The melamine-tainted food scare just keeps on spreading. Hong Kong said tody that it is expanding its testing to include meat products imported from China after discovering excessive levels of the chemical in eggs yesterday.

The eggs, from Dalian Hanwei Enterprise Group, contained 4.7 parts per million of melamine, almost double the permitted maximum of 2.5 ppm, though only a hundredth of the levels found in some tainted diary products. The suspicion is that the contamination came from feed given to chickens that laid the eggs.

Last week, China’s health ministry said that more than 3,600 children remain sick after consuming melamine-tainted formula. Three are in serious condition.
