231. MICHIGAN MATERIALS AND METHODS HANDBOOK J. F. PRICE MI CH I GAN STATE UN I VERSI TY ________-_----------------------------------------------------------------- I have been as-ced t o discuss the "Materials and Methods Hsndbook" under the general topic of Meat Extension Progrsms. As a matter of curiosity, I think that I should zttrmpt to relate just what the "Matcrlids and Methods Handbook" is, why it was prepared and what I think now - 3 ycax - after its preparation. In late 1962, Michigan Statc University entcrcil into contract with the Federal. Extension Ser-rice t o de-elop and conduct : I pilot extension program designed to instruct and train personnel concerned with the processing of meat and poultry toward thz adoption of processes, practices and techniques that would be of berxfit to the industry and society. One requirement was to prepwe a hzndbook of cases and approachc; tried. This then becme the "Materials and Methods Handbook". The trial. programs for extension training of meat processiw personnel were developed subsequent t o surveys of industry firms, problem and research. In contrast to the initial. survey type of economic analysis, the "Materials and Methods Handbook" approached the training of meat industry personnel fron: a more fundamental science and technology standpoint. The goals of the program were t o encourage adoption of processes and practices that would increase efficiency and assist firms with quality upgrading. Further the rlmpact of science and technology on the meat industry had resulted in a need f o r a new educational. approach t o a clientele with which we at the university level were only superficially acquainted. And t h c r r had been a reluctance on the part of some "traditionalists" to accept the challenge offered. Therefore one of the mutual objectives of the contract exercise was to stimulate activity of us extension specialists on behalf of a technologicaJ. revolution in meat processing. Approach : One premise was that there was a v d i d educational need among those in meat and poultry processing operations for new information (at least information new t o them). the basic scientific and technical principles with illustration of specific applications was of first order priority. Knowledge of the fundamental properties of the produ.ct, meat, of microbiological principles, of the effect of chemical and processing treatments, and of control of quality is valLiable t o processors. It enables them t o understand many of their problems, answers many of their questions, and makes it easier for them t o make certain diccisicns. My philosophy was, and still is, that teaching of This philosophy led t o the accumulation of the types of information incorporated in section I of t h e Handbook. A basic and perhaps simplified understaiding of what happens in the tissues post-mortem, of meat compositicn and structure, and of the reactions of particular components such as the pigments is critical to processors in explanation of why certain things happen and why some processes or procedures are or are not feasible.

Approach :

One premise w a s t h a t t h e r e w a s a v d i d educat ional need among those i n m e a t and poul t ry processing opera t ions f o r new information ( a t l e a s t information new t o them). t h e bas i c s c i e n t i f i c and t e c h n i c a l p r i n c i p l e s with i l l u s t r a t i o n of s p e c i f i c app l i ca t ions w a s of first order p r i o r i t y .

The thought of cost or p r o f i t control must never be l o s t , and some means of evaluating cost and re turns must be given adequate consideration.

Assessment of Act ivi t ies :

I. Survey of Michigan's Meat Supply and Processing Indus t r ies

Thus far I have been very general. Now l e t us t u r n t o an assessment of ce r t a in things we t r i e d . One thing we did t h a t proved t o be very helpful i n planning w a s an assessment of t h e po ten t i a l of d i f f e ren t segments of t h e meat industry within the bound of a pa r t i cu la r state. This w a s done i n con- nection with a college-wide program t o take a look at Michigan's ag r i cu l tu ra l po ten t ia l i n 1980, It forced us t o look at the types, s izes , d i s t r ibu t ion and po ten t i a l of m e a t processing firms. then be directed t o areas of grea tes t need and balanced with the competencies of extension personnel.

Emphasis of extension endeavors could

11. Case Study or Problem Solving i n Specific Firms.

An approach used w a s t h a t of working with spec i f ic firms and groups

This type of close contact enables of t h e i r personnel on c e r t a i n ideas or problems. This work could be labe l led , "Individual f i r m case-study approach". t he extension spec ia l i s t t o demonstrate methodology and philosophy i n problem solving and t h e need f o r technica l information and f a c i l i t i e s . provides an opportunity t o present and apply some of t he fundamental informa- t i on , hopefully, encouraging t h e management of t h i s f i r m (and t h a t of com- peting f i r m s ) t o fu r the r develop personnel and programs t h a t make fu l l use of technology.

Also, it

This case study or problem solving approach has disadvantages i n t h a t there may not be an opportunity t o present an organized program of per t inent information. Further, there i s a tendency t o over emphasize "the finding of a solution" t o t h e spec i f ic problem which can be of minor o r major importance t o the e n t i r e operation. And although or ig ina l contact may have been through top management, they frequently forge t t h a t t r a in ing i s t h e major purpose of t h e exercise.

111. Newsletters

Most of us use the "newsletter" or periodic mailings t o in s t ruc t or bring notice t o meat industry personnel. These are of varying types and use- fulness . It i s my candid opinion t h a t very l i t t l e education takes place through t h i s avenue. However, newsletters provide an excel lent means for reminding busy industry people t h a t the extension spec ia l i s t i s there and maintains an i n t e r e s t i n them. The periodic mailings of ten force us t o main- t a i n current l i s t s of act ive businesses and t h e i r categories of operation.

IV. Meat Science Workshops

Another approach which seems t o have resu l ted i n more continuing dialogue between univers i ty and industry personnel vas t h a t of holding "work- shops'' or classroom type t r e i n i n g sessions with smaller groups af personnel at a s i t e near t h e i r business locat ion. While some top-management personnel attended these sessions, as they were involved i n planning them, the t r z i n i n g w a s d i rected toward operations and qual i ty maintenance personnel. The grcsen- t a t i o n of selected subject matter w a s accomplished with t h e e id of s l ides , overhead transparencies, and demonstrations. The sessions werc generally 2-2 1/2 h r s i n duration concluding with an en thus ias t ic discussion period.

Group i n t e r e s t s must be taken i n t o account i n t h i s type of a c t i v i t y , a d t h e choosing of t o p i c s m d planning must include members of t h e spec ia l l n t e r e s t group a t hand. What I have attempted t o do over time i s accumulate and maintain a catalogue of s l ides , e tc . , i l l u s t r a t i n g basic pr inc ip les involved with such matters as - f reezing - precooking - t h e involvement of microbes and spoilage - sani ta t ion - product analysis - meat composition and character . Then these and selected reading or l e c t u r e mater ia l and demonstra- t i o n s can be organized and reorganized t o f i t p a r t i c u l a r audience needs.

Through t h i s avenue of t ra in ing , c loser contact with and involve- ment of individuals would be on t h e plus s ide . A mutual respect i s developed and a continuing rapport and dialogue ensues. On the other hand, the e f f o r t required t o prepare a s e r i e s of sessions f o r a s m a l l o r special i n t e r e s t group nay not always be j u s t i f i a b l e . And admittedly t h e s p e c i a l i s t i s concentrating h i s e f f o r t s for perhaps only a sub-segment of the industry. Topics of broad and general i n t e r e s t may be s l igh ted . Also it i s d i f f i c u l t t o publicize t h i s type of exercise because t h e t r a i n i n g w i l l not be designed f o r dl l e v e l s of industry personnel, yet care must be taken not t o exclude c e r t a i n people a r b i t r a r i l y . On occasion I have worked with groups composed of 14-20 people from a s ingle f i rm presenting a s e r i e s of workshop sessions. Extension administration needs t o be consulted p r i o r t o undertaking any arrangement of t h i s type i n order t o be consis tent with accepted policy.

V. Conferences

Yet another type of contact or another opportunity f o r t r a i n i n g i s t h a t of t h e organized conference. These a re usual ly held at a c e n t r d loca t ion (on campus) and involve several inv i ted program par t ic ipants . Goals, c l i e n t e l e and subject matter may vaxy widely. Ma~ly u n i v e r s i t i e s sponsor t h i s type of program. contact with industry leaders . These conferences are usual ly not g r e a t l y d i f f e r e n t from applied research conferences such as t h e Meat Ind. Res. Conf. For t h e most par t , all persons i n t h e industry are invi ted t o a t tend. The funct ion of t h e University i n providing a t r a i n i n g ground comes through most c lear ly , while both univers i ty and industry personnel s h x e r e s p o n s i b i l i t i e s f o r t h e program content. I am convinced t h a t industry leaders nust be i d e n t i f i e d and persuaded t o p a r t i c i p a t e i n planning these conferences Yor them t o be of maximum benef i t .

Our annual "Meat Processors Conference" has served well t o maintain

The ins t ruc tors presented t h e i r information from a cen t r a l campus loca t ion which w a s the recording s tudio of our audio-visual center. The se r i e s of programs w a s arranged much l i k e the weekly workshops previously discussed. presented on a specif ic evening f o r each of 4 consecutive weeks. matter w a s oriented toward plant sani ta t ion, microbiology and cleaning procedures. There were loca t ions or audience gathering areas i n each of 5 c i t i e s . Each loca t ion required a coordinator and a s e t of the v isua l a ids t o be used. Two way communication provided the audience the opportunity t o r e l ay questions back t o t h e l ec tu re r .

Two hour programs were Subject

This program reached an approximate t o t a l of 416 food industry workers o r managers most of which were associated with dairy processing plants . However, a few personnel i n the brewing, cereal , meat, egg and poul t ry process- ing indus t r ies did at tend and were encouraged t o do so. Costs have been estimated at 3 - $4,000.

The sessions were w e l l received by par t ic ipants who were mostly complimentary concerning the program and f e l t fu r the r t e l e - l ec tu re t r a in ing sessions should be held. Effect ive use of s l i d e s and/or movies w a s suggested f o r improving t h e presentations. It w a s evident t h a t e f fec t ive s l ide- tape presentations and b e t t e r coordination of on-site v i sua l a ids would add t o the value of t he te le - lec tures . I n a sense t h e " te le- lecture" exercise was an attempt t o reach a much larger audience with t h e concentrated e f f o r t s of several spec ia l i s t s . With an expanded audience f o r presentat ion of segments of a t r a in ing session, it i s eas i e r t o involve OUT teaching and research staff members. Hopefully there i s a l s o the incentive t o put fo r th grea te r e f f o r t i n preparing presentations and demonstrations - or t o make the pro- grams more polished and professional. e i t h e r for convenience or reuse.

Lectures could be taped and replayed

C onclu s ion:

I n s u a r y , all of t h e methods and techniques discussed may have spec i f ic appl icat ion i n meat industry-extension work. However, we cannot escape the f a c t t h a t t he extension spec ia l i s t must be capable, competent and wel l grounded i n the basic pr inc ip les of h i s selected science. It seems t o me t h a t OUT basic job i s t o develop t h e capab i l i t i e s and expert ise i n people i n m e a t processing firms -- e i t h e r through t r a in ing exercises f o r them or by leading the f i r m management t o recognize the need for and importance of technica l ly t ra ined personnel. Then they may seek t h e products of our

. un ive r s i t i e s - namely w e l l t ra ined students.

The problem of maintaining contact and communicating with in6ustry has been the most c r i t i c a l yet f r u s t r a t i n g problem f o r me personally. By some manner or means t h e extension spec ia l i s t s must maintain a dialogue with industry people. How best t o do t h i s , I ' m ce r t a in I don' t know f o r sure. Y e t we continue t ry ing and hopefully i n t h e ensuing discussion "all t h e answers" w i l l be presented.

BOB RUST: It wasn ' t necessary. A t t h e end of t hese f i r s t two years , we would probably have an i nd ica t ion of where w e would draw t h i s l i n e . This would probably depend on what type of information you research. I would c e r t a i n l y t r y t o be cooperative and perhaps make t h e information ava i l ab le at no cos t - - ju s t t o render t h i s s e rv i ce . A t t h e end of two yzars, we might be able t o bu i ld a case one way or t h e o ther f o r such charges. Hopefully, I t h i n k t h i s would be advisable .

I th ink , t c ge t back t o t h e question--we have t o develop and pick out leadersh ip and work with them and encourage them t o take t h e i n i t i a t i v e , because it i s t h e i r n i c k e l - - i t i s not mine, and if I had money invested i n t h e p lan t , then it might be a d i f f e r e n t s to ry .
