TAPESCRIPTS 

Listening Section 1 

In the mid²-1990s there was a new big, controversy³ that came in, wasn’t there, about 

genetically⁴ modified foods:  foodstuffs⁵ containing genetically altered plant or animal 

material. And it wasn’t long before an abbreviation came along to summarise⁶ all these: 

genetically modified – G.M. or "genetic modification⁷". Now that’s a pretty technical 

abbreviation; you might not expect to encounter it very often, but actually, you do. 

Because it was controversial at the time and people didn’t know whether to put this stuff 

into their foods or not (and it still is controversial), you began to see it on signs – 

Listening Section 2 

Because it was controversial at the time and people didn’t know whether to put this stuff 

into their foods or not (and it still is controversial), you began to see it on signs – 

especially after 1996, when the food labelling regulations came in, and they applied⁸ in 

Britain in, 1999 I think it was – and from that point on, people had to say, if you were a 

restaurant owner or a café owner, you had to say whether your foods had G.M. in them or 

not – and so you walk into a restaurant these days, and you might well see a sign on the 

wall saying "no G.M. foods here" or "the following foodstuffs have G.M. products inside".  

And people I've often asked them often asked you know, what do you think G.M. means?  

And they guess all sorts of things. Some people have told me it means "good morning 

food". Somebody else told me it was a "gold medal" food. Well – it doesn’t mean any of 

those things. It means "genetically modified", that’s all!
