Sexual and gender minority (SGM) and racial or ethnic minority youth at-risk for or living with HIV may have higher risk of SARS-CoV-2 infection. However, there are few data on vaccine hesitancy/acceptance and COVID-19 self-protective behaviors among this population. Youth aged 15-24 years (n = 440), predominantly African American and Latine (73%, n = 320) SGM, from Los Angeles and New Orleans reported their vaccine attitudes and COVID-19 and HIV preventive behaviors in October 2020. Latent class analyses categorized individuals into groups based on their vaccine attitudes and preventive behaviors. Relationships between these groups and other factors were analyzed using Fisher's exact tests, ANOVA, and logistic regression. Most youth had accepting vaccine attitudes (70.2%, n = 309), with 20.7% hesitant (n = 91), and 9.1% resistant (n = 40). SGM and African Americans were significantly less accepting than their cis-gender and heterosexual peers. About two-thirds (63.2%, n = 278) of the respondents reported consistent COVID-19 self-protective behaviors. Youth with pro-vaccine attitudes were most consistently self-protective; however, only 54.4% (n= 168/309) intended to take a COVID-19 vaccine. Homelessness history, race, and sexual orientation were associated with vaccine attitudes. Accepting vaccine attitudes and consistent COVID-19 self-protective behaviors were closely related. COVID-19 attitudes/behaviors were not associated with HIV risk and only loosely associated with SARS-CoV-2 vaccine intentions.

Quantitative Biology - Populations and Evolution - Abstract
The consumption rate is a process critically important for the stability of consumer-resource systems and the persistence, sustainability and biodiversity of complex food webs. Its mathematical description in the form of functional response equations is a key problem for describing all trophic interactions. Because some of the functional response models used in this study presented redundancy between its parameters two methods were used to check for parameter redundancy: the Hessian matrix calculation using automatic differentiation (AD) which calculates derivatives numerically, but does not use finite differences, and the symbolic method that calculates a derivative matrix and its rank. In this work, we found that the models that better describe the functional response of a rotifer is consumer dependant even at low consumer densities, but their parameters can not be estimated simultaneously because parameter redundancy. This means that fewer parameters or parameter combination can be estimated than the original number of parameters in the models. Here, the model parameters that incorporate intraspecific competition by interference in the consumer-resource interaction are not identifiable, suggesting that this problem may be more widespread than is generally appreciated in the literature of food webs. Including knowledge on competitive interactions in current model predictions will be a necessity in the next years for ecology as ecological models are getting more complex and more real. Identifiability of biological parameters in nonlinear ecological models will be an issue to consider.

BackgroundOver 20% of HIV diagnoses in the United States are among youth aged 12-24 years. Furthermore, youth have the lowest rates of uptake and adherence to antiretroviral (ARV) medications and are least aware of their HIV status.ObjectiveOur objective was to design a set of interrelated studies to promote completion of each step of the HIV Prevention Continuum by uninfected youth at high risk (YHR), as well as completion of steps in the Treatment Continuum by youth living with HIV (YLH).MethodsGay, bisexual, and transgender youth; homeless youth; substance-abusing youth; youth with criminal justice contact; and youth with significant mental health challenges, particularly black and Latino individuals, are being recruited from 13 community-based organizations, clinics, drop-in centers, and shelters in Los Angeles and New Orleans. Youth are screened on the basis of self-reports and rapid diagnostic tests for HIV, drug use, and sexually transmitted infections and, then, triaged into one of 3 studies: (1) an observational cohort of YLH who have never received ARV medications and are then treated-half initially are in the acute infection period (n=36) and half with established HIV infection (n=36); (2) a randomized controlled trial (RCT) for YLH (N=220); and (3) an RCT for YHR (N=1340). Each study contrasts efficacy and costs of 3 interventions: an automated messaging and weekly monitoring program delivered via text messages (short message service, SMS); a peer support intervention delivered via social media forums; and coaching, delivered via text message (SMS), phone, and in-person or telehealth contacts. The primary outcomes are assessing youths' uptake and retention of and adherence to the HIV Prevention or Treatment Continua.

Black men who have sex with men and women (BMSMW) are at increased HIV risk, but few efficacious interventions meet their unique needs. Three HIV prevention interventions were evaluated with a common protocol. Baseline data were pooled to describe sexual behavior involving transmission risk with male, female, and male-to-female transgender partners and identify factors associated with transmission risk. BMSMW from Los Angeles, Philadelphia, and Chicago who reported sexual risk and bisexual behavior in the past year were recruited via modified chain referral sampling and community recruitment. Baseline assessments were conducted via audio computer-assisted interview and sexual behaviors assessed over the past 3 months. From December 2010 to November 2012, 584 BMSMW were enrolled across the three cities. More than half (55%) were recruited by other participants. Overall, the mean age was 43 years. Seventy-five percent reported an annual income

Nieto Fernández, María Isabel and Nieto Fernández, María Isabel
- Abstract
The Global Security Strategy launched in June 2016 by the High Representative of the Union for Foreign Affairs and Security, Federica Mogherini, is key to addressing global pressures in a world undergoing continuous transformation and change and in which this 27-member state political system strives not only to adapt but also to play a more decisive role, now and in the future, on the global agenda. This book aims to introduce readers to the theory and practice of the EU's External Action, which is based on the principles and values that guide it and that it aims to promote throughout the world: democracy, rule of law, human rights and fundamental freedoms, solidarity, respect for the principles of the United Nations Charter and International Law. And, specifically, it aims to introduce readers to the intricacies of EU policy and its role in the Mediterranean, bringing them closer to a comprehensive analysis of the links between the Union and its southern neighbours, with a special focus on the European Neighbourhood Policy and the impact of energy supply and the environment on security and defence. The reflections presented here aim, through the dissemination of the results of the main activities of the Jean Monnet Module “ThEUMed”, to draw the attention of EU policymakers on the southern border of the Union in order to strengthen common understanding between its Member States on the issues of the South and with the southern and eastern Mediterranean countries to address new challenges in the fields of cooperation and international security and defence in the region. Thus, they include the observations of the main members of the academic team of the project and two course graduates. We hope not to leave readers indifferent and that they enjoy reading this volume.

- Abstract
La Estrategia Global de Seguridad lanzada en 2016 por la Alta Representante de la Unión para Asuntos Exteriores y de Seguridad, Federica Mogherini es clave para hacer frente a las presiones globales en un mundo en continua transformación y cambio y en el que este sistema político a 27 trata no solo de adaptarse sino también de desempeñar un rol más decisivo, en el presente y en el futuro, en la agenda global. Este libro pretende introducir a los lectores en la teoría y práctica de la Acción Exterior de la UE que se sustenta en los principios y valores que la guían y que trata de fomentar en todo el mundo: la democracia, el estado de derecho, los derechos humanos y las libertades fundamentales, la solidaridad, el respeto de los principios de la Carta de Naciones Unidas y del Derecho Internacional. Y, en concreto, pretende introducir a los lectores en los entresijos de la política de la UE y su papel en el Mediterráneo, acercándoles a un análisis global de los vínculos entre la Unión y los países vecinos del sur, con un enfoque especial en la política europea de vecindad y el impacto del suministro de energía y el medio ambiente en la seguridad y la defensa. Estas reflexiones que ahora se presentan ambiciona, a través de la difusión de los resultados de las principales actividades del Módulo Jean Monnet “ThEUMed”, llamar la atención de los responsables políticos de la UE sobre la frontera sur de la Unión, promoviendo el fortalecimiento de un común entendimiento entre sus Estados miembros sobre las cuestiones del sur y con los países del Sur y Este del Mediterráneo, haciendo frente a los nuevos desafíos comunes en los campos de cooperación y seguridad internacional y defensa en el área. Se recogen pues las observaciones de los principales miembros del equipo académico del proyecto y de dos de los diplomados en el curso. Deseamos no dejar indiferentes a los lectores y que disfruten de la lectura de este volumen.

alimentación ,zootecnia ,genética - Abstract
El Gochu Asturcelta es una raza porcina autóctona de Asturias en extremo riesgo. Tradicionalmente se asume que la raza pertenece al tronco porcino celta de la península ibérica al igual que la raza de cerdo Celta de Galicia o la raza Bísara de Portugal. El Gochu Asturcelta prácticamente se extinguió en la segunda mitad del siglo XX. En 2002 se fundó la asociación de criadores ACGA que, con seis fundadores, inició un programa de conservación con el apoyo del Gobierno del Principado de Asturias. El objetivo de la presente Memoria es documentar la raza de Gochu Asturcelta mediante la caracterización de su variabilidad genética y de sus relaciones genéticas con las poblaciones porcinas más importantes de su entorno geográfico. Para cumplir con ese objetivo se han aplicado diversas metodologías para: a) evaluar el efecto de la política de apareamientos recomendada por ACGA para el mantenimiento de la variabilidad genética de la raza; b) conocer si la asignación del Gochu Asturcelta al grupo de cerdos de estirpe celta de la península ibérica tiene respaldo genético; y c) estimar el tamaño efectivo de la raza de Gochu Asturcelta para predecir su viabilidad.En un primer trabajo (Menéndez et al. 2015) se desarrolló una batería de 20 microsatélites para llevar a cabo pruebas de paternidad en el marco del programa de conservación. Esta batería de marcadores se aplicó a 19 lechones producidos por tres cerdas diferentes, cada una de las cuales se habían mantenido, accidentalmente, sin restricciones para el apareamiento con dos verracos diferentes. En dos de los casos los verracos eran hermanos completos de las cerdas madres. En el tercer caso, uno de los verracos era hermano completo de la cerda. La batería de microsatélites permitió asignar los lechones a uno de los verracos candidatos con confianza estadística alta. Todas las camadas testadas tuvieron dos padres diferentes. Los apareamientos accidentales analizados ocurrieron en un momento muy inicial del programa de cría poniendo en riesgo la calidad de las genealogías recogidas en el Libro Genealógico de ACGA. Se recomendaron estrictas pautas de manejo y apareamientos para evitar nuevos apareamientos no supervisados entre parientes cercanos.Un Segundo trabajo (Menéndez et al. 2016a) analizó la información registrada en el Libro Genealógico de la raza de Gochu Asturcelta desde su fundación hasta agosto de 2014 para determinar si la política de apareamientos llevada a cabo por ACGA ha tenido éxito en preservar la representación de los fundadores en la población presente. La consanguinidad media del pedigrí fue muy alta (0,230 ± 0,078). Sin embargo la tasa de incremento individual en consanguinidad se ha mantenido estable, alrededor de 0,07, desde 2009. Se han registrado notables pérdidas de variabilidad genética por deriva. El parámetro equivalente a genomas fundadores (fg), que caracteriza las pérdidas de variabilidad genética debidas a cualquier causa de deriva, fue de, aproximadamente, el 60% del valor de tamaño efectivo de fundadores (fe), que caracteriza las pérdidas de variabilidad genética debidas a contribuciones desequilibradas de los fundadores. Sin embargo, el cociente entre el número efectivo de ancestros (fa) y fe fue de, aproximadamente, 1. Este hecho sugiere que la política de apareamientos de ACGA ha permitido evitar la aparición de un cuello de botella en la población resultante del uso abusivo de un número reducido de reproductores. Se pudo constatar la necesidad de desequilibrar las contribuciones genéticas para las siguientes generaciones a favor de una línea fundadores poco representada.En un tercer trabajo (Menéndez et al. 2016b) la variabilidad genética del Gochu Asturcelta se evaluó mediante marcadores moleculares para conocer las relaciones genéticas de la raza con otras de importancia en su entorno geográfico y para determinar si la clasificación tradicional del cerdo autóctono de la península ibérica en estirpes celta e ibérica tiene concordancia con diferencias genéticas entre marcadores neutros. Dos poblaciones de Gochu Asturcelta (inicial y presente) se genotiparon con 17 marcadores de tipo microsatellite para tener en cuenta la posible deriva acumulada desde el inicio del programa de cría de la raza. Las dos poblaciones de Gochu Asturcelta se compararon con cuatro poblaciones de cerdos domésticos, que incluían individuos de ocho razas diferentes, y jabalí. La diferenciación entre las dos poblaciones de Gochu Asturcelta fue muy baja (FST = 0.021 ± 0.005). El parámetro equivalente a genomas fundadores, calculado a partir de información molecular, tomó prácticamente el mismo valor para las dos poblaciones de Gochu Asturcelta, lo que sugiere que la raza no ha experimentado pérdidas de variabilidad genética importantes desde la puesta en marcha del programa de cría. En todo caso, las dos poblaciones de Gochu Asturcelta mostraron una notable diferenciación genética respecto de las otras poblaciones disponibles, probablemente debido a la gran identidad genética de los animales de Gochu Asturcelta genotipados. Por otra parte se secuenció un fragmento de 647 pares de bases de la región de control del ADN mitocondrial en 174 individuos de las mismas poblaciones. De los 30 haplotipos identificados, el Gochu Asturcelta solo presentó tres. Las familias haplotípicas A (más frecuente en cerdo centroeuropeo) y C (más frecuente en cerdo ibérico y jabalí ibérico y del norte de África) estuvieron presentes tanto en cerdos de estirpe celta como en la estirpe ibérica y en razas de cerdos cosmopolitas. La composición de ADN mitocondrial de la península ibérica refleja la historia reciente de las poblaciones analizadas más que su composición ancestral. Este hecho hace difícil apoyar la división tradicional del cerdo de la península ibérica en estirpes celta e ibérica mediante el polimorfismo de marcadores moleculares neutros.Un cuarto trabajo (Menéndez et al. 2016c) profundizó en la estimación del tamaño efectivo (Ne) de la población de Gochu Asturcelta. Se aplicaron diversas metodologías para estimar Ne mediante información molecular y se compararon sus resultados con estimas genealógicas. Se utilizaron genotipos de 17 marcadores microsatélites obtenidos en 780 individuos de raza Gochu Asturcelta que se asignaron a dos generaciones filiales discretas (F3 y F4) y cinco cohortes anuales (desde 2006 a 2010) con solapamiento generacional. Cualquiera que fuera el método utilizado, las estimas moleculares de Ne fueron mayores que las genealógicas. Estimas de Ne calculadas mediante el desequilibrio de ligamiento de una sola muestra de la población (Ne(LD)) en F3 y F4 fueron más estables y menores que las calculadas para cohortes anuales o bianuales. Las estimas de Ne(LD) calculadas sobre muestras con solapamiento generacional solo fueron comparables con las obtenidas para las generaciones discretas cuando el periodo de muestreo era similar al intervalo generacional y se efectuaron correcciones para evitar el sesgo demográfico. Estimas de Ne calculadas mediante coascendencia molecular en una sola muestra de la población (Ne(M)) no fueron independientes de las estimas correspondientes de Ne(LD) debido a que tanto el desequilibrio de ligamiento como la coascendencia molecular tendieron a covariar. En todo caso, los valores de las estimas de Ne(M) fueron menores que los correspondientes de Ne(LD) debido a que reflejan en mayor medida el número de genomas fundadores que el tamaño efectivo de la población. La estimas de Ne obtenidas mediante métodos temporales (dos muestras) fueron muy dependientes del intervalo entre muestras e inaceptablemente sesgadas hacia arriba antes de realizar correcciones por sesgo demográfico. En conjunto, la evidencia empírica obtenida sugiere que las estimas moleculares de Ne deben interpretarse cuidadosamente en muestras con generaciones solapadas. Esas estimas pueden ser útiles cuando se dan las siguientes condiciones: a) el tamaño muestral es suficiente y representativo de la estructura genética y relaciones de parentesco de la población; b) se aplica corrección por sesgo demográfico; y c) el intervalo utilizado para la definición de la cohorte a genotipar no es arbitrario y se corresponde con la demografía y estructura genética de la población. Esas restricciones hacen que los métodos basados en la toma de una sola muestra no tengan una gran ventaja operativa.La particular estructura de la población de Gochu Asturcelta, con presencia de generaciones discretas y solapadas en su pedigrí, la convierte en un escenario único para el desarrollo de futuros estudios tendentes a establecer la relación entre autocigosis (homocigosis debida identidad por descendencia) e identidad por estado.

Nominal rewriting generalises first-order rewriting by providing support forthe specification of binding operators. In this paper, we give sufficient conditions for (local) confluence of closed nominal rewriting theories, based on the analysis of rule overlaps. More precisely, we show thatclosed nominal rewriting rules where all proper critical pairs are joinable are locally confluent. We also show how to refine the notion of rule overlap to derive confluence of the closed rewriting relation. The conditions that we define are easy to check using a nominal unification algorithm.

TheoryofComputation_MATHEMATICALLOGICANDFORMALLANGUAGES ,TheoryofComputation_LOGICSANDMEANINGSOFPROGRAMS - Abstract
Nominal systems are an alternative approach for the treatment of variables in computational systems. In the nominal approach variable bindings are represented using techniques that are close to first-order logical techniques, instead of using a higher-order metalanguage. Functional nominal computation can be modelled through em nominal rewriting, in which alpha-equivalence, nominal matching and nominal unification play an important role. Nominal unification was initially studied by Urban, Pitts and Gabbay and then formalised by Urban in the proof assistant Isabelle/HOL and by Kumar and Norrish in HOL4. In this work, we present a new specification of nominal unification in the language of PVS and a formalisation of its completeness. This formalisation is based on a natural notion of nominal alpha-equivalence, avoiding in this way the use of the intermediate auxiliary weak alpha-relation considered in previous formalisations. Also, in our specification, instead of applying simplification rules to unification and freshness constraints, we recursively build solutions for the original problem through a straightforward functional specification, obtaining a formalisation that is closer to algorithmic implementations. This is possible by the independence of freshness contexts guaranteed by a series of technical lemmas.

- Abstract
Blast is the main wheat disease in Bolivia and to tackle it we are applying a breeding strategy, which has proven its efficacy for obtaining rice varieties with a high level of durable partial resistance to blast. Incomplete information is available on wheat blast resistance, so, firstly we base our strategy on the worst hypotheses. Next, the possible invalidation of every hypothesis can allow simplifying the breeding schema and its implementation. These successive or complementary hypotheses are the following: H01: The obtaining of a sufficient resistance is impossible; H02: Only a partial resistance with a low level is available; H03: The partial resistance is polygenic; H04: The partial resistance is little heritable; H05: The partial resistance is partly specific; H06 and H07: A complete resistance is obtained and is specific; H08: The disease resistance penalizes the yield. For every hypothesis, the consequences of its consideration, the study of its validity and the consequences of its possible invalidation are explained. Scientific arguments, references, and materials and methods details are provided. Briefly, these hypotheses lead 1) to the obtaining and to the cheapest multiplication of genetically pure blast-free seeds for blast-free cropping areas, 2) to the search of new resistance genes or new genetic backgrounds for the expression of such genes in core collections and in recurrent populations with a very broad genetic base, and 3) to the implementation of the participatory recurrent selection in populations with a narrow genetic base with the extraction of lines for providing the participatory creation of varieties. Every sub‑program, i.e., for obtaining new varieties for a specific set of agro‑ecological, socio-economical, industrial and commercial conditions and purposes, needs less than 1.000 m2. This own strategy is focused on the obtaining of adequate resistant varieties as fast as possible in the respect for the Bolivian scientific sovereignty, by a complementary approach of those of the other teams and by an application of the subsidiarity principle.

- Abstract
[EN] The use of veterinary drugs to treat mastitis and other pathologies in dairy sheep and goats is a usualpractice in current production systems. The risk of antibiotic residues in milk on farms is high if goodfarming practices are not applied, in this sense control measures must be implemented to prevent drugresidues from entering the food chain. Moreover there are other compounds that may contaminate milkvia the environment, water or animal feed, such as mycotoxins that are one of the most harmful contam-inants given their negative effects on consumer health. This work presents the problems that arise whenresidues and contaminants are present in sheep and goat s milk. It also addresses the causes and theconsequences of their presence, and the main measures of prevention and control required to guaranteemilk that is safe for consumers and of high quality for the dairy industry.

- Abstract
[EN] The detection capability (CC beta) of some microbial screening tests currently available was calculated for sheep and goat milk in accordance with Commission Decision 657/2002/EC. The CC beta was at or below the maximum residue limit (MRL) for most beta-lactams assessed and other non-beta-lactam drugs such as neomycin, tylosin, sulfadiazine and sulfadimethoxine. However, the tests were less sensitive in the detection of most non-beta-lactam drugs such as quinolones and tetracyclines at safety levels. When individual sheep milk samples free of antibiotics were analysed, an elevated somatic cell count was related to the occurrence of non-compliant results in all the methods assessed. To guarantee the safety of milk and dairy products from small ruminants, the periodical implementation of screening tests more sensitive towards non-beta-lactam drugs would be appropriate.

- Abstract
Given their broad spectrum, cephalosporins are used for combating mastitis in dairy species. Many cephalosporins, such as cephalexin, have not been authorized for use in lactating sheep and because veterinary drugs for use in small species are lacking, the regulations of several countries allow extra-label use. Incorrect use of extra-label tools may cause residues in milk, and could negatively affect public health by provoking technological failures in the dairy fermenting processes. The effects of cephalexin, at concentrations close to its European Maximal Residue Limit (MRL), have been studied in set-type yogurts made from sheep s milk. Milk was fortified at different cephalexin concentrations and stored yogurts were evaluated in acidification, textural parameters and microbial evolution terms. The results showed that cephalexin concentrations equal to or below its MRL could mainly inhibit normal Streptococcus thermophilus growth and provoke some alterations to acidity parameters, which were more marked in the L(+)-lactic acid isomer.

Spanish legislation establishes the control of the presence of antibiotic residues in sheep and goat s milk using screening methods that detect, at least, beta-lactam drugs. Microbial inhibitor tests using Geobacillus stearothermophilus var. calidolactis and specific receptor-binding assays are most widely employed for this purpose. The detection rates of screening tests routinely used in Spain have been calculated considering the frequency of use of veterinary drugs commonly applied in ovine and caprine livestock to treat and prevent mastitis as well as the test sensitivity toward these substances at safety levels. In general, the use of a single test allows detecting 62.8-82.4% of the antibiotics employed. For sheep milk, the total detection range achieved with microbial tests was significantly higher than that reached with rapid receptor tests. However, no significant differences between the two types of methods were found when goat s milk was analysed. In both types of milk, the simultaneous use of two screening tests with a different analytical basis increases the total detection range significantly,reaching values ≥ 90% in some cases (81.5-90.1% for sheep and 84.7-92.6% for goats). However, the periodical use of screening tests able to detect quinolones, macrolides or aminoglycosides would be recommended to carry out more efficient screening and ensure the safety of milk and dairy products from sheep and goats.

Ewe milk ,Aflatoxin M1 ,ELISA ,PRODUCCION ANIMAL ,Curd - Abstract
The importance of ewe milk lies in the production of high quality cheeses, such as Manchego cheese with a Protected Designation of Origin, whose safety must be guaranteed. In a 2-yr study, 407 bulk tank milk samples from farms and 82 silo milk and curd samples from cheese factories were collected from southeast Spain and tested for aflatoxin M1 (AFM1) using 2 commercial ELISA tests. Of these, 99.3% of the bulk tank samples had AFM1 levels below the European Union (EU) legal limit for milk (50 ng/kg), and well below the limit adopted by the Codex Alimentarius (500 ng/kg). Moreover, 98.8% of the silo milk and curd samples from cheese factories had AFM1 levels below the EU limit for milk. When considering median AFM1 concentrations, an average 4-fold increase was found in the final curd in relation to the corresponding silo milk. Control of AFM1 in Manchega ewe milk would enhance dairy product safety by the possible detection of faults in the manufacture of Manchego cheese., This study was financed by the Research Project PAI06-0068-3875 from the Junta de Comunidades de Castilla-La Mancha awarded to R. Rubio as a predoctoral grant (Ref. 07/039). The authors thank the personnel from the Centro Regional de Seleccion y Reproduccion Animal (Valdepenas, Spain), Consejo Regulador de la Denominacion de Origen Queso Manchego (Valdepenas, Spain), Asociacion de Ganaderos de la Raza Manchega (Albacete, Spain) for their help with the milk composition and somatic cell analyses, and in collecting samples..

[EN] Aflatoxin M1 (AFM1 ) distribution in curd, whey, Manchego cheese, the traditional Spanish whey cheese Requesón and Requesón whey, and its stability during two different cold treatments, have been studied. Raw ewe¿s milk was artificially contaminated with AFM1 in a final concentration of 50 and 100 ng kg-1, and was used to produce Manchego cheese. AFM1 determinations were carried out by HPLC with fluorimetric detection after immunoaffinity clean-up. The mean AFM1 concentrations in the produced curd and Manchego cheese were approximately 2- and 3-fold higher than the initial milk they were made from, and the levels of this toxin remaining in whey were 42.3 % and 51.3 % of the initial concentrations. In the Requesón samples, the mean AFM1 values were 1.7 times higher than those in the corresponding whey, while 33.7 % and 44.4 % of the AFM1 concentration detected in milk also appeared in the Requesón whey. Short refrigeration and freezing periods did not affect the toxin levels in either curd or Requesón samples. When ewe¿s milk destined for Manchego cheese-making is AFM1 -contaminated at the EU limit level (50 ng kg-1) or double, a concentration of this toxin will appear in the manufactured products, but values will be considerably below the toxic doses (Tolerable Daily Intake = 2 ng kg-1 body weight per day), which poses a human health problem.
