EC Health Marking requirements

Please can someone give me some guidance.........

I have had a new tech manager start while i have been away from site for a week and this guy wants to change the world.

Health marking - he has stopped using a small EC tape on bagged products of chicken pieces due to size of the text apparently and told them to use a differant size tape e.g. bigger .

we have used this tape and text size for 5 years and nothing has been raised with the vet, customer. He says there is a regulation stating the size of text required but i cant find this. i have only found what is in this reg

Corrigendum to Regulation (EC) No 853/2004 of the European Parliament and of the Council of 29 April 2004

laying down specific hygiene rules for food of animal origin

Please can someone guide me

thanks

Can anyone help Aps with this?
