The current opinion of state food protection directors toward certification was determined by a survey mailed to directors in each of the 50 states and the District of Columbia. There was a 96% return rate for the survey. Results of the survey reveal that 3 states (6%) have statewide mandatory certification programs; 17 states (35%) have voluntary programs; and 20 states (42%) have local jurisdictions with certification programs. A majority of directors (68%) would like to see either a mandatory or voluntary certification program in place in their state, and 73% of the respondents believe that certification programs do improve food handling practices. Barriers to developing statewide programs include financial resources, pragmatic design of training programs in rural states, and uniform requirements for certification. Respondents' comments are used to detail the implications of these barriers.

The induction of the male sexual organ primordia (antheridial hyphae) by the steroid hormone antheridiol in the water mold Achlya ambisexualis requires both transcription and translation. Inhibition of either of these processes eliminates the expected increase in the production and release of the enzyme cellulase, which accompanies the formation of the antheridial hyphae.
