Why do farm workers become more vulnerable as countries get richer? As countries get richer, the share of workers employed in agriculture falls. In richer countries, hired farm workers do ever more of the work on the fewer and larger farms that produce most farm commodities. These hired workers include local workers who lack the skills and contacts needed to get nonfarm jobs that usually offer higher wages and more opportunities as well as legal and unauthorized migrants from poorer countries who may not know or exercise their labor-related rights. Government enforcement of labor laws depends on complaints, and vulnerable workers rarely complain. The Prosperity Paradox explains why farm-worker problems often worsen as the agricultural sector shrinks and lays out options to help vulnerable workers. Analysis of farm labor markets in the US, Mexico, and other countries shows that unions and fair trade efforts to protect farm workers cover a very small share of all workers and are unlikely to expand quickly. Most labor-intensive fruits and vegetables are eaten fresh. Unsafe food that sickened consumers led to voluntary industry and later government-mandated food-safety programs to ensure that food is safe when it leaves the farm, with protocols enforced by both government inspectors and buyers who refused to buy from noncompliant farms. This food-safety model offers the most promise for a new era in protective labor policies.

Food safety testing is of great significance for building a harmonious society. With the advent of the Internet era, the number of data indicators to be considered in food safety testing has gradually increased, and traditional food testing cannot adapt to the fast pace of today’s times. In order to meet the current challenges of food testing, this paper analyses the advantages of “Internet +” in building a food testing laboratory based on the challenges of food safety testing in the Internet era, and discusses the advantages of “Internet +” in the era of food testing. The paper discusses the intelligent working mode of food testing laboratories in the “Internet +” era, and combines big data technology to build an intelligent and comprehensive laboratory management platform, so as to build a new era of food testing intelligent laboratory, which improves the efficiency of food testing managers, reduces the workload, improves the accuracy of food safety testing, and helps the healthy development of the food industry.

Previously, all stereological estimation of particle number and sizes were based on models and notoriously gave biased results, were very inefficient to use and difficult to justify. For all references to old methods and a direct comparison with unbiased methods see recent reviews.The publication in 1984 of the DISECTOR, the first unbiased stereological probe for sampling and counting 3—D objects irrespective of their size and shape, signalled the new era in stereology — and give rise to a number of remarkably simple and efficient techniques based on its distinct property: It is the only known way to obtain an unbiased sample of 3-D objects (cells, organelles, etc). The principle is simple: within a 2-D unbiased frame count or sample only cells which are not hit by a parallel plane at a known, small distance h.The area of the frame and h must be known, which might sometimes in itself be a problem, albeit usually a small one. A more severe problem may arise because these constants are known at the scale of the fixed, embedded and sectioned tissue which is often shrunken considerably.

In the mid-nineteenth century Virchow revolutionized pathology by introduction of the concept of “cellular pathology”. Today, a century later, this term has increasing significance in health and disease. We now are in the beginning of a new era in pathology, one which might well be termed “organelle pathology” or “subcellular pathology”. The impact of lysosomal diseases on clinical medicine exemplifies this role of pathology of organelles in elucidation of disease today.Another aspect of cell organelles of prime importance is their pathologic alteration by drugs, toxins, hormones and malnutrition. The sensitivity of cell organelles to minute alterations in their environment offers an accurate evaluation of the site of action of drugs in the study of both function and toxicity. Examples of mitochondrial lesions include the effect of DDD on the adrenal cortex, riboflavin deficiency on liver cells, elevated blood ammonia on the neuron and some 8-aminoquinolines on myocardium.
