This report is one of the deliveries from the project “Risk assessment of by-products from the

food and nonfood industry used for the feeding of food producing animals in relation to food

safety and animal health”.

The project and the report aim to provide both the feed sector and the feed and food authorities

more knowledge about the potential risks to food safety and animal health which can be

related to the use of by- and residual products as feed for food producing animals. Another

important goal is to create awareness of the subject with businesses that do not deal with feed

and food as their main activity, but that in the future might become suppliers of by-products

for animal feed - this is aimed mainly at the nonfood industry, e.g. the biofuels and pharmaceuticals


The report explains the background for the project and clarifies what is meant by the term

by-products. It includes a review of the different types of risks (physical, biological, chemical),

and a brief introduction to risk assessment methodology. The main focus is the chemical

risks related to the use of the different categories of by-products: 1) Vegetable by-products;

2) animal by-products; 3) by- or residual products from the production of food, and last but

not least 4) by-products from the production of nonfood especially from the biofuel industry.

The report provides information on the feed relevant alerts in the EU's rapid alert system

(RASFF) in 2008 - 2010. Furthermore, the report recommends consideration of a number of

specific issues related to the "story" of the by-product that may help to uncover whether a

specific by-product could be considered safe feed. These considerations can clarify the further

investigations (e.g. analyses) that are needed to ensure that the by-product will not constitute

a danger. "Story" means the entire process from the origin of the raw materials, the

manufacturing process that forms the basis for the formation of the by-product, the subsequent

management and possible further processing, storage/handling/distribution in all stages

until the delivery of the by-product to the end user.

The report presents results of the calculations of different cases where food producing animals

have been fed with rations including normal to high amounts of selected contaminants

in different combinations as follows: 1) Pesticides in citrus pulp; 2) arsenic in fishmeal and

3) mycotoxins in dried distillers grains and soluble (DDGS-wheat) from production of the

first generation bioethanol. Such assessments of different selected cases can provide focus on

and uncover any potential risk to animals and humans when a specific by-product is used as

feed. These assessments can also form a basis for considerations and measures to reduce the

risk related to the use of the by-product.

The report deals with future expectations regarding the amounts and types of by-products

suitable for feed purposes and gives examples of alternative routes of distribution other than

the traditional feed industry.

By- and residual products from the food and non-food industry currently account for a noteworthy

part of the feed for food producing animals. The intensified demand for raw materials

used for food, feed and biofuels is expected to lead to an increased use of by- and residual

products for feed purposes. These are the products we know today as well as new coming

from e.g. the non-food industry. The greater competition for resources, the greater attention

should be paid to the potential risks to animal health and food safety that may follow the use

of by-products for feed purposes.
