The Howard Mold counting technique is recognized internationally as a standard procedure for estimating the extent to which a product is contaminated with mold filaments. It is generally used in Tomato products.
Why?
The Howard count in turn can be related to the condition of the raw material as well as effectiveness of plant sanitation, particularly when such contamination is due to fungus type decay.
How?
This is a microscope slide method developed by BJ. Howard in 1911 primarily for the purpose of monitoring tomato products. The method requires the use of a special chamber (slide) designed to enumerate mold mycelia.
