppers has grown by 27 per cent between 2006 and 2015.
On Monday, the Commission said the challenge now is to "address the online channel, which also brings products from outside the EU through mail into consumers' households that may not have been subjected to safety verification."
Action on this already includes cooperation with border control staff and online selling platforms.
In 2015, toys (27 per cent) and clothing, textiles and fashion items (17 per cent) were the two main product categories for which corrective measures had to be taken. These were already the most notified products the year before.
The most frequent chemical risks notified in 2015 related to products such as fashion jewellery, with harmful heavy metals like nickel and lead, and toys containing phthalates.
With 62 per cent of the notified dangerous products coming from China, the country remains the number one country of origin in the alert system. It is also the EU's largest source of imports.
The Commission says that collaboration with the Chinese authorities "continues to be a priority" for the EU.
To date, China has followed up on as many as 11,540 notifications and has been able to take corrective measures in 3748 cases. In many cases, tracing the source of the product remains difficult.
