Some 99.8 percent of fresh milk products in China were up to standard, according to the latest dairy quality spot check result Tuesday.
"The quality of domestic fresh milk products has never been better than today," said an official with the Ministry of Agriculture (MOA).
The spot check detected no illegal additives, such as melamine, according to the MOA.
The quality of milk and dairy products has improved as China has taken a string of measures over the past years, including improving regulations and industry standards, and tightening supervision.
The MOA has implemented specialized supervision campaigns for fresh milk products for nine years in a row.
The supervision covers more than 8,100 dairy farms, 5,400 fresh milk product purchasing stations and 5,200 transport vehicles across the country.
The country's milk industry has recovered from the 2008 safety scandal, when infant formula produced by Sanlu Group, then a leading dairy company, was found to contain melamine, killing six babies and leaving thousands seriously ill.
China produced 37.12 million tonnes of milk and 29.93 million tonnes of dairy products in 2016, ranking third after the United States and India.
