Food Safety Act 1990

21 Defence of due diligence

(1) In any proceedings for an offence under any of the preceding provisions of this Part (in this section referred to as “the relevant provision”), it shall, subject to subsection (5) below, be a defence for the person charged to prove that he took all reasonable precautions and exercised all due diligence to avoid the commission of the offence by himself or by a person under his control.

(2) Without prejudice to the generality of subsection (1) above, a person charged with an offence under section 8, 14 or 15 above who neither—

(a) prepared the food in respect of which the offence is alleged to have been committed; nor

(b) imported it into Great Britain,

shall be taken to have established the defence provided by that subsection if he satisfies the requirements of subsection (3) or (4) below.

(3) A person satisfies the requirements of this subsection if he proves—

(a) that the commission of the offence was due to an act or default of another person who was not under his control, or to reliance on information supplied by such a person;

(b) that he carried out all such checks of the food in question as were reasonable in all the circumstances, or that it was reasonable in all the circumstances for him to rely on checks carried out by the person who supplied the food to him; and

(c) that he did not know and had no reason to suspect at the time of the commission of the alleged offence that his act or omission would amount to an offence under the relevant provision.

(4) A person satisfies the requirements of this subsection if he proves—

(a) that the commission of the offence was due to an act or default of another person who was not under his control, or to reliance on information supplied by such a person;

(b) that the sale or intended sale of which the alleged offence consisted was not a sale or intended sale under his name or mark; and

(c) that he did not know, and could not reasonably have been expected to know, at the time of the commission of the alleged offence that his act or omission would amount to an offence under the relevant provision.

(5) If in any case the defence provided by subsection (1) above involves the allegation that the commission of the offence was due to an act or default of another person, or to reliance on information supplied by another person, the person charged shall not, without leave of the court, be entitled to rely on that defence unless—

(a) at least seven clear days before the hearing; and

(b) where he has previously appeared before a court in connection with the alleged offence, within one month of his first such appearance,

he has served on the prosecutor a notice in writing giving such information identifying or assisting in the identification of that other person as was then in his possession.

(6) In subsection (5) above any reference to appearing before a court shall be construed as including a reference to being brought before a court.
