Fresh-pak Chilled Foods Ltd has become the latest supplier to gain British Lion certification.
Fresh-pak is the UK's largest producer of hard-boiled eggs, supplying between four and five million every week from its South Yorkshire base.
With a rising demand for eggs in pre-prepared foods, such as protein pots, the chilled food manufacturer has become the ninth processed egg supplier to become a fully certified member.
Catherine Clarke, spokesperson for Fresh-pak, said: "We pride ourselves on offering our customers the very best quality products so we're delighted to achieve British Lion accreditation.
"There is strong demand for British Lion quality processed egg as it's widely recognised by consumers, caterers, food manufacturers and retailers for its high quality and food safety guarantees. We are thrilled that we can now offer the assurance of the Lion to customers."
Ian Jones, Chairman of British Lion egg processors, said: "We are delighted to have Fresh-pak on board as an accredited Lion supplier. We now have more Lion egg products processors than ever before, which is great news for customers who wish to source Lion as there is even more availability.
"The use of eggs in pre-prepared foods is growing and with the Breggsit storm brewing, bringing with it issues around surety of supply, not to mention the ongoing food safety issues associated with imports, it's a good time to join as demand for Lion egg products is strong and will only get stronger."
