transport
Samples must be transported under appropriate conditions to the laboratory in clean container and robust packaging. Polythene or polypropylene bags, ventilated if appropriate, are acceptable for most samples but low permeability bag (e.g. nylon film) should be used for samples to be analysed for residues of fumigants. Samples of commodities pre-packed for retail sale should not be removed from their packaging before transport. Very fragile or perishable products(e.g. ripe raspberries)may have to be frozen to avoid spoilage and then transport in dry ice or similar, to avoid thawing in transit. Samples that are frozen at the time of collection must be transported without thawing. Samples that may be damaged by chilling (e.g. bananas)must be protected from both high and low temperatures.
