This follows a two day annual audit of the manufacturing facility in Driffield, which produces the brands Nature’s Feast, Peckish and Bucktons.
James Farnsworth, general manager at Westland said: "We are delighted to remain the only bird food manufacturer to achieve the BRC accreditation. The BRC is much more than just an accreditation for us. It’s about creating a culture in which everyone in the company recognises the importance of product safety and the quality of our products.
"The status, which we have achieved at Grade ‘A’ for the fourth year running, acts as an assurance to our customers that all our products, have been produced safely by experienced and professional staff, to the highest standards, using the best ingredients.
Keith Nicholson, marketing director at Westland said: "We remain the only manufacturer to actively drive awareness of the bird food sector in national advertising across the UK. We have invested in TV, print and magazine advertising to ensure that more people than ever realise the importance of feeding birds and flock to our retailers to buy our products. Last year alone, we invested £1m in TV and communications, achieving a sales growth of 148 per cent, compared to the previous year."
