The problem of the foodstuffs’ hygiene, whether in the storage and in the stockpiling, or during the manufacturing in the food industries, has got an importance that does not decrease certainly during the time.
Data notified by the FAO underline how the damages of the parasites upon products picked up and stored take back unusable the 9% of the product, in the United States, whereas the 20% in the underdeveloped countries, carrying to the destruction of over one hundred millions of tonne of cereals stocked, for the cause of insects, rodents, birds, Mites and Mildews.
The abundance of food and the environmental conditions (generally in the food industries s used a conditioned atmosphere for the work that is maintained constant also during the cold season) results as very good elements for the reproduction of the infesting.
A HEARTFUL PROBLEM
If in the environments where the materials are stocked, in the stores for the conservation of sausage and cheese the problem is well known from a lot of years, in the industries where happen the transformation of the product, where are used establishments also technologically advanced, is however possible that the operators have not got a sufficient and specific and it is not correctly valued the possibility of infestation, and because there are a lot of places where these insects can place in a nest and find a favourable environment, the problem can be placed in an also massive manner.
Besides, systems usually operate 24 hours a day and it is difficult to effect intervenes, meticulous inspections and spring-Cleanings, and for this reason it is also not simple to realize an effective parasiticidal treatment.
In this last period of time we are oriented to the reduction in the usage of chemical means, and we point at the prevention and the control of critical points (HACCP regulations have signed the turn in this direction), but the fighting is surely very hard, and it does not permit the reduction of attention and negligence.
When, in addition to the foodstuffs’ parasites, the disquisition is enlarged to those insects that feed of detritus of these, is really strained the experience and the capability of pest-controller. Because the presence of organic fragments is not ever an index of negligence, or degradation: it results almost inevitable in some areas of the productive chain, unless these are not provided of aspiration implantations of great powerful, but really, in the majority of cases, it is different.
“The detriticulouses are not very “bad” Infestations, says Alberto Baseggio, of India, because they clearly show their presence. The parasites’ eggs are harder to fight and to find because they are not visible, and only when the goods arrive to the destination is discovered the presence of the larvae. With the damages that we can imagine.
HOW TO OPERATE
It is hard to flush out the detriticulouses, because they easily find the places where to hide, besides, the fact that usually the production happens consecutively does not permit a careful search and it does not facilitate the things. A precious rule remains ever to effect meticulous analysis on the raw materials that usually arrive to the industries already infected by the invisible eggs.
If the problem is showed, sometime it is necessary to apply to the help of chemical products: we can use formulation without solvents(for not having a smell) and residuals, using the moment when the system is stopped or the moments of conclusion upon the surfaces and areas without a direct contact with foods.
Among the products, India suggests Power Ac, photo stable pyrethroid with a knocked down and residual effect, with the base of alfametrina, active isomer, from the insecticidal point of view, among the isomer us is present in the traditional cipermetrina.
Maurizio Rigolli, of Bayer CropScience, observes how this is an important section, and it is still very important also to pay attention to the defence of the cereals, using phytosanitary products (as for example K Obiol), while for an environmental hygienic level, the action in the alimentary areas is integrated with the micro-encapsulated Aquapy. Obviously, with each product that is used, the first operation to effectuate, that if not actuated foil every kind of treatment, is a correct action of cleanliness.
In the case of Dermestes lardarius, and other foodstuffs parasites, adds Stefano Scarponi of OSD Ecotech (company that in the 2004 has realized a partnership with Lodi Italia, of the group Lodi International), we suggest the employment of pheromones with the relative distributing traps as system of monitoring and catch.
THE IMPORTANCE OF THE MONITORING
It is the proper and meticulous monitoring that is ever more important, that “reproduce” the real situation and allow, if necessary, to run for covers. “Some food industries, point out Baseggio, brightly act, the monitoring other than for the cockroaches and the common tined, also for the caltrops.
There will be some evolution in the future? This is a rhetorical question, because this is not a problem that we close in a drawer and is allow to settle. A promising development could arrive from the utilization of the IGR, the growth regulators, which actually are studied and if by now in Italy are above all utilized in the fighting against the mosquitoes, could represent a method. Not a miracle, undoubted, but another way to follow.
