Garlic oil (or onion oil) when used in the proportion of 1500 μg per g of meat slurry inhibited toxin production by Clostridium botulinum type A (strain 73A). The inhibition, however, was not complete. Toxin production by C. botulinum type B (strain RIV 1) and type E (strain RIV 2) was not inhibited. It is not recommended that these oils be used for inhibiting toxin production by C. botulinum, as meat and meat products can contain several types of Clostridium sp. and not just type A.
