They said the alliance will help both companies enter new geographic markets and the food supply and integrity segments in Mainland China, Hong Kong and Southeast Asia.
Test-it is the consumer product safety information platform under Vitargent.
Jimmy Tao, CEO of Vitargent, said it was an important milestone for the company.
"It is our goal to develop a comprehensive quality control system for product safety worldwide, especially for the vast consumer market in Mainland China.
“We hope to benefit every industry by helping them improve their quality of products with the application of the world's leading bio-testing technology and Test-it consumer product safety information platform.”
Vitargent will be publishing Test-it reports and safe-to-buy product lists so the public can access product safety information.
PwC Food Supply and Integrity Services was established in 2015.
Samie Wan, PwC Food Supply and Integrity Services leader, said: "Enhancing trust in food safety is a growing concern in a climate where public confidence in food producers, processors and sellers have been heavily disrupted in recent years.
“Despite the overall improvement of food safety and standards in many countries including China, the quality of many large-scale food companies remains unstable.”
Elton Yeung, strategy and innovation leader at PwC, said the partnership with Vitargent is about building trust in society.
"As our food supply becomes increasingly globalised, and the cycle of food production to consumption continues to change and evolve, the need to strengthen food safety systems in the supply chain and amongst countries is imperative.
“Leveraging PwC's global network and Vitargent's safety testing technologies, we are well positioned to safeguard and promote the importance of food safety and quality, and increase general consumer confidence."
