RESUMEN

Dogs are reservoir hosts of leishmaniasis caused by Leishmania infantum and transmitted by phlebotomine vectors. The effect of dinotefuran, pyriproxyfen and permethrin spot-on solution (Vectra®3D, Ceva Santé Animale, Libourne, France) on Leishmania transmissibility by naturally infected dogs via reared Phlebotomus perniciosus, was assessed. Dogs affected by leishmaniasis were submitted to xenodiagnosis and 6 infecting >10% of insects were treated topically on day 0. Antifeeding, insecticidal and anti-transmissibility effects were evaluated through xenodiagnoses performed on days 1, 7 and 28, using individual pre-treatment parameters as control. Feeding and mortality rates were assessed at 24 h, whereas promastigote infection, maturation and burden were assessed up to 96 h post blood meal (potentially infectious rate). On day 1, the anti-feeding efficacy was >95% in 4 dogs, insecticidal efficacy 100% in 4 dogs, and anti-transmissibility effect 100% in 6 dogs. Efficacy rates recorded on day 7 were very similar to day 1. On day 28, anti-feeding and insecticidal efficacy values were much broader, ranging 32.6-100% and 7.7-94.4%, respectively. Potentially infectious insects were recorded from two dogs, with sharp decrease in transmissibility rate as compared with pre-treatment condition. Altogether, Vectra®3D abrogated by >98% the potential Leishmania transmissibility by the examined pool of infected dogs over 1 month.

RESUMEN

Due to the presence of artefacts in stool samples, the copromicroscopic diagnosis of Ascaris lumbricoides is not always straightforward, particularly in the case of fertilized decorticated eggs. A total of 286 stool samples from 115 schoolchildren in India and 171 adult immigrants in Italy were screened for the presence of A. lumbricoides eggs by both Kato-Katz thick smear and Mini-FLOTAC. If the outer layer of A. lumbricoides eggs was absent, two aliquots of each stool sample were preserved: one for coproculture to identify larvae after development and one to compose a pool of stool for molecular analysis. A total of 64 stool samples (22.4%) were positive for A. lumbricoides using the Kato-Katz thick smear; 36 (56.3%) of these showed mammillated A. lumbricoides eggs, 25 (39.1%) showed elements resembling fertilized decorticated eggs, while three samples (4.7%) showed both mammillated and decorticated eggs. By Mini-FLOTAC, 39 stool samples (13.6%) were positive, while decorticated A. lumbricoides-like eggs were identified as artefacts. These results were confirmed by negative coprocultures and quantitative polymerase chain reaction. Mini-FLOTAC can be used for a reliable diagnosis of A. lumbricoides, thanks to the flotation and translation features which allow a clearer view, resulting in the correct identification of A. lumbricoides eggs.

RESUMEN

Our objective was to measure the efficacy of ivermectin (IVM) and benzimidazoles (BZ, i.e. fenbendazole and albendazole) in 15 cattle farms in western France and southern Italy. A total of 11 groups were treated with IVM and 11 with BZ. Efficacy was assessed by calculating the percentage of faecal egg count reduction (%FECR) using the pre- and post-treatment arithmetic means. Anthelmintic resistance was considered to be present when the %FECR was <95% and the lower limit of the 95% confidence interval <90%. For IVM, the percentages of FECR ranged from 73% to 100%. Lack of efficacy to IVM was detected in two farms out of four in France, but was not detected in any of the seven farms in Italy. For BZ, the percentages of FECR ranged from 95% to 100%. No case of BZ resistance was detected in the five farms in France and the six farms in Italy.

RESUMEN

BACKGROUND AND AIMS: Recently, the albuminocentric view of diabetic kidney disease (DKD) in type 2 diabetes (T2DM) has been changing. Therefore, the relationship between diabetic retinopathy (DR) and chronic kidney disease (CKD) has to be addressed according to this new clinical presentation of DKD. The aim of this study was to evaluate, in a real-world setting, the correlation DR-DKD in T2DM. METHODS AND RESULTS: A total of 2068 type 2 diabetic patients enrolled in a multicenter cross-sectional study were investigated. Albuminuric subjects were largely prevalent among subjects with DR (p = 0.019). In the whole study population, no difference in albumin excretion rate (AER) was observed between presence/absence of DR; instead, AER was significantly higher among patients with glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 (CKD) (p = 0.009), above all in those with CKD and AER ≥0.03 g/24 h (p = 0.005). Multivariate analysis confirmed that eGFR (O.R. 0.976; 95% C.I.: 0.960-1.028; p < 0.001) and AER (O.R. 1.249; 95% C.I. 1.001-1.619; p = 0.004) were independently associated with DR and HDL-cholesterol (O.R.: 1.042; 95% C.I.: 1.011-1.120; p = 0.014). Additionally, among patients with eGFR <60 mL/min/1.73 m2 and albuminuria, both eGFR and AER significantly varied between those with/without DR (p = 0.012 and p = 0.005, respectively), and this finding was observed among only albuminuric patients. Analogous results were obtained considering DR classification. AER was significantly higher among subjects with either proliferative DR (PDR) or severe nonproliferative DR (NPDR), with regard to mild NPDR (0.498 and 0.938 g/die vs. 0.101 g/die; p < 0.001, respectively). Similar results were obtained in the specular subgroups. CONCLUSION: In T2DM with DKD, the AER seems to be related to the presence of DR. This association is confirmed above all in those with more severe DR.

RESUMEN

This study evaluated the long-term efficacy and safety of an 18-month lamivudine prophylaxis in 68 HBsAg-negative/anti-HBc-positive patients with oncohaematological disease. All 68 consecutive HBsAg-negative/anti-HBc-positive patients with an oncohaematological disease and naïve for chemotherapy observed from April 2008 to December 2012 at 2 Hematology Units in Naples were treated with lamivudine for 18 months after stopping chemotherapy and monitored for HBsAg at months 1 and 3 during chemotherapy and then every 3 months after its discontinuation. During follow-up, 13 (19.1%) of the 68 patients died of complications related to their oncohaematological disease, and 3 (4%) showed a virological HBV reactivation (retroconversion to HBsAg positivity) 1-7 months after the discontinuation of lamivudine prophylaxis (2 treated for chronic lymphocytic leukaemia and one for Waldenstrom's disease); of these, 2 showed a biochemical reactivation. Comparing the demographic and clinical characteristics of the 3 patients with a virological HBV reactivation to the 65 without, the former were older (median age and range: 67 years [75-78] vs. 61 [24-88]; P = .05) and were less frequently treated for B-cell non-Hodgkin lymphoma (B-NHL) (0 vs. 70.7%, P = .03). In conclusion, a 18 months of lamivudine prophylaxis was effective in preventing HBV reactivation in HBsAg-negative/anti-HBc-positive patients treated for B-NHL. However, in patients with chronic and severe immunodepression, such as those with chronic lymphocytic leukaemia and Waldenstrom's disease, prophylaxis should be continued for an indefinite period.

RESUMEN

A cross sectional field study on the distribution of Ixodidae ticks was carried out over two consecutive tick seasons (2012 and 2013) in small ruminants (309 farms) located in mainland and five islands of Greece. A total of 2108 ticks (1199 females, 908 males, and 1 nymph) were collected from sheep and goats. Two species of Rhipicephalus, two of Ixodes, five of Hyalomma, three of Haemaphysalis, and one of Dermacentor were detected. The species with the widest distribution were Rhipicephalus sanguineus s.l. (64.8 %), R. bursa (25.9 %), and Dermacentor marginatus (4.1 %), whereas the least frequently collected species were Ixodes ricinus, I. gibbosus, Haemaphysalis parva, H. sulcata, H. punctata, Hyalomma marginatum, H. excavatum, H. dromedarii, H. rufipes, and H. impeltatum representing together less than 5.3 % of the collections. R. sanguineus s.l. was the predominant species, while D. marginatus and I. gibbosus were restricted to the northeastern Aegean Sea islands. This is the first survey on tick fauna from mainland and islands in Greece.

RESUMEN

A double aortic arch is a congenital anomaly associated with the formation of a vascular ring, which can cause varying degrees of airway compression. This can be subclinical or clinical, manifesting as acute stridor, severe respiratory compromise or symptoms of chronic airway compression. An accurate diagnosis of double aortic arch can be made prenatally by fetal echocardiography. In this report, we describe two infants with normal karyotypes in whom a prenatal diagnosis of double aortic arch was made at our fetal cardiology center, between July 2012 and August 2013. The diagnosis was confirmed postnatally by two-dimensional echocardiography and cardiac magnetic resonance imaging (MRI). The presence of a right aortic arch should prompt more careful evaluation to exclude a double aortic arch. Postnatal assessment should comprise echocardiography and cross-sectional imaging in the form of cardiac MRI/computed tomography. Bronchoscopy may be considered to exclude subclinical airway compression and reduce potential long-term respiratory sequelae.

RESUMEN

We carried out the first survey of Hymenolepis spp. infection in pet rodents in Italy. Fresh fecal samples were collected from 172 pet rodents as follows: guinea pigs (Cavia porcellus; n = 60), squirrels (Callosciurus finlaysonii, Callosciurus prevosti, Tamias striatus, Tamias sibiricus, Sciurus calorinensis; n = 52), hamsters (Phodopus campbelli, Mesocricetus auratus; n = 30), chinchillas (Chinchilla lanigera; n = 13), rats (Rattus norvegicus; n = 10), and mice (Mus minutoides; n = 7). These animals were housed either in pet shops or in private houses. All fecal samples were processed using the FLOTAC pellet technique to assess the number of eggs per gram (EPG) of feces. Eggs of Hymenolepis nana were found in 24 out of 172 (13.9 %; 95 % confidence interval = 9.3-20.2 %) pet rodents. Of those rodents, 41.6 % (10/24) were rats (mean EPG = 55.7; range = 2-200), 29.2 % (7/24) mice (mean EPG = 64.5; range = 32-120), 25.0 % (6/24) were chinchillas (mean EPG = 25.5; range = 10-50), and 4.2 % (1/24) hamsters (P. campbelli) (EPG = 86.0). In addition, Hymenolepis diminuta eggs were found in 2 out of 172 (1.2 %; 95 % confidence interval = 0.2-4.6 %) rodents examined, both of which (100 %; 2/2) were pet squirrels (C. prevosti) (mean EPG = 10; range = 4-16). To the authors' knowledge, this is the first report of a natural infection of H. diminuta in pet squirrels.

RESUMEN

BACKGROUND: Recently, an increased scientific interest was focused on mild approaches for ovarian stimulation in clinical practice. Milder stimulation aims to develop safer and more patient-friendly protocols which are more physiological, less drug use, less expensive and the risks of treatment are highly minimized. AIM: To investigate the efficacy and safety of a mild ovarian stimulation protocol in patients at high risk of developing ovarian hyperstimulation syndrome (OHSS), compared to conventional long down-regulation protocol. SUBJECTS AND METHODS: This a prospective, open, randomized study, included 349 infertile patients considered at high risk of developing OHSS, undergoing in vitro fertilization treatment in two private assisted reproduction centers. The patients were randomized into two groups: group A (n = 148) had a mild/minimal stimulation protocol of recombinant FSH (rFSH) combined with GnRH antagonist. Group B (n = 201) (control group) had a standard long protocol of rFSH combined with GnRH agonist. RESULTS: There was no significant difference observed between the two groups regarding the mean number of oocytes retrieved per patient, mature metaphase II oocytes, fertilization rate, and embryo cleavage rate. Significantly higher implantation rate (21.5 vs 14.5 %) (p < 0.05), pregnancy rate (37.7 vs 23.4 %) (p < 0.05), and delivery rate (32.8 vs 20.1 %) (p < 0.05) were observed in favor of groups A compared to group B. Lower proportion of patients (4.7 %), though not statistically significant, has developed OHSS in group A compared to group B (8.4 %). CONCLUSION: Our study shows that mild stimulation regimen is highly effective for ovarian stimulation of patients who have experienced OHSS complication without increasing the risk of OHSS.

RESUMEN

The Protein Data Bank in Europe (PDBe; pdbe.org) is a partner in the Worldwide PDB organization (wwPDB; wwpdb.org) and as such actively involved in managing the single global archive of biomacromolecular structure data, the PDB. In addition, PDBe develops tools, services and resources to make structure-related data more accessible to the biomedical community. Here we describe recently developed, extended or improved services, including an animated structure-presentation widget (PDBportfolio), a widget to graphically display the coverage of any UniProt sequence in the PDB (UniPDB), chemistry- and taxonomy-based PDB-archive browsers (PDBeXplore), and a tool for interactive visualization of NMR structures, corresponding experimental data as well as validation and analysis results (Vivaldi).

RESUMEN

AIM: Psoriasis is a multifactorial chronic inflammatory skin disease that often occurs in patients who are overweight or obese. In literature the connections between obesity and eating disorders are well known, but few studies have investigated the link between eating disorders and psoriasis. We hypothesized that Eating Disorders (ED) can be considered a psychogenic cofactors, which contribute to the development of obesity and metabolic syndrome in psoriatic patients, who are frequently prone to psychiatric comorbidity. METHODS: From January to April 2011 we enrolled 100 consecutive psoriatic outpatients and a control group of 100 selected non-psoriatic outpatients, matched by age, gender, and BMI to the study group. The assessment battery was composed by the Psoriasis Area Severity Index (PASI) score, the Eating Disorder Inventory (EDI) and the Symptom Checklist-90 Revised (SCL-90-R®). RESULTS: Our data showed that most of EDI and SCL-90R subscales was mostly altered in psoriatic population compared to patients without psoriasis. Moreover, we noticed in patients with psoriasis an association between the progressive weight increase and an impairment on most of EDI subscales. CONCLUSION: Psoriasis is associated with psychopathological traits, which are frequently found in EDs. Since obesity makes psoriasis less susceptible to therapy and weight loss improves drug response, dermatologists should be alert to suspect the presence of this condition.

RESUMEN

BACKGROUND: The severe acute respiratory syndrome Coronarovirus-2 associated still causes a significant number of deaths and hospitalizations mainly by the development of respiratory failure. We aim to validate lung ultrasound score in order to predict mortality and the severity of the clinical course related to the need of respiratory support. METHODS: In this prospective multicenter hospital-based cohort study, all adult patients with diagnosis of SARS-CoV-2 infection, performed by real-time reverse transcription polymerase chain reaction were included. Upon admission, all patients underwent blood gas analysis and lung ultrasound by expert operators. The acquisition of ultrasound scan was performed on 12 peculiar anatomic landmarks of the chest. Lung ultrasound findings were classified according to a scoring method, ranging 0 to 3: Score 0: normal A-lines. Score 1: multiple separated B-lines. Score 2: coalescent B-lines, alteration of pleural line. Score 3: consolidation area. RESULTS: One thousand and seven patients were included in statistical analysis (male 62.4 %, mean age 66.3). Oxygen support was needed in 811 (80.5 %) patients. The median ultrasound score was 24 and the risk of having more invasive respiratory support increased in relation to higher values score computed. Lung ultrasound score showed negative strong correlation (rho: -0.71) with the P/F ratio and a significant association with in-hospital mortality (OR 1.11, 95 %CI 1.07-1.14; p < 0.001), even after adjustment with the following variables (age, sex, P/F ratio, SpO2, lactate, hypertension, chronic renal failure, diabetes, and obesity). CONCLUSIONS: The novelty of this research corroborates and validates the 12-field lung ultrasound score as tool for predicting mortality and severity clinical course in COVID-19 patients. Baseline lung ultrasound score was associated with in-hospital mortality and requirement of intensive respiratory support and predict the risk of IOT among COVID-19 patients.

RESUMEN

Selective per-substituted cyclodextrin design enables the carrier's physicochemical and binding properties to be tailored and can even modify some biological native structure effects. We herein report a number of highly efficient microwave-assisted synthetic protocols for the preparation of several amino, ureido and thioureido per-substituted ß-cyclodextrin derivatives. A rapid parallel synthetic approach has given a set of 14 different CD derivatives. Our strategy is supported by computational analyses which were used to estimate the physicochemical behaviour of per-substituted derivatives and to tailor suitable substituents.

RESUMEN

BACKGROUND: Ovarian stimulation is an integral procedure in assisted reproduction treatment. It is achieved by the administration of exogenous gonadotropins to increase follicular recruitment and oocyte yield. Optimization of ovarian stimulation is an essential prerequisite for the success of IVF treatment. AIM: This study aimed to evaluate the effect of a combined stimulation protocol of human FSH and recombinant FSH, simultaneously administered, on oocyte and embryo quality and clinical outcome. PATIENTS AND METHODS: In a prospective randomized study 197 infertile patients with a history of previous IVF failures for at least 3-5 attempts, were enrolled for an in vitro fertilization treatment. All patients had a standard down-regulation with GnRH analog and were then stimulated with FSH. The patients were matched into three groups: group A (no = 66) received human FSH combined with recombinant FSH in equal doses, simultaneously administered; group B (no = 67) received human FSH alone and group C (no = 64) received recombinant FSH alone. RESULTS: There were significantly higher pregnancy (p < 0.04) and implantation rates (p < 0.03) in favor of group A (hFSH/rFSH) compared to groups B (hFSH) and C (rFSH). A significant increase in the proportion of mature metaphase II oocytes (p < 0.002) and grade 1 embryos (p < 0.03) was observed in group A with respect to group B and C. Significantly higher delivery rate (p < 0.01) was achieved in group A compared to groups B and C. No significant differences were observed between groups regarding miscarriage rate and risk of ovarian hyperstimulation syndrome. CONCLUSIONS: The results show that the combination of human and recombinant FSH for ovarian stimulation may produce a positive effect on follicular development as it improve oocyte quality, embryo development, and ultimately clinical outcome.

RESUMEN

Misophonia is an unusually strong aversion to everyday sounds such as chewing, crunching, or breathing. Previous studies have suggested that rates of autism might be elevated in misophonia, and here we examine this claim in detail. We present a comprehensive review of the relevant literature, and two empirical studies examining children and adults with misophonia. We tested 142 children and 379 adults for traits associated with autism (i.e., attention-to-detail, attention-switching, social processing, communication, imagination, emotion regulation, and sensory sensitivity across multiple domains). Our data show that autistic traits are indeed elevated in misophonics compared to controls. We discuss our findings in relation to models of the interface between autism, sensory sensitivities, and the specific features of misophonia.

RESUMEN

Reptiles have increased in popularity worldwide; snakes and lizards are frequently used as pets. As a consequence of their popularity, the interest of the scientific community in these animals has increased. In order to acquire epidemiological data on the parasitic infections affecting reptiles in Italy a survey was carried out in 125 snakes and 25 lizards bred in the Campania region of southern Italy. Individual fecal samples were collected and FLOTAC was used for copromicroscopic diagnosis. Eimeriidae, oxyurids, strongylids, other gastro-intestinal nematodes and pulmonary nematodes were the most representative parasites found. Eggs of pseudoparasites (mites, oxyurids and trichurids affecting rodents) were also found. The use of FLOTAC for diagnosis of parasitic infections in reptiles has demonstrated to be a rapid and sensitive test to improve diagnosis and acquire new information on the parasitological fauna of reptiles.

RESUMEN

In order to acquire prevalence and genetic data on Cryptosporidium infections in captive lizards and snakes kept as pets, a survey was conducted on 150 individual reptiles from southern Italy. Fecal samples were preserved in 5% formalin and analyzed using a commercial immunofluorescence assay (IFA) for the detection of Cryptosporidium oocysts and Giardia cysts. IFA revealed the presence of Cryptosporidium oocysts in nine of the 150 samples examined (6.0%), precisely in 6/125 snakes (4.8%) and in 3/25 lizards (12.0%); all fecal samples tested negative for the presence of Giardia cysts. Molecular characterization based on nested PCR amplification and sequencing of the SSU-rRNA gene, revealed the presence of Cryptosporidium serpentis in three samples from snakes (Boa constrictor constrictor, Elapheguttata guttata guttata and Python molurus).

RESUMEN

INTRODUCTION: A 5-year retrospective analysis of ascarid infections (Toxocara canis and Toxascaris leonina) in dogs from southern Italy was performed to update the epidemiological scenario of these parasites and to identify the risk factors which may favour these infections in animals in this study area. A total of 8,149 dogs, referred to our labs for copromicroscopic analysis using the FLOTAC technique, was considered. A sub-sample of 500 faecal samples were analysed also with the Mini-FLOTAC technique. Of the overall dog samples analysed, 9,2 % (95 % CI = 8,6-9,8) resulted positive for T. canis while 0,5 % (95 % CI = 0,4-0,7) resulted positive for T. leonina. Co-infections with T. canis and T. leonina were found in 0,1 % of dogs (95 % CI = 0,0-0,1). The results obtained by the FLOTAC and Mini-FLOTAC examinations showed a nearly perfect k agreement (k = 0,99, P < 0,001) between these two techniques. Chi-square test showed positivity to T. canis and T. leonina significantly (P < 0,001) associated with dogs housed outdoor (i.e., that lived in garden or in kennel). Moreover, the positivity for T. canis was significantly associated (P < 0,001) also with age (i.e., puppies), as shown by the logistic regression. The decreasing overall prevalence both for T. canis and T. leonina during the years of monitoring, showed that, as suggested by the European Scientific Counsel Companion Animal Parasites, the regular diagnosis could contribute to an efficient control of these parasites.


INTRODUCTION: Une analyse rétrospective sur 5 ans des infections à ascaris (Toxocara canis et Toxascaris leonina) chez les chiens du sud de l'Italie a été réalisée afin de mettre à jour le scénario épidémiologique de ces parasites et d'identifier les facteurs de risque pouvant favoriser ces infections chez les animaux de cette zone d'étude. Au total, 8149 chiens ont été analysés dans notre laboratoire avec une analyse copromicroscopique en utilisant la technique FLOTAC. De plus, un sous-échantillon de 500 échantillons fécaux a été analysé avec la technique Mini-FLOTAC. Sur l'ensemble des échantillons fécaux canins analysés, 9,2 % (IC à 95 % = 8,6 à 9,8) se sont révélés positifs pour T. canis tandis que 0,5 % (IC à 95 % = 0,4 à 0,7) ont été positifs pour T. leonina. Des co-infections avec T. canis et T. leonina ont été trouvées chez 0,1 % des chiens (IC à 95 % = 0,0­0,1). Les résultats obtenus par les examens FLOTAC et Mini-FLOTAC ont montré un coefficient Kappa presque parfait (k = 0,99, p < 0,001) entre ces deux techniques. Le test du chi carré a montré une positivité significative quant aux infections à T. canis et T. leonina (P < 0,001) associées à des chiens hébergés à l'extérieur (jardin ou chenil). De plus, la positivité pour T. canis était également significativement associée (P < 0,001) à l'âge (c'est-à-dire aux chiots), comme le montre la régression logistique. La diminution de la prévalence globale au cours de la période de surveillance a montré que le diagnostic régulier pourrait contribuer à un contrôle efficace de ces parasites à la fois pour T. canis et T. leonina, comme suggéré par le the European Scientific Counsel Companion Animal Parasites.

RESUMEN

Ready-to-eat (RTE) salads and berries are increasingly consumed in industrialized countries. These products can be contaminated by pathogenic parasites that have been responsible for foodborne outbreaks worldwide. In Italy, there are few data on contamination of RTE salads and berries with parasite transmission stages and this requires more-in-depth investigations. To estimate the prevalence of contamination with Cryptosporidium spp. and Giardia duodenalis in these fresh products, a total of 324 packages of local RTE mixed salads - belonging to three different industrial brands - and 324 packages of berries - blueberries from Peru, blackberries from Mexico, raspberries from Italy - were bought from supermarkets located in the Provinces of Bari and Foggia, Apulia, Italy. A pool size of nine packages was chosen and a total of 72 pools were processed in the whole year. After washing, the pellets were examined by microscopy (FLOTAC) and tested using conventional simplex PCR, targeting Cryptosporidium spp., Giardia duodenalis, and Entamoeba spp., and sequencing. Several Cryptosporidium species and Giardia duodenalis assemblages, some of which are of potential zoonotic relevance, as well as Entamoeba spp., were identified in both matrices. By microscopy, Giardia-like cysts in local raspberries and Entamoeba-like cysts in imported blueberries were detected. Giardia duodenalis (Assemblages A, B and E) and Entamoeba histolytica were molecularly confirmed with overall prevalences of 4.6% (95% C.I. 3.0-6.8) and 1% (95% C.I. 0.3-2.1), respectively. Molecular methods identified Cryptosporidium ryanae, Cryptosporidium bovis, Cryptosporidium xiaoi, and Cryptosporidium ubiquitum in both matrices, with a prevalence of 5.1% (95% C.I. 3.3-7.3). A distinct seasonality in prevalence was observed for G. duodenalis, with most positives occurring in spring, whereas Cryptosporidium showed no significant seasonal variations. These results highlight that inadequate management of fresh produce, both locally produced and imported, along the food chain may have the potential for consequences on human health.
