Every bottle of blood manufactured by Pigs Might Fly South will be marked clearly with a Best Before End (BBE) date, in accordance with Cosmetic Regulations.

All of the blood products are given an 18 month BBE date from the date of manufacture; if stored correctly, and in accordance with the instructions given on the label on the bottle, the blood will not deteriorate and will be safe to use until the BBE date. The blood should be stored in closed bottles, out of direct sunlight, and preferably in cool room temperature conditions. Blood that has been decanted from a bottle should not be returned to the bottle in case it has become contaminated which could cause the remaining product to deteriorate.
