Not all foods are safe to consume, especially during the Covid-19 pandemic. Food stalls one of places meet food needs. The behavior handlers becomes a key safety that is likely be influenced by education, attitudes, level education and training. This study aims determine relationship between knowledge, levels training with stall type design research cross-sectional observations. number samples,...

background: based on genotyping study of human isolates of giardia lamblia ; humans are mainly infected by two assemblages a and b. the present study was carried out to determine the sub-assemblages of g. lamblia isolated from food handlers referred to kashan health centers, central iran, 2015. methods: in this cross-sectional study, 3653 stool samples collected from food-handlers that annually...

Prevalence of asymptomatic norovirus infection was investigated in food handlers in South Korea. Among 6,441 subjects, 66 (1.02%) had norovirus infections confirmed by reverse transcription (RT)-PCR (real time and nested). GII-12 and GII-4 were the prevalent genotypes. Our data suggest that infection of asymptomatic food handlers is an important transmission source in norovirus outbreaks.

BACKGROUND AND OBJECTIVES Hands of ready-to-eat food service employees have been shown to be vectors in the spread of foodborne disease, mainly because of poor personal hygiene and accounting for approximately 97% of food borne illnesses in food service establishments and homes. Our objective was to evaluate the efficacy of hand washing practices and sanitation before commencing work among food...

We present an algebraic treatment of exception handlers and, more generally, introduce handlers for other computational effects representable by an algebraic theory. These include nondeterminism, interactive input/output, concurrency, state, time, and their combinations; in all cases the computation monad is the free-model monad of the theory. Each such handler corresponds to a model of the the...

The study aims at exploring food handlers’ participation on environmentally friendly packaging practices. This research investigates current practices, their environmental awareness level and attitude towards packaging. growing number of usage consumption nonenvironmental has resulted in the deterioration damage our natural environmental. discussed where issue no plastic bag implementation occu...

Effect handlers can be composed by applying them sequentially, each handling some operations and leaving other uninterpreted in the syntax tree. However, semantics of subtle---it is well known that different orders composing lead to drastically semantics. Determining correct order composition a non-trivial task. To alleviate this problem, paper presents systematic way deriving sufficient condit...

We present an effect system for algebraic effects and handlers. Because handlers may transform an effectful computation into a pure one, the effect system is non-monotone in the sense that effects do not just accumulate, but may also be deleted from types or generally transformed. We also provide denotational semantics for the effect system, based on a domain-theoretic model with partial equiva...

The article describes the data mining framework for building a cloud service. The framework can use different distributed execution environments. The article describes the mapping of a data mining algorithm (decomposed into functional blocks) on the set of distributed handlers. These handlers may be implemented as threads, actors and others. In addition, it describes the approach for creation o...
