Hi joelchenda,
Normally I would expect you to have a raw material specification that covers this requirement. This specification may be from your supplier and approved by yourself or if you generate your own raw materials specifications then you should have documented confirmation from your supplier that they agree to meet the specification.
The specification should include the following as appropriate (from Clause 8.5.1.2):
a) biological, chemical and physical characteristics
b) composition of formulated ingredients, including additives and processing aids;
c) source (e.g. animal, mineral or vegetable);
d) place of origin (provenance);
e) method of production;
f) method of packaging and delivery;
g) storage conditions and shelf life;
h) preparation and/or handling before use or processing;
i) acceptance criteria related to food safety or specifications of purchased materials and ingredients
Based on your hazard analysis and intended use you will need to decide what acceptance criteria you want to apply, this may be micro limits, temperature on arrival, absence of antibiotics etc.
As an example, if you are simply portioning and packing raw chicken then your raw materials specification needs to at least match your end product specification unless you are reducing any hazards such as reducing microbiological loading by washing.
Kind regards,
Tony
