magazine suggest 14.7 million of the 63 million mobile phones in use in the uk today could be potential health risk.the most unhygienic phones had more than ten times the acceptable level of bacteria and seven of them were above the level. the worst phone also had 39 times the safe level of enterobacteria(肠道菌), a group of bacteria that live in the lower intestines(肠) of humans and animals and include bugs such as salmonella(沙门氏菌) . other bacteria including food poisoning bugs were found on the phones but they are at safe levels. which?
