[Health-related evaluation of plant protective agents in drinking water].

Crop protection products are anthropogenous substances that should have no place in drinking water. Some of them are long-lived, can accumulate and are poorly biodegradable and many of them are not so harmless to human health as would be desirable or necessary. Accordingly, Federal German legislation provides for limit values of crop protection products close to the identification limit. Although it does not appear justified to close down waterworks effective 1 October 1989 if these limit values are exceeded, it must be carefully considered up to which concentration--depending on the individual substance--special permissions can be granted for a limited period of time. It seems that such concentrations should preferably be in accordance with general food legislation. Recommendations will be shortly issued by the Federal Health Ministry. The fact that special permissions are at all under consideration to prevent complete closing down of water supply reservoirs should sound a note of warning to all concerned, including crop protection product users and the relevant Government agencies issuing special permits.

Polyols in confectionery: the route to sugar-free, reduced sugar and reduced calorie confectionery.

Polyol-containing confectionery offers considerable advantages over traditional sucrose-based confectionery in terms of reduced energy content and reduced cariogenicity. However, over-consumption of polyol confectionery may lead to gastrointestinal symptoms in some individuals. Rather than consider this as a distinct disadvantage to the consumer, this article discusses how careful consideration of the physico-chemical properties of polyols and advances in product development and formulation can provide suitable polyol-based products for the consumer. Furthermore. food legislation and ingredient pricing issues are just some of the factors that must be taken into account when designing new polyol-containing products if their functional benefits and good product quality are to be delivered to the consumer.

[Microbiological condition of bottled natural mineral waters, drinking water, as well as water from mineral springs].

We are now in the midst of a critical discussion on the microbiological quality of bottled natural mineral water, springwater, so-called "table water" and drinking water. "Still" waters have high colony counts after long storage, whereas in carbonated bottled products multiplication of oligocarbophilic microorganisms is suppressed by carbon dioxide. Opportunistic species are also found in bottled water. Present knowledge as to whether they are contaminants or part of autochthonous flora is insufficient. Highly colonised foodstuffs and opportunistic species may be hazardous for immunosuppressed patients. Hence, it is claimed that existing legal microbiological criteria for bottled water are inadequate. High colony counts in foodstuffs do not necessarily imply poor microbiological quality a priori. Detection of an opportunist species does not justify classifying a food item as hazardous. Microbiological criteria for bottled water which are laid down in the Directive for Mineral and Table Water of the German Food Legislation Act (LMBG) were established based on recommendations by international microbiologists for the normal not oversensitive consumer. For more sensitive groups of consumers, for example babies, more severe criteria were set up. Immunosuppressed patients are another sensitive group, demanding special hygienic requirements for their surroundings. If the risk of infections for immunosuppressed patients cannot be reduced by other means, it might be useful to establish microbiological criteria for bottled water and of course for other foodstuffs as well. However, such criteria cannot be adequately applied to food for normal consumption, since otherwise many foods would have to be regarded as hazardous and could not be marketed because of legal prescriptions.

Regulatory considerations on transgenic livestock in Japan in relation to the Cartagena protocol.

In Japan, the development and application of living modified organisms (LMOs) are regulated by law (conservation and sustainable use of biological diversity law). Procedures are classed as type 1 for the use of LMOs where no preventive measures against their dispersal into the environment are required and type 2 for the use of LMOs where preventive measures are stipulated. Development and research on transgenic livestock falls under the responsibility of the Ministry of Education, Culture, Science, Sports and Technology. Field use of transgenic livestock is controlled by the Ministry of Agriculture, Forestry and Fisheries. The author describes risk assessment and management of transgenic livestock by both ministries.

Mediterranean countries impact on the implementation of Council Directive 91/414/EEC.

For the implementation of the Framework Council Directive 91/414/EEC, participation of all member states (MS) is required. In the first round of the review program of plant protection products, Mediterranean countries have successfully performed their proportional work share for the central registration of the active substances and the national registration of the respective plant protection products. However, some issues of risk assessment, related to appropriate estimation of exposure, still require further refinement and adaptation to the Mediterranean conditions. Issues related to the estimation of agricultural worker exposure to plant protection products due to different agronomic practices and conditions, identified shortcomings in the consumer risk assessment related to different habits of the Mediterranean population and different needs of Mediterranean agriculture will be discussed. Finally, the possible effects of the Directive 91/414/EEC upon the plant protection of Mediterranean countries, due to the withdrawal from the market of a wide range of plant protection products is also a parameter that has to be considered.

Ecological-friendly pigments from fungi.

The dyestuff industry is suffering from the increases in costs of feedstock and energy for dye synthesis, and they are under increasing pressure to minimize the damage to the environment. The industries are continuously looking for cheaper, more environmentally friendly routes to existing dyes. The aim of this minireview is to discuss the most important advances in the fungal pigment area and its interest in biotechnological applications. Characteristic pigments are produced by a wide variety of fungi and the chemical composition of natural dyes are described. These pigments exhibit several biological activities besides cytotoxicity. The synthetic pigments authorized by the EC and in USA and the natural pigments available in the world market are discussed. The obstacle to the exploitation of new natural pigments sources is the food legislation, requesting costly toxicological research, manufacturing costs, and acceptance by consumers. The dislike for novel ingredients is likely to be the biggest impediment for expansion of the pigment list in the near future. If the necessary toxicological testing and the comparison with accepted pigments are made, the fungal pigments, could be acceptable by the current consumer. The potentiality of pigment production in Brazil is possible due to tremendous Amazonian region biodiversity.
