Following requests from officials in the United States, Chinese authorities are apparently now making closer checks on food exports.
Chinese exporters have been asked to register with the government and adopt other measures in an attempt to provide greater assurance on the safety of their products.
The requests come after a series of problems with Chinese exports which have resulted in toxic materials being found in toothpaste, fish and pet food.
In fact the list of potentially deadly products being exported to the U.S. and other countries seems to be growing on a weekly basis.
Food items such as proteins and glycerine must now be checked after a run of health scares involving tainted Chinese-made products and companies are now required to tell Chinese customs when they export or import glycerine, and have it inspected.
Concern has arisen following a number of pet deaths due to tainted wheat gluten and rice protein exported from China used in the animal feed; even more alarming is that toxins such as diethylene glycol, a toxic chemical used in engine coolants, has been found in tubes of Chinese-made toothpaste sold in Australia, the Dominican Republic and Panama.
The toothpaste was supposed to contain glycerine.
The latest set of problems began in March, with the imported pet food ingredients which were found to be spiked with the industrial chemical melamine and related compounds.
The scare prompted recalls of pet foods but the list includes dirty mushrooms, drug-laced frozen eel and juice made with unsafe color additives.
